Evaluation of the Wound Healing Potential of Aloe Vera Leaf Extract Containing Carbopol 934 as a Gelling Agent and Comparing with Sodium CMC and HPMC on Surgically Induced in Wound Wister Rats: A Preclinical Study

ABSTRACT Introduction: The restricted injury can occur in any tissue or organ and is caused by an external source. The toughness and adaptability of the delivery system are enhanced by the synthetic hydrophilic, biocompatible, and biodegradable stable polymer known as carbopol 934. Aloe vera is a plant belonging to the Liliaceae family that releases anthraquinones, a bitter liquid that has medicinal qualities. Aim: The current study is to determine if aloe vera gel containing Carbopol 934 can cure wounds in animal models used in experiments. Need of the Study: This review will offer a thorough examination of recent studies on the medicinal use of Aloe vera gel. Further study is required to establish the mechanism of action because certain areas, such as wound healing, have not received much attention in the scientific community. However, these biological materials must first be appropriately isolated and identified. Materials and Methods: Various centralizations of Carbopol 934, sodium CMC, and HPMC will be attempted, and lastly, gel that showed great spreadability and consistency will be chosen for wound mending properties of homegrown Aloe vera gel.

The Effect of Aloe vera on Skin and Its Commensals: Contribution of Acemannan in Curing Acne Caused by Propionibacterium acnes

Aloe vera is one of the most significant therapeutical plant species that belongs to the family Liliaceae. Aloe vera is composed of a high amount of water, with the remainder being dry matter. The dry matter contains a lot of bioactive compounds like carbohydrates, fats, and enzymes, with various therapeutic and antimicrobial properties. It can enhance the proliferation of cells and prevent cell damage by anti-oxidative properties (stimulating the secretion of superoxide dismutase and peroxidase). Human skin is colonized by microbes like fungi (Candida albicans), bacteria (Propionibacterium acnes, Staphylococcus aureus), and mites. These commensals are responsible for skin characteristics such as acidic pH, the pungent smell of sweat, etc. Human fetuses lack skin microbiota, and their skin is colonized after birth. Commensals present on the skin have a crucial role in training the human immune system against other pathogenic microbes. Propionibacterium acnes act as an opportunistic pathogen when the balance between the commensals is disturbed. We also emphasize the recent progress in identifying the aloe metabolite biosynthesis pathways and the associated enzyme machinery. The hyperproliferation of Propionibacterium acnes causes acne, and acemannan plays a significant role in its cure. Hence, we need to consider a new treatment approach based on the root cause of this dysbiosis.

Anti-inflammatory Capacity of a Medicinal herb extract, Anemarrhena asphodeloides, on In vivo and In vitro models-induced atopic dermatitis

Anemarrhena asphodeloides (AA) Bunge, a rhizomatous plant from the Liliaceae family, is traditionally utilized to manage inflammatory conditions. Nevertheless, its impact on atopic dermatitis (AD) and the associated molecular pathways have not yet been fully explored. This study explored the therapeutic effects of AA on AD both in vivo, using 2,4-dinitrofluorobenzene-induced NC/Nga mice, and in vitro, with tumor necrosis factor-α/interferon-γ-stimulated HaCaT keratinocytes. Topical application of AA ointment on the dorsal skin notably alleviated AD symptoms and skin lesions, enhanced the dermatitis score, and improved parameters such as the rate of trans-epidermal water loss, epidermal thickness, mast cell infiltration, systemic IgE levels, and cytokine expression. Furthermore, AA treatment significantly reduced serum levels of thymic stromal lymphopoietin (TSLP) and locally suppressed mRNA expression of thymus and activation-regulated chemokine (TARC) along with other relevant cytokines in affected skin. Both in vivo and in vitro applications of AA curtailed TSLP levels by inhibiting the expression of signal transducer and activator of transcription 6, a key regulator of pruritus and an initiator of mitogen-activated protein kinase signaling pathways. Additionally, AA affected the expression of tumor necrosis factor-like weak inducer of apoptosis/fibroblast growth factor-inducible 14, a pathway of interest in the study of cutaneous inflammatory diseases. Collectively, these findings propose that AA holds potential as an effective therapeutic agent for treating AD-induced skin inflammation.

Fusarium oxysporum causes the root rot disease of Polygonatum cyrtonema in China

Polygonatum cyrtonema, also known as Huangjing, belongs to the Liliaceae family and is a commonly used medicinal and edible plant in Asia. In recent years, P. cyrtonema root rot disease has frequently occurred in China, significantly impacting its yield and medicinal value. However, the pathogen of the disease has not yet been identified. In this study, we aimed to identify the pathogen causing the root rot disease of P. cyrtonema by applying morphological and molecular methods following Koch's postulates. Twelve fungal strains were isolated from nine diseased rhizomes of P. cyrtonema. Morphological analysis showed that the twelve isolates included eight colony types. Among that strain, HJ-5 has the typical characteristics of Fusarium oxysporum, including single-cell microconidia, chlamydospores, and sickle macroconidia. BLAST alignment and phylogenic tree based on the tef1, rpb2, β-tubulin, and ITS genes demonstrated that strain HJ-5 exhibits the highest similarity with Fusarium oxysporum. The strain HJ-5 is identified as F. oxysporum based on morphological and molecular characteristics. In addition, the pathogenicity test showed that among twelve isolates, only strain HJ-5 led to the rhizome softening and rotting on detached rhizomes and living plants of P. cyrtonema, consistent with symptoms observed in the field. To our knowledge, this is the first report on root rot disease in P. cyrtonema caused by F. oxysporum in China, which will provide a clear prevention and management target for the root rot disease of P. cyrtonema.

Peering through the hedge: Multiple datasets yield insights into the phylogenetic relationships and incongruences in the tribe Lilieae (Liliaceae)

The increasing use of genome-scale data has significantly facilitated phylogenetic analyses, contributing to the dissection of the underlying evolutionary mechanisms that shape phylogenetic incongruences, such as incomplete lineage sorting (ILS) and hybridization. Lilieae, a prominent member of the Liliaceae family, comprises four genera and approximately 260 species, representing 43% of all species within Liliaceae. They possess high ornamental, medicinal and edible values. Yet, no study has explored the validity of various genome-scale data in phylogenetic analyses within this tribe, nor have potential evolutionary mechanisms underlying its phylogenetic incongruences been investigated. Here, transcriptome, Angiosperms353, plastid and mitochondrial data, were collected from 50 to 93 samples of Lilieae, covering all four recognized genera. Multiple datasets were created and used for phylogenetic analyses based on concatenated and coalescent-based methods. Evolutionary rates of different datasets were calculated, and divergence times were estimated. Various approaches, including coalescence simulation, Quartet Sampling (QS), calculation of concordance factors (gCF and sCF), as well as MSCquartets and reticulate network inference, were carried out to infer the phylogenetic discordances and analyze their underlying mechanisms using a reduced 33-taxon dataset. Despite extensive phylogenetic discordances among gene trees, robust phylogenies were inferred from nuclear and plastid data compared to mitochondrial data, with lower synonymous substitution detected in mitochondrial genes than in nuclear and plastid genes. Significant ILS was detected across the phylogeny of Lilieae, with clear evidence of reticulate evolution identified. Divergence time estimation indicated that most of lineages in Lilieae diverged during a narrow time frame (ranging from 5.0 Ma to 10.0 Ma), consistent with the notion of rapid radiation evolution. Our results suggest that integrating transcriptomic and plastid data can serve as cost-effective and efficient tools for phylogenetic inference and evolutionary analysis within Lilieae, and Angiosperms353 data is also a favorable choice. Mitochondrial data are more suitable for phylogenetic analyses at higher taxonomic levels due to their stronger conservation and lower synonymous substitution rates. Significant phylogenetic incongruences detected in Lilieae were caused by both incomplete lineage sorting (ILS) and reticulate evolution, with hybridization and “ghost introgression” likely prevalent in the evolution of Lilieae species. Our findings provide new insights into the phylogeny of Lilieae, enhancing our understanding of the evolution of species in this tribe.

Effects of soil and phylogeny on sulfur and phosphorus concentrations in wild plants on volcanic and non-volcanic soils in Japan

ABSTRACT Andosols are soils characterized by relatively high sulfur concentrations, but also by their low phosphorus availability for crops and vegetables. We assessed the effect of soil type on the concentrations of sulfur and phosphorus in plants using handheld X-ray fluorescence (XRF) analysis on herbarium specimens collected from Andosols and non-volcanic soils in Japan. The sulfur concentrations in plants from Andosols were higher than plants from non-volcanic soils, but there was no significant difference between their foliar phosphorus concentrations. Only three specimens out of 1203 herbarium specimens were below the sulfur concentration (1000 mg kg−1) needed for adequate growth of crops, but about half of specimens were below that for phosphorus (2000 mg kg−1). The sulfur concentrations were high in herbaceous plants, especially in plants from the Brassicaceae and Liliaceae families. Overall, the results show that the sulfur concentrations in wild plants from Japan were higher in Andosols, with a low risk for sulfur deficiency. In contrast, the effect of soil type on the phosphorus concentrations in plants was small, and this may be explained because most wild plants grow under phosphorus-limiting conditions. Finally, the analysis reveals a strong correlation between sulfur and phosphorus concentrations in plants, suggesting the existence of a mechanism that controls the sulfur and phosphorus concentration ratios.

MELIORATION OF ALUMINIUM FLUORIDE TOXICITY BY ALOE VERA ON BLOOD PARAMETERS IN MALE ALBINO RATS

It is suspected that drinking water containing fluoride (F) and aluminum (Al) results in negative health effects in the human and animals. Its toxic effect in the especially on blood, brain, liver, and kidney. In this investigation, the effect of AlF3 blood disease was noted. Albino rats were treated either with WHO recommended or slightly higher F and Al levels in drinking water. Treatment solutions contained 0.05–10.0 mg/L of F, and 0.08–10.0 mg/L of Al, and the treatment period was 45 days. Aloe vera gel (Aloes) is a member of the family Liliaceae that is used as herbal or medicine in many cultures for different purposes. The present study was designed to observe the role of Aloe vera gel on blood parameters in rats. The present study was designed to assess the ameliorative effect of Aloe vera gel on aluminium fluoride induced toxic changes in blood parameters of albino rats. The present study was carried out 60 male albino rats that were randomly divided into three groups consisting of 20 rats in each group. Aluminium fluoride was gavages per orally using distill water as vehicle 200mg/kg b. w. to group II and Aloe vera 300mg/kg b. w. in distilled water was given along with AlF3 to group III for 45 days to study of ameliorative effects group I is a control group. Ten rats from each group were sacrificed at sixteenth and forty sixth day night interval. Entire changes were observed in blood cells. The haematological parameters TEC, Hb. Conc., MCV significant decrease treated with AlF3, and TLC, PVC, MCH, MCHC and ESR significant increase after 45 days treated with AlF3 compared with the control group. Treated with AlF3 along with Aloe vera gel all parameters significant increased compared with the control group. These results showed that Aloe vera gel have haematoprotective effects in experimently induced AlF3 rats. This study concluded that Aloe vera gel has haematoprotective effect against aluminium fluoride induced haematotoxicity.

Comparative Analysis of Phytochemical Composition and Antioxidant Properties of Smilax china Rhizome from Different Regions

This study aimed to investigate variations in the phytochemical compound contents and antioxidant potential of the ethanol rhizome extracts of Smilax china L., belonging to the Liliaceae family, from different parts of Korea, namely Uiwang (Mt. Gamnamugol), Gyeonggi Province (SC1); Geochang, Gyeongnam Province (SC2); Yeongwol, Gangwon Province (SC3); and Chungju, Chungbuk Province (SC4). The phenolic and flavonoid contents, radical scavenging activity, and proximate composition of the ethanol extracts from the rhizome samples were determined. The total polyphenol content (TPC) of the extracts ranged between 13.6 and 67.5 mg tannic acid equivalent/g. TPC analysis showed that TPC was higher in SC2 than in SC3, SC4, or SC1. Among the rhizome samples, the SC3 rhizomes had the highest total flavonoid content (TFC) (5.2 mg quercetin equivalents/g). Additionally, SC2 showed the highest radical scavenging activity against DPPH and ABTS+ radicals. Chemical characterization using UPLC/UV revealed that the extracts contained compounds such as apiin, kaempferol-3-rutinoside, and chlorogenic acid. Specifically, in SC2, chlorogenic acid was the dominant compound, which supported the levels observed in the UPLC/UV and HPLC/ELSD investigations. Dioscin, another phytochemical, was detected in SC2, SC3, and SC4, indicating the diversity of compounds among the rhizome extracts. Variations in the phytochemical content and antioxidant activity were observed in the extracts from the different regions, underlining the role of geographical variation in the functional characteristics of S. china. The observed differences could have important implications for the medicinal use of S. china extracts in applications such as anti-inflammatory treatments, diabetes management, and potential anticancer therapies. This study underscores the critical need to consider geographical origin when sourcing and utilizing S. china for therapeutic purposes, as it may significantly impact its bioactive profile and efficacy.

Study on Synthesis and Regulation of PPVI and PPVII in Paris polyphylla with UV.

Paris polyphylla Smith var. Chinensis (Franch.) Hara is a medicinal plant that belongs to the Liliaceae family. Its main components are parissaponins, which have excellent medicinal effects such as anti-inflammatory, anti-tumor, etc. Improving the quality of parissaponins through artificial directional regulation has emerged as a practice to meet medical demand and is a new research hotspot. In this paper, P. polyphylla plants were treated with UVA, UVB, and UVC, and the contents of PolyPhyllin VI (PPVI) and PolyPhyllin VII (PPVII), saponin synthase (squalene synthase, SS; cycloartenol synthase, CAS; cytochrome P450, CYP450; and glycosyl transferases, GT) activity, MDA, and the photosynthetic pigment indexes were measured and analyzed. The results showed that PPVII content increased by 32.43% with UVC treatment after 4 h (3.43 mg/g), but the PPVI and PPVII contents in the other groups decreased compared with CK (control group) and they did not return to the original level after 4 h. SS, CAS, CYP450, and GT synthases were activated in varying degrees via UV treatment and increased, respectively, by 22.93%, 10.83%, 20.15%, and 25.98%. Among them, GT, as the last of the synthetases, had a shorter response time to UVB (30 min) and UVC (15 min); the difference was sensible compared with CK. Moreover, UV had a stressing effect and promoted the rapid accumulation of MDA content (increased 17.66%, 34.53%, and 9.65%) and carotenoid (increased 7.58, 5.60, and 7.76 times) within 4 h compared to CK. UVB and UVC radiation visibly improved chlorophyll a content (42.56% and 35.45%), but UVA did not, and the change in chlorophyll b content showed no overt statistical difference. In addition, PPVI and PPVII were negatively correlated with SS, CAS, carotenoids, and MDA (p < 0.05) and positively correlated with CYP450, GT, and chlorophyll a (p < 0.05). This study provides a theoretical basis for using UV light to regulate secondary metabolism in P. polyphylla, which is of great value for production management.

Investigating Changes in Pharmacokinetics of Steroidal Alkaloids from a Hydroethanolic Fritillariae thunbergii Bulbus Extract in 2,4-Dinitrobenzene Sulfonic Acid-Induced Colitis Rats.

Fritillariae thunbergii Bulbus (FTB), a member of the Liliaceae family, has a long history of use in many herbal formulations for traditional and modern clinical applications to treat various infections and inflammation. To understand FTB's diverse physiochemical properties, it is important to determine the pharmacokinetic properties of its active constituents, the steroidal alkaloids. The aim of the present study was to investigate the pharmacokinetic alterations of the alkaloids, the active components of FTB, in the presence of colitis. A single oral dose of FTB (1 g/kg) was treated to a 2,4-dinitrobenzene sulfonic acid (DNBS)-induced colitis rat model to assess whether the colitis condition could influence the pharmacokinetics of the major alkaloids present in FTB. Among the four major alkaloids, peimisine exhibited a significantly increased systemic exposure, approximately five times higher, under the colitis condition compared with the normal state. Meanwhile, peimine, peiminine, and sipeimine exhibited shorter half-lives in the DNBS group without significant changes in systemic absorption. As herbal medicine may contain active substances with different or opposing efficacies, careful consideration of pharmacokinetic changes in individual components due to diseases is necessary. Further experiments on peimisine are required to ensure the effectiveness and safety of FTB's clinical application in the presence of colitis.

First report of Alternaria alternata causing leaf spot on Polygonatum kingianum in China.

Polygonatum kingianum is a Chinese herbal medicine that belongs to the genus Polygonatum of the family Liliaceae. In June 2023, Polygonatum kingianum Coll. et Hemsl. in nurseries in Qujing, Yunnan Province, China, showed irregular brown spots on the leaves, whole leaf necrosis, and plant death in serious cases, with an incidence of 10-20% (Fig. S1). To identify the pathogens of P. kingianum, six diseased samples were collected from nurseries with 0.6 acre. These diseased sample leaves were soaked in 0.1% HgCl2 for 1 min and 75% ethanol for 2 min and then rinsed thrice with sterile water. Treated leaves were cut into small pieces (5×5 mm) and cultured on potato dextrose agar (PDA) for five days at 28°C. Total thirteen fungal strains were isolated from PDA medium. The nuclear ribosomal internal transcribed spacer of ribosomal DNA (ITS rDNA) region of these 13 strains was amplified by polymerase chain reaction (PCR) using universal primers ITSI/ITS4 (White et al. 1990). Sequencing and BLAST of the ITS region on NCBI showed that 11 out of 13 fungal strains belonged to the genus Alternaria, with an identity ≥99%. We selected one of the Alternaria strains, HJ-A1, for further study. The HJ-A1 colony appeared grayish brown white-to-gray with a flocculent texture on the front side and a dark gray underside on the PDA medium (Fig. S1). The conidiophores appeared brown, either single or branched, and produced numerous short conidial chains. The conidia were obclavate to obpyriform or ellipsoid in shape and contained 1-4 transverse septa and 0-2 oblique septa. The conidial diameter was 27.30µm in length and 12.27µm in width. (Fig. S1). To further determine the species of HJA1, the genomic DNA of HJ-A1 was extracted using the Lysis Buffer for PCR (AG, Hunan, China). Four Alternaria genomic DNA regions including the ITS, translation elongation factor 1-α gene (TEF1-α), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), and Alternaria major allergen gene (Alt a1) were amplified by PCR using the primers as previously reported (Woudenberg et al. 2013, Hong et al. 2005). Sequence analysis revealed that the ITS (484bp) of HJ-A1 (NCBI No. PP082633), TEF1-α (267bp) of HJ-A1 (NCBI No. PP419893), GAPDH (582bp) of HJ-A1 (NCBI No. PP419892), and Alt a1 (522bp) of HJ-A1 (NCBI No. PP228046) shared the highest identity with A. alternata respectively (99≥%). A maximum likelihood phylogenetic tree was constructed with the combined sequence data sets of ITS, GAPDH, TEF, and Alt a1 using MEGA 7. The results showed that HJ-A1 strain clustered with A. alternate (Fig. S2). The pathogenicity of HJ-A1 was tested according to Koch's postulates by inoculating HJ-A1 conidia suspension (2×105 conidia/mL) into leaves of 1-year-old P. kingianum, with sterile water as a control. Each treatment group included 3 plants with 3 replicates. The tested plants were planted in a phytotron at 28℃ and 90% humidity. Three days after inoculation, symptoms similar to those under natural conditions were observed in the HJ-A1-inoculated plants, whereas no symptoms were observed in the control plants (Fig. S1). The same fungal strains were re-isolated from inoculated leaves and identified by morphologically and sequence of ITS. Previous studies showed that Alternaria alternata funji cause many plant diseases, such as fig fruit rot (Latinović N et al. 2014)，daylily leaf spot (Huang D et al. 2022), fruit blight on sesame (Cheng H et al. 2021)，leaf spot of Cynanchum atratum Bunge (Sun H et al. 2021) and so on. To our knowledge, this is the first report of A. alternata causing P. kingianum leaf spot in China. The discovery of this pathogen will help to guide the protection and control of P. kingianum disease.

Botanical characterization, phytochemistry, biosynthesis, pharmacology clinical application, and breeding techniques of the Chinese herbal medicine Fritillaria unibracteata.

Fritillaria unibracteata (FRU) belongs to the genus Fritillaria of the Liliaceae family. It is one of the original plants of the Chinese medicinal material "Chuanbeimu" and also a biological resource featured in the Tibetan Plateau of China. The dried bulbs of FRU are used in traditional Chinese medicine. The chemical constituents of FRU that have been isolated and identified include alkaloids, sterols, organic acids and their esters, nucleosides and volatile oils. FRU has antitussive, expectorant, anti-asthmatic, anti-inflammatory, antibacterial, acute lung injury-reducing, antifibrosis, antitumor, and other pharmacological effects. This valuable plant has an extremely high market demand, and over the years, due to over-exploitation, FRU has now been listed as a key species that is endangered and scarcely cultivated in China as a traditional Chinese medicinal herb. However, research on FRU is rare, and its effective components, resource control, and mechanisms of action need further study. This review systematically discusses the herbal characteristics, resource distribution, chemical composition, biosynthesis, pharmacological effects, clinical application, and breeding techniques of FRU, hoping to provide a reference for further research and the use of FRU.

DISPERAL OF THE LILIACEAE REPRESENTATIVES IN RELATION TO THE STRUCTURE OF THEIR REPRODUCTIVE ORGANS

The Liliaceae family is a terminal one in the order Liliales sensu APG IV (2016) and consists of 15 genera with more than 700 species. The family’s geographical range covers most of the Northern hemisphere and extends through several natural zones, from forest tundra (Gagea species) to tropical forests (Tricyrtis imeldae Guthnick), within three continents, i. e. Eurasia, North America and Africa. Most Liliaceous genera occur both in Eurasia and North America. Representatives of Liliaceae develop coenocarpous fleshly indehiscent berries or dry dehiscent capsules. In most cases, multi-seeded berries themselves are a diaspore, whereas in the case of capsules, the seeds are normally a diaspora. The capsules play a vital role in seed dispersal. Structural adaptations of fruits allowed representatives of Liliaceae to spread into the territories that make up the modern range of the family.The aim of the study is to determine the principal patterns of fruit development for the representatives of Liliaceae with different types of dissemination. The study is based on the investigation of morphological and anatomical structure of fruits which is related to geography, ecology and biology of the Liliaceae taxa dissemination.The study has revealed that the wind is the most typical and widespread agent of dissemination for the investigated representatives of Liliaceae. The specialized capsules responsible for anemochory, i.e. auto-anemochory and anemochionochory (mainly in representatives of the ground cover of deciduous forests in temperate and subtropical climatic zones of the Holarctic Kingdom), are characteristic of representatives of the Lilioideae subfamily. Unlike the capsules supporting the anemochory, which actively participate in dissemination, the primary function of capsules of baromyrmecochorous representatives of Liliaceae is seed production rather than their dispersal, which is reflected in the anatomical structure of the capsules, with numerous intercellular spaces in the pericarp and almost complete lack of its lignification. The endozoochory of fleshly berries of Liliaceae is effective for dispersal by long-distance transport, primarily by birds. Supposedly, the ornitochory prevents dispersal among a large number of ecosystems, which is echoed in the ranges of Clintonia, Prosartes and Streptopus genera, representatives of the ground cover of coniferous and broadleaf forests of the Holarctic Kingdom.

An anti-mitotic compound, (+)-6-tuliposide A, isolated from the Canadian glacier lily, Erythronium grandiflorum

The Canadian prairie ecosystem is subjected to abiotic and biotic conditions that induce plants to produce secondary metabolites that affect mammalian physiology. Extracts prepared from certain plant species native to Canadian prairie and montane cordillera ecosystems have previously been shown to have anti-mitotic activity on human cancer cell lines. In this study, we investigated the glacier lily, Erythronium grandiflorum (Liliaceae), in which the species was the most phylogenetically distant from Asteraceae and had anti-mitotic activity. When added to cell lines, E. grandiflorum extracts induced rounded cell morphology and arrested cells in the G2/M phase of the cell cycle. Of the cells that displayed a rounded phenotype, all were positive for phospho-histone H3 and contained a distorted mitotic spindle. This anti-mitotic activity was distinct from that of the compound colchicine, which has been previously isolated from the Liliaceae family. By biology-guided fractionation, we isolated the natural product (+)-6-tuliposide A and are the first to report its anti-mitotic activity. These results reveal a chemical motif in secondary metabolites and expand the range of Canadian prairie plants with anti-mitotic activity that can become new scientific tools or used in the development of anti-proliferative medicines.

Effects of Biofertilizers in Improving the Growth and Development of the Traditional Medicinal Plant Aloe vera L. (Aloe barbadensis Miller)

Abstract: Aloe vera L. (Aloe barbadensis Miller) is a very common water deficit-resistant plant which has immense medicinal properties. It is a fleshy plant belonging to the Liliaceae family. Aloe barbadensis has enormous medicinal value. According to historical records, it has been used in folk and traditional medicine in different parts and regions of the world for ages. Aloe vera is widely used in Ayurvedacharya and Unani medicine. The plant is a rich source of potent medicinal phytocomponents, each with pronounced medicinal properties. Primarily, Aloe gel is considered one of Mother Nature’s magical formulations for treating and curing various health ailments, including skin diseases, hair fall, indigestion, inflammation, and many others. Studies revealed that the use of biofertilizers significantly improves the growth and development of the Aloe plant. The quality and quantity of the constituents of Aloe vera gel are also reported to improve significantly with the use of biofertilizers. Biofertilizers, when used alone or in combination, are reported to influence the length, width, biomass, and phytoconstituents of the leaves of the plant. Biofertilizers, which are environment friendly and more effective on Aloe, can thus be considered a better substitute for other fertilizers for boosting the qualitative and quantitative yield of the magical medicinal plant, Aloe barbadensis.

Anti-Aging in Caenorhabditis elegans of Polysaccharides from Polygonatum cyrtonema Hua.

Polygonatum cyrtonema Hua, the dried rhizome of Polygonum multiflorum from the Liliaceae family, is a widely used medicinal herb with a long history of application. Its main active ingredients are polysaccharides, which have been demonstrated in contemporary studies to effectively delay the aging process. In the present study, homogeneous polysaccharide (PCP-1) was obtained after the purification and isolation of polysaccharides from Polygonatum cyrtonema Hua (PCP). The anti-aging activities of both were compared, and the possible mechanism of action for exerting anti-aging activity was explored using Caenorhabditis elegans (C. elegans). Research has indicated that PCP and PCP-1 exhibit potent anti-oxidant and anti-aging properties. Of particular note is that PCP-1 acts better than PCP. The two were able to prolong the lifespan of nematodes, improve the stress resistance of nematodes, reduce the accumulation of lipofuscin in the intestine, decrease the content of ROS and MDA in the body, increase the activity of the antioxidant enzymes SOD and CAT, promote the nuclear translocation of DAF-16, down-regulate the mRNA levels of the age-1 and daf-2 genes of the IIS pathway in nematodes, and up-regulate the expression of the daf-16, skn-1, sod-3, and hsp-16.2 genes. Based on the aforementioned findings, it is possible that the mechanism by which PCP and PCP-1 exert anti-aging effects may be through negative regulation of the IIS pathway, activation of the transcription factor DAF-16/FOXO, and enhancement of oxidative defenses and stress resistance in nematodes. Overall, the present study illustrated the great potential of polysaccharides from Polygonatum cyrtonema Hua in anti-aging and antioxidant activities. Specifically, PCP-1 demonstrated superior characteristics, which provides a reference for the future development of Polygonatum cyrtonema Hua polysaccharides.

Phytochemicals demonstrate potential fungicidal activity against Fusarium commune, a newly identified pathogenic fungus causing rhizome rot in Polygonatum cyrtonema (giant Chinese Solomon's seal)

AbstractPolygonatum cyrtonema (giant Chinese Solomon's seal) is a perennial herb belonging to the family Liliaceae, with significant medicinal and dietary value. However, a severe rhizome rot has led to a decline in the yield and quality of this species. In this study, a fungus was isolated from symptomatic rhizome samples and identified as Fusarium commune through molecular and morphological analyses. In pathogenicity tests, the identification of F. commune as the causative agent of rhizome rot was confirmed by fulfilling Koch's postulates. Biological characteristics indicated that the optimal growth conditions for F. commune were a temperature of 25°C, pH of 8, carbon source of soluble starch, nitrogen source of peptone and a photoperiod of 24 h light. In order to reduce the use of chemical fungicides and explore natural substances to control the disease, the sensitivity of F. commune to seven phytochemicals was studied. Four phytochemicals (honokiol, 2‐allylphenol, magnolol and carvacrol) showed inhibitory activity, with honokiol having a 50% of the maximal effect concentration (EC50) of 9.99 ± 0.14 mg/L. The results of pot experiment showed that the four phytochemicals had significant control efficacy on the rhizome rot of P. cyrtonema, and the highest control efficacy was observed with honokiol. These findings provide a scientific basis for the control of rhizome rot in P. cyrtonema.

Sensitive and accurate determination of oil-soluble and water-soluble organosulfur compounds in garlic matrix using reversed phase-high performance liquid chromatography.

Garlic is in the family Liliaceae and has many different constituents such as organic sulfur compounds, amino acids, carbohydrates, minerals, and vitamins. In this work, a simple, sensitive, and accurate analytical method was developed for the determination of selected organosulfur compounds (OSCs) in garlic bulbs using reversed phase-high performance liquid chromatography (RP-HPLC). Oil-soluble and water-soluble OSCs were extracted from the garlic samples via acetonitrile and deionized water, respectively. The OSCs were separated on a Phenomenex C18 (250 mm, 4 mm, 5mm) column and the monitoring was performed with a UV detector at 220 nm. An isocratic mobile phase comprising of 0.10 M trifluoroacetic acid (TFA) in 85% acetonitrile (ACN) and 0.10 M TFA in distilled water (DW) (90: 10% v/v) was used to elute the analytes. Under optimum experimental conditions, the limits of detection (LOD) for the analytes were calculated in the range of 0.09 to 0.17 mg/kg. For the garlic sample extracts analyzed under optimal instrumental conditions, DAS (diallyl sulfide), DADS (diallyl disulfide), and DATS (diallyl trisulfide) were detected in the ranges of 8.0 to 32.5 mg/kg, 20.4 to 67.3 mg/kg, and 60.7 to 356.6 mg/kg, respectively. Spiked recovery experiments were conducted on the garlic samples to confirm the method's applicability and accuracy. The recovery results ranged between 39.0% and 90.9% for the garlic samples extracted with deionized water. The developed method is simple, precise, accurate, reliable, and time-effective for the determination of OSCs. Additionally, the green profile of the developed method was investigated by using AGREEprep software and the greenness score was recorded as 0.65, indicating that the method developed is environmentally friendly.
