A Comparative Study on the in vitro Cytotoxicity and Anti-Cancer Properties of Gold Nanoparticles Derived from Elettaria cardamomum

Comprehensive Evaluation and Selection of Cardamom (Elettaria cardamomum (L.) Maton) Germplasm Using Morphological Traits.

Cardamom (Elettaria cardamomum (L.) Maton) plays a crucial role in Guatemala's agriculture, supporting local families and covering 169,429.29 ha (making it the world's leading producer). Since its introduction to Guatemala in 1910, limited research has focused on unraveling the diversity and defining morphological traits critical for selecting excellent accessions. In this study, we examined 17 morphological traits across 288 accessions to identify key features associated with the germplasm. The comprehensive analysis employed principal component analysis, a morphological composite value (F-value), linear regression, and hierarchical clustering. The Shannon-Wiener diversity index ranged from 0.10 to 2.02, indicating the variation in diversity among traits. Principal component analysis and hierarchical clustering revealed six distinct germplasm groups. The comprehensive analysis facilitated the selection of 14 excellent accessions, and the regression equation incorporating criteria such as plant height, capsule color, panicle number per plant, panicle length, rhizome color, cluster number per panicle, cluster node length, and capsule number per cluster to identify cardamom germplasm. To develop a conservation strategy for the two putative foreign varieties ('Malabar' and 'Mysore'/'Vazhukka') introduced in Guatemala based on plant height, another 12 accessions were selected with a second comprehensive evaluation. This information offers insights into cardamom diversity for informed selection enhancing national utilization, productivity, and conservation.

Optimizing mycorrhizal fungi application for improved nutrient uptake, growth, and disease resistance in cardamom seedlings (Elettaria cardamomum (L.) Maton)

This study evaluated the impact of various doses (5, 10, 15 g) and application sequences (1, 2, or 3 times at monthly intervals) of arbuscular mycorrhizal (AM) fungal inoculum on cardamom seedlings over two years (2020–2021 and 2021–2022). The results indicated that the dosage of AM inoculum had a more substantial effect on the seedlings than the application sequence. A 10 g dose significantly increased shoot length and dry weight, while three applications of 5 g each improved the number of fibrous roots. Although potassium uptake was not affected, phosphorus and calcium uptake were highest with the 10 g dose. Arbuscular mycorrhizal inoculation also enhanced phosphatase activity in the rhizosphere, with 5 g improving acid phosphatase and 10 g improving alkaline phosphatase activity. Disease incidence, including seedling rot was lower with the 10 g dose, and additional sequential applications did not further reduce disease. Structural equation modeling (SEM) revealed that AM colonization positively influenced dry weight through the number of fibrous roots, showing a strong relationship between AM dose, colonization, spore count, and mycorrhizal dependency. This study indicates that applying a 10 g dose of AM fungal inoculum can be particularly beneficial in agroecosystems for improving cardamom seedling growth, nutrient uptake, and disease resistance.

Bioactive Compounds from Natural Products as RHOA/ROCK and VEGFR1 Inhibitors: An In-silico Approach for Developing Therapeutics for ALI/ARDS

Acute Respiratory Distress Syndrome (ARDS) is a dangerous lung condition characterised by non-cardiogenic pulmonary edoema caused by various factors, including inflammation and hypoxia. It is a more severe and evolved form of Acute Lung Injury (ALI) and requires the patient to be on mechanical ventilation for survival. Several medicinal plants, herbs, oils, and natural extracts have been studied for their anti-inflammatory properties and their targeted action on respiratory disorders. The target of the current study is to elaborate on the target-specific action of bioactive compounds from natural products by Molecular Docking and study their drug-likeness along with their other important pharmacokinetic properties. Bioactive compounds (total 71) from Zingiber officinale (ginger), Trifolium pratense (red clover), Curcuma longa (turmeric), Melaleuca alternifolia (tea tree), Ocimum tenuiflorum (Tulsi), Chlorophytum borivilianum (Safed Musli), Cinnamomum cassia (cinnamon), Elettaria cardamomum (cardamom), and Glycine max (soybean) were selected to be investigated and were screened against RhoA and VEGFR1. The ADMET properties and drug-likeness of the bioactive compounds were studied using Molinspiration and ADMETlab 2.0. Docking studies revealed that Hecogenin (-8.4 and -10.3 kcal/mol), Neotigogenin (-7.7 and -9.8 kcal/mol), and Neohecogenin (-7.6 and -9.7 kcal/mol) produced the best docking results, showing the lowest binding energies for RhoA and VEGFR1, respectively. These energies were found to be comparable to the standard ligands Fasudil (-7.3 kcal/mol for RhoA) and Pazopanib (-8.0 kcal/mol for VEGFR1) for the selected targets. Moreover, Stigmasterol (-7.6 kcal/mol) and Genistein (-8.4 kcal/mol) showed a good binding affinity with RhoA and VEGFR1, respectively. The ADME properties of these molecules were also studied. Thus, the best-docked ligands mentioned above can be used as potential novel compounds against these two targets to develop therapeutics against ARDS. Further in-vitro and in-vivo experiments are required to cement these claims and prepare next-generation natural therapeutics for ARDS.

Nutritional profiling and antioxidant potential of corn silk (Maydis stigma) powder for the development of corn silk tea

AbstractThe study aimed to analyse the nutritional and antioxidant potential of corn silk based formulated tea. Four corn silk tea formulations were developed, one with corn silk only and three using different flavouring herbal/spicing agents, namely lemongrass, green cardamom, and cinnamon. Microwave dried corn silk powder and corn silk tea infusions were analysed for chemical composition. Organoleptic evaluation was also done for tea infusions. The results of chemical evaluation showed that corn silk powder is rich in protein (20.78%), dietary fibre (48.93%), calcium (139.5 mg/100 g), magnesium (163.9 mg/100 g), potassium (1,406 mg/100 g), total phenols (1,365 mg GAE/100 g), and flavonoids (370.8 mg QE/100 g). The antioxidant activity of corn silk powder was observed as 84.95% DPPH inhibition. Maysin content of corn silk powder was 3.65 mg/100 g. Chemical analysis of corn silk tea infusions showed that the addition of flavours significantly enhanced the minerals, total phenols, and flavonoids contents and the antioxidant activity as compared to the tea formulated with only corn silk powder. Results of organoleptic evaluation showed that all four corn silk tea formulations were highly acceptable. Overall improvement in nutritional and antioxidant contents was found in corn silk tea with added flavours.

Green synthesis of NiO and NiO@graphene oxide nanomaterials using Elettaria cardamomum leaves: Structural and electrochemical studies

An eco-friendly synthetic route was developed for the formation of nickel oxide (NiOaq and NiOet) nanoparticles (NPs) by treating Ni(NO3)2.6H2O with aqueous/ethanolic extracts of Elettaria cardamomum leaves; the same reaction was performed in the presence of graphene oxide (GO) to produce NiOaq@GO and NiOet@GO nanocomposites (NCs), respectively. The NMs were characterized by XRD, FT-IR, SEM, EDX, UV–visible spectroscopy, and TGA-DSC analysis. They were also subjected to electrochemical investigations and photocatalytic degradation of crystal violet (CV) dye. XRD analysis revealed the average crystallite sizes of 8.84–14.07 nm with a face-centered cubic form of NiO NPs and a hexagonal structure of their nanocomposites with GO. FT-IR spectroscopy confirmed the presence of Ni-O vibrations at 443-436 cm−1. SEM images confirmed the spherical morphology of NiO NPs while NiOaq@GO NCs contained randomly aggregated, thin, and wrinkled graphene sheets. NiOaq and NiOet have shown particle sizes of 27.7–30.63 nm which were decreased to 19.33–26.39 nm in their respective NiOaq@GO and NiOet@GO NCs. EDX spectra verified the homogeneous distribution of elements (Ni, O, C) on the surface of the particles. The synthesized NCs have shown smaller band gaps (NiOaq@GO = 3.74 eV; NiOet@GO = 3.34 eV) as compared to their respective NPs (NiOaq = 5.0 eV; NiOet = 3.89 eV). TGA/DSC data was used to find the thermal stabilities, glass transition temperatures, and enthalpies. Cyclic voltammetry measurements exhibited distinct oxidation and reduction peaks. NCs exhibited better potential as electrode materials for supercapacitor applications as compared to their respective NPs. NiOet@GO exhibited the best electrochemical performance and photocatalytic degradation efficiency of CV dye. After 120 min exposure to sunlight, the degradation coefficient of CV was observed to be 82.93, 86.34, 89.99, 90.27 and 81.65 % in the presence of NiOaq, NiOet, NiOaq@GO, NiOet@GO and GO, respectively.

Attenuation of L-NAME-induced Hypertension in Rats with Elettaria cardamomum–Low-dose Amlodipine Combination: A Possible Synergism of Covasodilatory Effect

Background Hypertension is a prevalent chronic disorder that affects approximately 1.28 billion adults worldwide. In the use of amlodipine, though it is a cost-effective antihypertensive agent, it causes side effect that may lead to discontinuation of the medication. Purpose To examine the effect of the combination of Elettaria cardamomum plus a low dose of amlodipine on Nω-nitro-l-arginine methyl ester (L-NAME)-induced hypertensive rat model. Materials and Methods Thirty adult male Wistar rats were randomized into five groups of six rats, respectively. The standard control group received only normal saline (first group). The other four groups received L-NAME (40 mg/kg/day, orally) for 21 days as follows: Group 2 served as L-NAME group only; Group 3 was given E. cardamomum (400 mg/kg/day, orally); Group 4 received amlodipine (5 mg/kg/day, orally); Group 5 received E. cardamomum (400 mg/kg/day, orally) + a low dose of amlodipine (2.5 mg/kg/day, orally) and served as the combination treatment group. Twenty-four hours after the last treatment, blood pressure was measured, then blood samples were collected, rats were sacrificed, and hearts and kidneys were harvested. Serum levels of lipids, liver enzymes, urea, and creatinine were determined. Results L-NAME administration induced a notable increase in systolic, diastolic, and mean arterial blood pressure, with significant changes in biochemical parameters. However, administration of E. cardamomum alone or in combination with a low dose of amlodipine showed a better reduction in systolic and diastolic blood pressure than amlodipine alone. Consequently, effects on liver enzymes, lipid profile, and cardiorenal pathology were significantly improved with combination treatment compared with amlodipine alone. Conclusion The present study has shown that the E. cardamomum–low-dose amlodipine combination could be beneficial in lowering blood pressure without the attendant adverse effects associated with the normal dose of amlodipine alone. This could be due to covasorelaxant effects.

Improving the Cardamom Marketing: Assessing the Marketing Efficiency of Cardamom in Theni District, Tamil Nadu

Introduction: The cardamom is the oldest spices and belongs to Zingiberaceae family. It is cultivated in the thick shady, rainy forests of the Western Ghats of the South India. The major growing states are Kerala, Karnataka and Tamil Nadu in reference to green cardamom (Small) and its botanical name Elettaria cardamomum. The part of Theni district is constituted by thick vegetations of hills of Western Ghats and Cumbum Valley at Bodi and Uthamapalayam taluk. In these areas, the farmers are cultivating the Cardamom. This study aims to find out the socio-economic characters, marketing behavior, assess the marketing efficiency of different supply channels and ranking the major problems faced by farmers to market their agricultural product. Methodology: The author used both primary and secondary data. The maximum area covered by cardamom was used as criteria for selecting the blocks. Purposive random sampling method was used to select the villages and the data was collected from the 60 farmers and other stakeholders using well-structured questionnaire. The descriptive statistics and percentage analysis were used for interpreting the results. For marketing analysis, marketing costs, marketing margin and price spread were estimated. For marketing efficiency, Acharya’s method (2003) was used. Results: The 34 respondents with 56.67 percent were found to be 21-35 years of age group. It was found that 7 respondents only with 11.67 percent and 26 respondents with 43.33 percent were found to be illiterate and the annual turnover of 1-5 lakh respectively. Using Acharya’s method (2003), the marketing efficiency of the channel I, II, III were 5.92, 9.97, 7.27 respectively. The price spread in the marketing channel I, II, and III are Rs. 295.94 per Kg, Rs. 163.54 per Kg and 229.48 per Kg respectively. It was shown that channel II is efficient due to high efficiency value and less price spread. Producer in the marketing channel II had highest share (90.88) in consumer rupee. The result showed that the Lack of timely adequate funds were major problem faced by the cardamom farmers with garret mean score of 65.23. The financial problems were common in the respondents. Conclusion: Marketing channel II was efficient because the spice auction center plays a vital role in protecting the farmer as well as consumer from the malpractices and exploitation of Intermediaries and to provide the transparency in trading operations of cardamom. The government may increase the financial assistance or technical support program to support the cardamom growers of the Tamil Nadu. The board should educate the farmers to grade or sort the cardamom before entering the e-Auction center to get better price for better quality of the commodity and to expand the pilot project of separate e-auctions for lab tested cardamom for artificial colours and pesticidal residues to potential markets of Tamil Nadu.

The cardamom conundrum resolved: Recircumscription and placement of Elettaria in the only pantropically distributed ginger lineage

AbstractThe overarching aim of the present study is to sort out the taxonomy of a group of gingers that include the useful and worldwide economically important green cardamom, Elettaria cardamomum, and its wild relatives, to highlight potentially overlooked genetic resources. These species occur naturally in India and Sri Lanka, and our study facilitates more appropriate management priorities for the remaining forest fragments in which they occur. We used NGS Hyb‐Seq methods and sampled four species of the Alpinia I (Fax) clade, six representatives of Aframomum and Renealmia as well as two other basally flowering Sri Lankan species. This is the only pantropically distributed lineage within the entire family, and our result shows that the Alpinia I clade in fact is simply the genus Elettaria (confined to India and Sri Lanka), which is sister to the genera Aframomum (Africa) and Renealmia (Africa and Neotropics). The taxonomic implications are: (1) a recircumscription of Elettaria comprising seven species (E. cardamomum, E. ensal, E. floribunda, E. involucrata, E. rufescens as well as two new species, E. facifera and E. tulipifera described here); (2) the Sri Lankan endemic genus Cyphostigma should be retained; (3) the new monotypic genus, Srilankanthus endemic in Sri Lanka, is described with S. nemoralis, formerly Amomum nemorale, as type. A key is provided to the seven species of Elettaria and lectotypifications are made for five species (Cyphostigma pulchellum, Elettaria floribunda, E. involucrata, E. nemoralis, E. rufescens).

In Vitro Anticancer Potential of Cardamom (Elettaria cardamomum) Essential Oil Against TNBC, Glioma and Kidney Cancer

Background: Green cardamom (Elettaria cardamomum (L.) Maton), a member of the Zingiberaceae family, is widely recognized for its use as a spice and traditional medicine. It is commonly used for treating gastric, cardiac, and kidney disorders, as well as infections and inflammatory conditions. Cardamom essential oil, known for its high content of bioactive compounds such as 1,8-cineole and α-terpinyl acetate, has been studied for its diverse biological activities, including antioxidant, antibacterial, anti-inflammatory, and anticancer effects. However, little is known about its anticancer potential against MDA-MB-231 (triple-negative breast cancer), U87 (glioblastoma), and HEK 293 (kidney) cell lines, especially in the context of cardamom oil sourced from Iraq. Methods: Cardamom essential oil was extracted via hydro-distillation from cardamom fruits collected in Erbil, Iraq, and its chemical composition was analyzed using gas chromatography-mass spectrometry (GC-MS). The oil’s anticancer activity was evaluated using the MTT assay against MDA-MB-231, U87, and HEK 293 cell lines. The cells were treated with various concentrations of cardamom essential oil, and cell viability was measured after 24 hours. The IC50 values were calculated to determine the oil’s efficacy. Results: GC-MS analysis revealed 33 compounds in the essential oil, with 1,8-cineole (42.37%) and α-terpinyl acetate (22.14%) being the predominant constituents. The MTT assay demonstrated that cardamom essential oil significantly reduced cell viability in MDA-MB-231 and HEK 293 cell lines in a dose-dependent manner, with IC50 values of 96.95 µl/ml and 157.44 µl/ml, respectively. However, the oil was less effective against U87 cells, showing only 40.67% inhibition at the highest concentration (500 µl/ml). Conclusion: Cardamom essential oil, rich in 1,8-cineole and α-terpinyl acetate, exhibited strong anticancer activity against MDA-MB-231 and HEK 293 cell lines, highlighting its potential as a therapeutic agent for triple-negative breast cancer. Further studies are needed to explore its full potential and mechanisms of action against different cancer types.

Enhanced healing of burn wounds by multifunctional alginate-chitosan hydrogel enclosing silymarin and zinc ‎oxide ‎nanoparticles

Multifunctional wound dressings have been applied for burn injuries to avoid complications and promote tissue regeneration. In the present study, we fabricated a natural alginate-chitosan hydrogel comprising silymarin and green-synthesized zinc ‎oxide ‎nanoparticles (ZnO NPs). Then, the physicochemical attributes of ZnO NPs and loaded hydrogels were analyzed. Afterward, wound healing efficacy was evaluated in a rat model of full-thickness dermal burn wounds. The findings indicated that ZnO NPs were synthesized via reduction with phytochemicals from Elettaria cardamomum seeds extract. The microscopic images exhibited fairly spherical ZnO NPs (35-45nm), and elemental analysis verified the relevant composition. The hydrogel, containing silymarin and biosynthesized ZnO NPs, displayed a uniform appearance, smooth surfaces, and a porous structure. Moreover, infrared spectroscopy ‎identified functional groups, confirming the successful loading without adverse interactions. The obtained hydrogel exhibited great water absorption, high porosity, sustainable degradation for several days, and enhanced antioxidant capability of the combined loaded component. In vivo studies revealed faster and superior wound healing, achieving nearly complete closure by day 21. Histopathology confirmed improved cell growth, tissue regeneration, collagen deposition, and neovascularization. It is believed that this multifunctional hydrogel-based wound dressing can be applied for effective burn wound treatment.

Chemical Compositions and Fumigation Effects of Essential Oils Derived from Cardamom, Elettaria cardamomum (L.) Maton, and Galangal, Alpinia galanga (L.) Willd, against Red Flour Beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae).

This study explores the use of essential oils from cardamom (Elettaria cardamomum (L.) Maton) and galangal (Alpinia galanga (L.) Willd) as alternatives to synthetic insecticides for controlling the red flour beetle, Tribolium castaneum (Herbst). The chemical compositions of these oils were analyzed using GC-MS, and their fumigation effects were tested in a vapor-phase bioassay. The experiment followed a factorial design with four types of essential oils, namely, those manually extracted from cardamom leaves (MCL) and galangal leaves (MGL) and those commercially produced from cardamom seeds (CCS) and galangal rhizomes (CGR), at seven concentrations (0, 50, 100, 150, 200, 250, and 300 µL/L air). The manually extracted oils yielded 0.6% from cardamom leaves and 0.25% from galangal leaves. MCL contained 28 components, with eucalyptol (25.2%) being the most abundant, while CCS had 34 components, primarily α-terpinyl acetate (46.1%) and eucalyptol (31.2%). MGL included 25 components, mainly caryophyllene (28.7%) and aciphyllene (18.3%), whereas CGR comprised 27 components, with methyl cis-cinnamate (47.3%) and safrole (19.8%) as the major constituents. The fumigation bioassay results revealed that CGR was the most effective, demonstrating the highest mortality rates of T. castaneum across all the tested periods and concentrations, achieving up to 96% mortality at 168 h with a concentration of 300 µL/L air. Statistical analyses showed significant differences in mortality based on the type and concentration of essential oil, particularly after 96 h. These findings highlight the potential of CGR, with its advantages and differences in chemical composition, as an effective biopesticide against T. castaneum, with increasing efficacy over time and at higher concentrations.

Host range and feeding preference of Basilepta fulvicornis (Jacoby) adult beetles in the Cardamom Hill Reserves, Kerala, India

Host range and feeding behavior of Basilepta fulvicornis (Jacoby) adult beetles were studied on different plant species (25 species from 18 genera and 13 families) in the Cardamom Hill Reserves, Kerala, India. Five new host plants of B. fulvicornis adult beetles, viz., Artocarpus hirsutus Lam., Ficus auriculata Lour., Anacardium occidentale L., Spondias mangifera Willd., and Terminalia chebula Retz., are reported for the first time. Non-preference and non-feeding of B. fulvicornis adults on the larval host, Elettaria cardamomum (L.) Maton was confirmed. Based on the feeding area, A. hirstus, F. auriculata, Mangifera indica and Artocarpus heterophyllus are the most preferred host species followed by Terminalia catappa, A. occidentale, S. mangifera, and T. chebula. Feeding preference and survival of adult beetles of B. fulvicornis on different tree species are indicated with a probable ecofriendly pest management solution.

The volatile constituents of rose, saffron and cardamom suppress the fibrillation of tau and not HEWL through the formation of non-toxic tau oligomers

The formation of fibrillar structures of tau is correlated with taupathies including Alzheimer's disease (AD). This study has aimed to find ways to prevent tau fibril formation. Here, we used dietary compounds including cinnamon (CN), damask rose (Rose), saffron (Saf) and green cardamom (Car), to evaluate the effects of their volatile constituents, on hen egg white lysozyme (HEWL), as a model protein (commonly used for fibrillation studies), as well as the brain-related tau protein. The study was done using different spectroscopic techniques as well as SDS-PAGE, AFM and MTT assay. While the results suggested that the volatile constituents were unable to prevent HEWL fibril formation, most of the dietary compounds, in particular Saf, Rose and Car, were able to interfere with the mature fibril formation, by either maintaining the native form of tau or resulting in the entrapment of non-toxic oligomeric forms of tau. Moreover, the neurotoxicity analysis of tau samples on neuroblastoma SH-SY5Y cells indicated that tau treated with Saf, Rose and Car were the least toxic. Overall, the findings indicate that the potential therapeutic impacts of the volatile constituents of Rose, Car and in particular Saf, may demonstrate significant efficacy in addressing neurodegenerative diseases such as AD.

In-vitro anthelmintic activity of crude extracts of Zingiberaceae species commonly available in Mwanza, Tanzania

Introduction: Resistance to commonly used anthelmintic drugs has been reported in many areas of the world. Natural products are good candidates for discovering more effective anthelmintic compounds. This study assessed the In-vitro activity of extracts from Curcuma longa, Zingiber officinale and Elettaria cardamomum. Methods: This study was an In-vitro experimental study involving Apporrectodea longa earthworms. The worms were treated with 20mls of both distilled water and ethanolic extracts of all plant species (at 20, 40 and 60mg/ml). Albendazole was used as a standard drug. Paralysis and death time were recorded. Results: The paralysis time for water extracts were 0.83 hrs, 1.22 hrs and 3.33 hrs at 20mg/ml for Elettaria cardamomum, Zingiber officinale and Curcuma longa respectively while death time was 2.00 hrs, 1.50 hrs and 7.61 hrs for Elettaria cardamomum, Zingiber officinale and Curcuma longa respectively. The paralysis time for ethanol extracts were 0.50 hrs, 0.58 hrs and 0.70 hrs at 20mg/ml for Elettaria cardamomum, Zingiber officinale and Curcuma longa respectively while death time was 1.00 hrs, 1.00 hrs and 1.64 hrs for Elettaria cardamomum, Zingiber officinale and Curcuma longa respectively. Elettaria cardamomum and Zingiber officinale recorded shorter paralysis time than albendazole at 20mg/ml. Conclusion: Zingiber officinale and Elettaria cardamomum have recorded promising In-vitro activity warranting for pharmacological and toxicological investigations.

Chemical characterization of Thymus zygis L. (thyme) and Elettaria cardamomum L. (cardamom) essential oils and investigation of their inhibitory potentials against cervicovaginal Escherichia coli isolates

IntroductionThe cervicovaginal microbiota plays a crucial role in women's well-being and reproductive health. This study initially focuses on identifying the chemical components of the essential oils (EOs) from Elettaria cardamomum L. (cardamom) (Ec) and Thymus zygis L. (thyme) (Tz). Subsequently, this study aims to determine the antimicrobial and biofilm inhibitory effects of these EOs against both cervicovaginal mixed cultures and the microbial strains isolated from them. MethodsThe compositions of EOs were determined by GC–MS analysis using an Agilent 7890B GC/5977A Series MSD System. Cervicovaginal samples were obtained from two women presenting complaints of a strong odor and vaginal discharge. Samples were collected from the cervix using a sterile cytobrush, ensuring no contact with the urethra, rectum, or external parts of the vagina. The cytological examination was conducted using Papanicolaou staining. Isolated microorganisms were identified through 16S Ribosomal RNA Gene Sequence Analysis and characterized using antibiogram tests. Antimicrobial tests of the EOs were performed by broth microdilution and disc diffusion methods. Biofilm formation was assessed using a crystal violet binding assay. ResultsThe major components of Ec EO were α-terpinyl acetate (41.95 %) and eucalyptol (28.58 %), whereas Tz EO contained significant amounts of o-cymene (38.76 %), carvacrol (22.66 %), and thymol (20.69 %). Escherichia coli codes OR651248 and OR651249 were isolated from CV 6 and CV 7 mixed cultures, respectively. E. coli OR651248 demonstrated a higher antibiotic resistance level than E. coli OR651249. Biofilm formation by mixed cultures was significantly higher than that by E. coli isolates (P < 0.05). The Ec EO displayed minimal to no effect against both mixed cultures, showing zero inhibition zone, 500 μL/mL minimum inhibitory concentrations (MICs), and 500 μL/mL minimum microbicidal concentrations (MMCs). However, the Tz EO exhibited antimicrobial activity against both mixed cultures and the E. coli isolates, with inhibition zones > 15 mm and MICs/MMCs < 4 μL/mL (P < 0.05). In all microbial cultures, 0.5 MIC of both EOs inhibited biofilm formation by more than 80 %. ConclusionThe Tz EO exhibits promising potential as an antimicrobial and biofilm inhibitory agent for managing cervicovaginal E. coli infections.

Antibacterial, Anti-inflammatory properties and Therapeutic Benefits of Cardamom (Elettaria cardamomum)

Cardamom (Elettaria cardamomum) is a conventional fragrant plant for which a few pharmacological properties have been related. In this consider, the antibacterial movement of two cardamom extricates (natural product and seeds), wealthy in unstable compounds, against major periodontal pathogens was assessed. In addition, the capacity of the extricates to apply anti-inflammatory action was tried. Both cardamom natural product and seed extricates applied an antibacterial impact against Aggregatibacter actinomycetemcomitans, Fusobacterium nucleatum, Porphyromonas gingivalis, and Prevotella intermedia (least inhibitory concentrations: 0.5% [v/v], 0.25%, 0.062%, 0.125%, individually and least bactericidal concentrations: 1%, 0.25%, 0.062%, 0.25%, individually). The cell film of P. gingivalis was disturbed by a treatment with cardamom extricates proposing the bactericidal mode of activity. The extricates moreover restrained biofilm arrangement in spite of the fact that it related with a development decrease. Besides, the cardamom extricates altogether diminished the emission of IL-1β, TNF- α, and IL-8 by lipopolysaccharide-stimulated macrophages. Prove were brought that the anti- inflammatory movement may result from restraint of the NF-κB signaling pathway. This ponder is the to begin with to give prove that cardamom natural product and seed extricates through their antibacterial and anti-inflammatory properties may be helpful specialists of intrigued against periodontal diseases.

Herbal Spices as Food and Medicine: Microscopic Authentication of Commercial Herbal Spices.

Herbal spices are an agricultural commodity, economically very important and beneficial in primary healthcare in the food and medicine sectors. Herbal spices are used as food flavoring agents as well as in phytotherapies throughout the world and have nutritive benefits. The food and medicine industries widely employ artificial or natural adulteration to retard the deterioration and utilization of these adulterants in food and medicine products has given rise to significant apprehension among consumers, primarily stemming from the potential health risks that they pose. Thus, their characterization for the purpose of identification, origin, and quality assurance is mandatory for safe human consumption. Here, we studied 22 samples of commonly traded herbal spices that belong to 20 different genera and 21 species comprising 14 families, investigated macroscopically or organoleptically as well as histologically under microscopic examination. In this study, we provide details on organoleptic features including appearance, taste, odor, color, shape, size, fractures, types of trichomes, and the presence of lenticels among the examined herbal spices and these features have great significance in the detection of both natural as well as artificial deterioration. In terms of microscopic characterization, each examined plant part comprising different anatomical characteristics has taxonomic importance and also provides useful information for authentication from natural adulterants. Furthermore, the studied taxa were also described with nutritive and therapeutic properties. For condiments, herbal beverages and medicinal purposes, different herbal parts such as leaves, floral buds, seeds, fruit, and accessory parts like mericarp, rhizome, bulbs, and bark were used and commercially traded. Similarly, in this study, the leaves of Cinnamomum tamala and Mentha spicata, the floral buds of Syzygium aromaticum, the seeds of Amomum subulatum, Brassica nigra, Punica granatum, Myristica fragrans, Phyllanthus emblica, and Elettaria cardamomum, the mericarp of Coriandrum sativum, and Cuminum cyminum were observed. As a result, we show the potential of herbal spices as a source of many valuable phytochemicals and essential nutrients for food, nutraceutical, and homoeopathic medicine.

Comparative Effects of Elettaria cardamomum Essential Oil and Its Nanoliposomal State on Mortality of Anopheles stephensi Larvae.

Malaria has remained the most dreadful vector-borne disease; hence, vector control is the most affordable and achievable approach to mitigate the disease burden. Due to the emergence of resistance and environmental pollution, herbal larvicides are considered an alternative to chemical types. Also, nanotechnology has been proposed as a promising solution to improve the efficiency of plant larvicides. This study aimed to develop an effective herbal larvicide. The chemical composition of Elettaria cardamomum essential oil (EO) was first investigated. Nanoliposomes containing the EO were then prepared using the ethanol injection method. After that, the larvicidal efficacy of the EO and its liposomal state were compared against Anopheles stephensi in laboratory conditions. Alpha-terpinyl acetate (77.59%), eucalyptol (4.38%), nerolidol (2.96%), linalool (1.77%), and limonene (1.69%) were the five major compounds of the EO. Nanoliposomes containing the EO with a particle size of 73±5 nm and a zeta potential of -16.3±0.8 mV were prepared. Additionally, the ATR-FTIR analysis verified the successful loading of the EO into nanoliposomes. The larvicidal activity of nanoliposomes exhibited remarkable potency, with an LC50 value of 14.35 (10-18) μg/mL, significantly more potent than the non-formulated EO, which had an LC50 value of 33.47 (28-39) μg/mL against Anopheles stephensi larvae. The nanoliposomes containing E. cardamomum EO showed promising efficacy against An. stephensi larvae. It could thus be considered for further application against other species of mosquitoes.
