Characteristics of Fast-Growing Wood Impregnated Using Monoethylene Glycol and SiO Nanoparticles Against Fungal Attacks

Jabon (Anthocephalus cadamba) and Sengon (Falcataria moluccana) were fast-growing wood species widely planted in the community forest. Both kinds of wood have low durability even though they can potentially be used in the carpentry material industry. Therefore, this research aimed to analyze the vacuum-pressure impregnation effect using monoethylene glycol (C2H6O2) or MEG and silica dioxide (SiO2) nanoparticles on wood resistance to fungal decay. The results showed that impregnation treatment with MEG and SiO2 nanoparticles significantly improved the durability of Jabon and Sengon against fungal attacks. Furthermore, MEGSiO2 with 24-hour polymerization had a better impact on durability compared to both the control and MEGSiO2 with 12-hour polymerization. The 24-hour polymerization using 1% SiO2 nanoparticles resulted in the lowest weight loss for Jabon (5.86% ) and Sengon (5.21%). In addition, the variation of SiO2 nanoparticle concentration did not significantly affect the weight loss and durability of Jabon and Sengon against fungal decay.

Comprehensive Secondary Metabolite Profiling and Antioxidant Activity of Aqueous and Ethanol Extracts of Neolamarckia cadamba (Roxb.) Bosser Fruits.

Neolamarckia cadamba (Rubiaceae) is a well-recognized medicinal plant with recorded therapeutical attributes. However, a thorough assessment of active compounds in its fruits is lacking, limiting their use and valorization in pharmacological industries. Thus, this study investigated variations in the fruits' secondary metabolite (SM) profiles, as well as antioxidant activities in aqueous (WA) and ethanol (ET) extracts. Liquid chromatography-electrospray ionization tandem mass spectrometry identified 541 SMs, of which 14 and 1 (di-O-glucosylquinic acid) were specifically detected in ET and WA, respectively. Phenolic acids (36.97%), flavonoids (28.10%), terpenoids (12.20%), and alkaloids (9.98%) were the dominant SMs. The SM profiles of the fruits in WA and ET were quite different. We revealed 198 differentially extracted (DE) metabolites between WA and ET, including 62 flavonoids, 57 phenolic acids, 45 terpenoids, 14 alkaloids, etc. Most DE flavones (36 out of 40), terpenoids (45 out of 45), and alkaloids (12 out of 14) had higher content in ET. Catechin and its derivatives, procyanidins, and tannins had higher content in WA. ABTS and DPPH assays showed that the antioxidant activity of ET was significantly higher than that of WA. Our findings will facilitate the efficient extraction and evaluation of specific active compounds in N. cadamba.

Extraction of polysaccharide fraction from cadamba (Neolamarckia cadamba) fruits and evaluation of its in vitro and in vivo antioxidant activities

In this study, polysaccharide fraction (PFFNC) derived from Neolamarckia cadamba fruits showed remarkable antioxidant activity. The PFFNC was successfully extracted from the fruits by the hot water extraction process, followed by decolorization, defatting, and deproteinization. The chemical composition of PFFNC was effectively characterized by the use of UV–Vis, FT-IR, CHN, GC–MS, and 13C NMR spectroscopy. The findings indicated that PFFNC had an average molecular weight of 292 kDa and was predominantly composed of carbohydrates (76 %), with notable contributions from uronic acids (37.22 %) and proteins (12.35 %). The primary components of the sugar content were glucose (19.24 %), galactose (10.19 %), mannose (4.09 %), and glucuronic acid (2.8 %). The tertiary structural study verified the existence of a triple-helical structure. PFFNC exhibited a strong reducing power in vitro as determined by ABTS (IC50: 121 ± 0.12 μg/mL), DPPH (IC50: 146.065 ± 0.54 μg/mL), FRAP (677.788 ± 24.189 mM Fe (II)/g), hydroxyl radical scavenging (IC50: 78.736 ± 0.32 μg/mL), and phosphomolybdate assay (90.7 ± 0.43 mg AAE/g). In addition, the PFFNC furthermore showed significant in vivo antioxidant capacity, as determined using the brine shrimp (Bsmp) (Artemia salina Leach) model. The PFFNC exhibits significant antioxidant potential, suggesting broad spectrum applications in pharmaceuticals, nutraceuticals, and oxidative stress-related disorders.

Preparation and evaluation of liposomal gel containing Neolamarckia cadamba leaves extract for anti-inflammatory activity

The objective of present research work is to develop liposomes as a carrier system for methanolic extract, its incorporation in to gel formulations and to characterize the prepared and develop liposomal gel formulation. Formulation was carried out by thin film technique. Scanning electron micrograph of the prepared nanosponges at 50.00 kx magnification showed that the liposome was porous with a smooth surface morphology and spherical shape. The porous nature of liposome was clearly observed in the SEM images. Particle size and zeta potential was determined by Malvern Zeta sizer. The particle size analysis confirmed that the prepared sample were in the nanometer range. Average particle size obtained for the formulations F1 to F5 were 162.7 nm to 195.6 nm. Zeta potential values of liposome indicated that the formulated liposomes are stable. The amount of drug being entrapped in liposome was calculated and all the prepared liposome was found to possess very high entrapment efficiency. The viscosity of liposome loaded gel is found to 6842±0.32cps. The pH of liposome loaded gel is 6.3 and spreadability is 12.11, indicating that liposome loaded gel has high release and permeability. The in vitro anti-inflammatory effect of Neolamarckia cadamba extract was evaluated against denaturation of egg albumin. The present findings exhibited a concentration dependent inhibition of protein (albumin) denaturation by Neolamarckia cadamba throughout the concentration range of 20-100μg/ml. Diclofenac sodium (at the concentration range of 20-100 μg/ml) was used as reference drug which also exhibited concentration dependent inhibition of protein denaturation; however, the effect of diclofenac sodium was found to be less active when compared with extract name. Moreover, the results demonstrated that the liposome-based drug delivery approach could be a valuable tool to improve the therapeutic efficacy of phytochemicals by improving their absorption, and bioavailability via altering their physicochemical and release properties. Keywords: Liposomes, Neolamarckia cadamba, Qualitative phytochemical screening, Thin film technique, In vitro anti-inflammatory activity.

In vitro shoot regeneration system from leaves wrapped by bud scales of a multipurpose tree (Neolamarckia cadamba)

Neolamarckia cadamba (N. cadamba) is an evergreen tree species known for its rapid growth, remarkable wood properties, and significant value in medicine, feeding, and landscape. In order to clone a N. cadamba individual with excellent genotype, a plant regeneration protocol was successfully established with leaves wrapped by bud scales as explants. The optimal sterilization method for the leaves was 0.1% Mercury Chloride (HgCl2) treatment for 1 min before culturing on Murashige and Skoog’s medium (MS) supplemented with 3.0 mg/L Thidiazuron (TDZ), 0.1 mg/L 2–4 Dichlorophenoxyacetic acid (2-4D), 0.05 mg/L α-Naphthaleneacetic acid (NAA) and 1 mL/L Plant Preservative Mixture (PPM) to induce calluses. The medium containing 1 mL/L PPM could effectively inhibit explant contamination without an unfavorable impact on the final induction rate of callus from the leaves. Three types of calluses were induced from the leaves cultured on the above medium. Among them, only the Type II callus, which was green and nodular, had few particle masses, could differentiate into adventitious shoots on the MS medium supplemented with 1.5 mg/L 6–Benzylaminopurine (6-BA) and 0.05 mg/L NAA, with the induction rate of 78.89% and adventitious shoot number per callus of 11.67. The adventitious shoots were proliferated on the MS medium supplemented with 1.0 mg/L 6-BA and 0.05 mg/L Indole-3- butyric acid (IBA) with the proliferation coefficient of 3.37. And the micro-shoots developed roots in the MS medium supplemented with 0.05 mg/L NAA and 0.05 mg/L IBA. The regeneration protocol can be used in the propagation and large scale production of seedlings with the same genotype as an excellent individual of N. cadamba in the field.

Seasonal variations in soil characteristics control microbial respiration and carbon use under tree plantations in the middle gangetic region

Seasonal variations directly impact the biochemical and microbial properties of the soil, influence carbon and nutrient cycling within the soil system. Soils under tree plantation (TP) are rich in organic matter and microbial population, making them more susceptible to seasonal variation. We studied the effect of seasonal variations in soil chemical properties (pH, electrical conductivity (EC), total organic carbon (TOC), total nitrogen (TN), C/N ratio etc) and microclimate (moisture and temperature) on microbial respiration (SR), biomass, and carbon (C) utilization efficiency under 13 years old Kadamb (Anthocephalus cadamba Miq.), Simaraubha (Simarouba glauca DC), and Litchi (Litchi chinensis Sonn.) based TPs in middle Gangetic region. In contrast to higher SR and metabolic quotient (qCO2) in winter, the microbial biomass carbon (MBC) and microbial biomass nitrogen (MBN) in fall > summer > spring > winter, irrespective of TPs. The positive relationship between qCO2 and C/N ratios strongly supports the dependence of microbes on soil carbon for respiration. qCO2 had a significantly positive relationship with soil moisture (MC) and Electrical conductivity (EC), but a significantly negative relationship with temperature and pH. Higher MBN/TN and MBC/TOC ratios fall under simaraubha, and litchi-based TPs indicated more nitrogen (N) and carbon accumulation into microbial biomass. The seasonal variation of MBC/MBN ratios signifies the changes in microbial communities and fungi dominate over bacteria during winter, as bacteria have a lower C/N ratio than fungi. Stepwise regression analysis suggested that soil properties and micro-climate regulated microbial biomass and SR differ with TPs. Thus, the study indicates that microbial activities and biomass production can significantly influence by soil properties and seasonal variations under TPs.

Allometric equation of Paraserianthes falcataria (L.) and Anthocephalus cadamba Miq. for estimating carbon stocks

Coal mining can increase land degradation and deforestation, so efforts are needed to ensure land use in post-mining areas. Therefore, mining companies must carry out land reclamation to restore the important function of forests by planting sengon laut (Paraserianthes falcataria (L.)) and burflower tree (Anthocephalus cadamba Miq.). In contrast to mining, which produces emissions and carbon that contribute to global warming, land reclamation helps absorb carbon and produce oxygen for living things. Therefore, a study was carried out to estimate the carbon stocks from reclamation activities at PT. Indobara Borneo. A quantitative approach through Stratified Random Sampling was applied in this study. Carbon estimation is carried out using allometric equations. The allometric equation of Paraserianthes falcataria (L.) is Y = 0.028D2,695, while the allometric equation of Anthocephalus cadamba Miq. is Y = 0.035D2,600. The total carbon stocks for burflower tree plants are 84.51 tons/ha with a CO2 sink potential of 974.73 tons/Ha, while the total carbon stocks for sengon laut plants are 86.18 tons/ha with a CO2 sink potential of 1355.49 tons/ha. The value of CO₂ sink and carbon stock indicates that there are environmental services to restore and improve vegetation.

Evaluating the electrochemical boost and antimicrobial power of biogenic zinc oxide-polyaniline nanocomposite

Bio-based materials from bark, wood, leaves, and fruits have several uses in nanotechnology. Anthocephalus Cadamba is a biological reducing agent in nanocomposites. The fruit of Anthocephalus Cadamba is used to synthesize ZnO nanoparticles and polyaniline to make a ZnO-PANI nanocomposite. We describe UV–visible, FTIR, XRD, and SEM data to support synthesis. The dielectric constant is highest in the ZnO-PANI nanocomposite compared to pure ZnO nanoparticles. The Nyquist plot semicircular arc confirms temperature-induced conductivity improvement in nanocomposites. Nanocomposites have 1.3 ×10−2 S/m higher conductivity than nanoparticles. The ZnO-PANI nanocomposite has the greatest specific capacitance (Csp) of 1.3 × 10−2. This work suggests that ZnO-PANI nanocomposite electrodes might be useful supercapacitors in energy storage devices with antibacterial properties. XTT assay and biofilm formation assay using CLSM (Confocal laser scanning microscope) indicated that Integration of ZnO-PANI nanocomposites onto biofilm-prone surfaces like medical devices or implants inhibited bacteria adhesion and biofilm growth in antimicrobial investigations.

Extracting insoluble dietary fiber from Kadam fruit (Neolamarckia cadamba) and its characterization

Extracting insoluble dietary fiber from Kadam fruit (Neolamarckia cadamba) and its characterization

Effects of Dietary Bacillus amyloliquefaciens SCAU-070 (Based on a Woody Plant-Based Diet) on Antioxidation, Immune and Intestinal Microbiota of Tilapia (Oreochromis niloticus).

This study aimed to explore the effects of Bacillus amyloliquefaciens (BA) as one woody forage addition (as a probiotic, 1 × 107 CFU/g) on tilapia (Oreochromis niloticus). Woody forage is one kind of fishery feed that could significantly enhance the growth, feed utilization, and digestibility of tilapia. At first, tilapia was divided into eight groups and fed with control, control + BA, Moringa oleifera, M. oleifera + BA, Neolamarckia cadamba, N. cadamba + BA, Broussonetia papyrifera, and B. papyrifera + BA diets, respectively. After dieting for 8 weeks, the intestinal morphology of tilapia in the eight groups was observed, and the effects of the B. amyloliquefaciens addition and wordy forage on the intestine functions were analyzed by two-way ANOVA. As no significant negative effects were found on the woody forage on tilapia, the villus height, density and width, and epithelial goblet cells in the posterior intestines of tilapia with BA supplementation were greater than those in the groups without BA supplementation, suggesting B. amyloliquefaciens SCAU-070 could promote the growth and development of tilapia intestinal tracts. Furthermore, it was found that B. amyloliquefaciens SCAU-070 enhanced the antioxidation capacity of tilapia posterior intestine tissue by promoting the activity of superoxide dismutase and content of malondialdehyde. In addition, the result of high-throughput sequencing (16S rDNA) showed that the beneficial bacteria Cetobacterium and Romboutsia in the probiotic groups increased significantly, while the potential pathogenic bacteria Acinetobacter decreased significantly.

Mechanical properties of jabon (Neolamarckia cadamba (Roxb.) Bosser) wood 13 years old and its potential utilization as a structural material

Jabon (Neolamarckia cadamba (Roxb.) Bosser) is a type of fast-growing tree that is expected to meet the national demand for wood because it has fast-growing properties. This study’s objective was to examine the mechanical properties of 13 years old jabon wood based on its position in the stem. The preparation of mechanical properties test samples and their tests refer to the British Standard (BS) 373 Methods of testing small clear specimens of timber and the American Society for Testing and Materials (ASTM) D143 Standard test method for small clear specimens of timber. Based on the results of the study, the stem parts (bottom, middle, and top) had no significant effect on the mechanical properties of wood except for the compressive strength parallel to the grain and hardness. In general, the mechanical properties showed an increase from the bottom to the top of the stem and from the pith toward the bark, although there were some differences. The mechanical properties of jabon wood obtained from this study generally showed higher values than jabon wood used in other studies with younger ages, although in general, it did not change the category of jabon wood from strength class III-IV. However, its use as a structural material would be more profitable than using a younger age of jabon wood, as it is usually harvested so far.

Species selection in unfamiliar terrain: participants’ preferences and practices around Mount Elgon, Uganda

Efforts to restore the world forests and trees are obviously significant and still increasing. Selection of tree species in this context is based on prevailing challenges impacting on livelihood needs. A study was conducted around Mount Elgon between January 2018 and July 2020. The objectives were to; i) document the socio-economic factors of participants in tree multiplication and planting, ii) identify the farmers practices and choice of species used under farming contexts iii) assess the relationship between the participants socio-economic factors, practices and choices of tree species. A multi-stage sampling approach was followed to select a total of 150 participants. The participants were engaged through semi-structured and key informant interviews. Quantitative data were analyzed in MINITAB 19. Results show that tree multiplication and planting activities were dominated (84%) by a vibrant group of males between the ages of 15 and 40 years old. Up to 60% of this group were illiterate or inexperienced in tree planting and multiplication. Exotic trees (containing Eucalyptus grandis, Grevillea robusta and Neolamarckia cadamba) were highly valued for firewood, timber and small stems used to support food crops including Musa spp., Phaseolus vulgaris and Solanum lycopersicum. The indigenous species (mainly Cordia africana, Maesopsis eminii, Albizia spp. and Ficus spp.) were on the other hand treasured for shade in the coffee-banana farming systems as well as serving social-cultural benefits, counting medicine and rituals. The participants gender significantly influenced the choice of tree species adopted (P<0.001). For example, the men were more interested in timber and carbon related tree species while the women and the youths were generally involved in apiculture and fruit tree growing. With all the anticipated benefits and publicity about the exotic trees in this region, the participants have no choice but to follow the advice from the various tree planting campaigns. We recommend co-operation of the stakeholders especially during tree germplasm selection in order to meet performance expectations. The expectations include developing individual species breeding protocols based on site conditions for tree seed collection, seedling multiplication and planting.

Wound healing, antidiabetic and antioxidant activity of Neolamarckia cadamba, quercetin rich, extract

IntroductionTraditional Chinese Medicine (TCM), Neolamarckia cadamba (NMCA), a member of the Rubiaceae family, is well-known for its rich assortment of phytochemicals and has a historical use in addressing various health issues. Quercetin is a bioactive compound that is widely used in botanical medicine and TCM because of its potent antioxidant activity. This study aimed to assess HPTLC analysis and explore the wound healing, antidiabetic, and antioxidant properties of optimized extracts from NMCA stems and bark. The objective of this study was to analyze the metabolites present in the plant and their potential health-related benefits. MethodsThe phytoconstituents in NMCA were identified by HPTLC analysis of its ethanolic extracts. The antioxidant activity was assessed using ABTS+ and DPPH assays. Furthermore, potential antidiabetic effects were investigated using inhibition assays targeting α-amylase and α-glucosidase. In addition, the evaluation included an MTT assay (HaCaT cell line) for cell viability and a wound healing scratch assay for cell migration. ResultThe ethanolic extract of NMCA was subjected to phytochemical analysis, which revealed the presence of diverse phytoconstituents, including alkaloids, flavonoid phenols, saponins, steroids, glycosides, and tannins. Subsequent HPTLC analysis confirmed the presence of quercetin in the extract. However, the MTT assay indicated the (IC50 313.3 ± 0.091 µg/ml) for NMCA plant extract. The wound healing scratch assay demonstrated significant cell migration. Notably, the ethanolic extract displayed significant antioxidant and antidiabetic activities in a dose-dependent manner. The antioxidant potential was evident in the ABTS+ radical scavenging assay (41.168 %) and DPPH radical scavenging assay, with an (IC50 185.275 µg/mL). Antidiabetic effects were demonstrated through the inhibition of α-amylase (IC50 37.23 ± 1.49 μM) and α-glucosidase (IC50 38.26 ± 1.72 μM). Comparatively, the standard acarbose exhibited (IC50 38.94 ± 0.45 μM) for α-glucosidase and (IC50 34.61 ± 3.71 μM) for α-amylase. Furthermore, the ethanolic extract of NMCA, which is rich in phytoconstituents and quercetin, displayed potent wound healing and antidiabetic and antioxidant properties, suggesting its potential therapeutic significance. DiscussionThese results further corroborate the longstanding medicinal use of NMCA, suggesting its therapeutic potential in addressing wound healing, oxidative stress, and diabetes mellitus.

Characterization of lipophilic extractives in the wood of anthocephalus cadamba and anthocepalus macrophyllus from progeny trial

This study aims to determine the lipophilic component that affects the quality of pulp and paper products in wood of 10-year-old Anthocephalus cadamba (families 23, 11 and 6) and 5-year-old Anthocepalus macrophyllus (families 75, 85 and 2). The results showed that the main group of compounds that appeared frequently and were identified in the lipophilic fraction were fatty acids (palmitic, oleic, linoleic and stearic acids), fatty alcohols (eicosanol, heneicosanol and tetracosanol), sterols (β-sitosterol and campasterol), hydrocarbons (hexadecane, tricosene and cyclotetracosane), aldehydes, alongside minor amounts of triterpenoid. F11 and F2 can be promoted as raw materials for pulp and paper, while F6 and F75 are not recommended because of the high levels of lipids such as sterols, triterpenoids, hydrocarbons, fatty acids, and fatty alcohols.

Chemical Profiling and Biological Activities on Nepalese Medicinal Plant Extracts and Isolation of Active Fraction of Nyctanthes arbor-tristis.

The importance of medicinal plants for the treatment of different diseases is high from the aspects of the pharmaceutical industry and traditional healers. The present study involves nine different medicinal plants, namely, Neolamarckia cadamba, Nyctanthes arbor-tristis, Pogostemon benghalensis, Equisetum debile, Litsea monopetala, Spilanthes uliginosa, Desmostachya bipinnata, Mallotus philippensis, and Phoenix humilis, collected from Chitwan district of Nepal for biochemical analysis followed by the isolation of active plant fractions from the bioactive plant extract. The methanolic extracts of roots, barks, seeds, seed cover, and the other aerial parts of plants were used for the phytochemical analysis and biological activities. The DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical scavenging assay was adopted to evaluate the antioxidant activity. Antibacterial activity was evaluated using the agar well diffusion method. The antidiabetic activity was studied by the α-amylase enzyme inhibition assay. The highest antioxidant activity was observed in extracts of Nyctanthes arbor-tristis followed by Mallotus philippensis (seed cover), Pogostemon benghalensis, Litsea monopetala, Phoenix humilis, and Neolamarckia cadamba with IC50 values of 27.38 ± 1.35, 32.08 ± 2.81, 32.75 ± 2.13, 33.82 ± 1.07, 40.14 ± 0.93, and 50.44 ± 3.75 µg/mL, respectively. The highest antidiabetic activity was observed in extracts of Phoenix humilis followed by Desmostachya bipinnata and Pogostemon benghalensis with IC50 values of 95.69 ± 6.97, 99.24 ± 12.6, and 106.3 ± 12.89 µg/mL, respectively. The mild α-amylase enzyme inhibition was found in extracts of Nyctanthes arbor-tristis, Spilanthes uliginosa Swartz, Litsea monopetala, and Equisetum debile showing IC50 values of 110.4 ± 7.78, 115.98 ± 10.24, 149.83 ± 8.3, and 196.45 ± 6.04 µg/mL, whereas Mallotus Philippensis (seed cover), Mallotus philippensis (seed), and Desmostachya bipinnata showed weak α-amylase inhibition with IC50 values of 208.87 ± 1.76, 215.41 ± 2.09, and 238.89 ± 9.27 µg/mL, respectively. The extract of Nyctanthes arbor-tristis showed high zones of inhibition against S. aureus (ATCC 25923) and E. coli (ATCC 25922) of ZOI 26 and 22 mm, respectively. The chemical constituents isolated from the active plant Nyctanthes arbor-tristis were subjected to GCMS analysis where the major chemical compounds were 11,14,17-eicosatrienoic acid and methyl ester. These results support the partial scientific validation for the traditional uses of these medicinal plants in the treatment of diabetes and infectious diseases by the people living in different communities of Chitwan, Nepal.

The potential of dark septate endhophyte fungus from white jabon (Neolamarckia cadamba (Roxb.) Bosser)

Endophytic fungi are one of the forest microbes that can be solutions for increasing the resistance of forest plants to environmental stress. Exploration and collection of endophytic fungi from the forest is important because the condition of the forest as a natural habitat for microbes has been disturbed due to degradation and deforestation. A potential plant species for forest and land rehabilitation is white jabon (Neolamarckia cadamba (Roxb.) Bosser). The research objective was to isolate and characterize endophytic fungi and to obtain the dark septate endhophyte from the roots of the white jabon which have the potential to increase plant growth. The fungus was isolated by surface sterilization method and then characterized and identified morphologically. Pathogenicity test was carried out to determine the pathogenicity of the fungus. The results of the study found ten isolates. Most of the isolated fungi showed sterile mycelia with septate hyphae, so they were not identified morphologically. The isolate of CPGS 3 isolates probably belonged to the genus Aureobasidium sp. CPGS 3, CPKR 6, and CPPS 11 isolates are candidates for dark septate endophyte fungi which have the potential to promote plant growth and not become pathogens in chinese cabbage (Brassica rapa).

HPTLC Phytochemical Profiling and Simultaneous Quantification of Quercetin and Gallic acid in Neolamarckia cadamba (Roxb.)

HPTLC analysis of Neolamarckia cadamba (Roxb.) Bosser commonly known as kadamb reveals presence of several bioactive compounds along with percentage of quercetin and gallic acid in the methanolic extract of test samples. Quantification of markers (quercetin and gallic acid) along with phytochemical profiling of Neolamarckia cadamba was done at 254nm and 366nm wavelength through HPTLC CAMAG scanner III. Quantification was done by using peak area and peak height. Chromatograms and tracks obtained reveals that the test samples, sample 1 and sample 2 have quercetin 1.29% and 0.77% respectively. Phytochemical profiling of sample 1 and sample 2 reveals presence of 16 and 10 unknown bioactive compounds respectively denoted by the number of peaks present in chromatograms. As this study acknowledging phytochemical profiling, quantification of quercetin and gallic acid will be accountable for further research towards pharmacognostic and therapeutic value of Neolamarckia cadamba.

Effects of Neolamarckia cadamba leaves extract on microbial community and antibiotic resistance genes in cecal contents and feces of broilers challenged with lipopolysaccharides.

The effects of Neolamarckia cadamba leaves extract (NCLE), with effective ingredients of flavonoids, on antibiotic resistance genes (ARGs) and relevant microorganisms in cecal contents and feces of broilers treated with or without lipopolysaccharide stimulation (LPS) were investigated. LPS stimulation increased (P < 0.05) the relative abundance of ARGs and mobile genetic elements (MGEs), such as tet(W/N/W), APH(3')-IIIa, ErmB, tet (44), ANT (6)-Ia, tet(O), tet (32), Vang_ACT_CHL, myrA, ANT (6)-Ib, IncQ1, tniB, and rep2 in cecal contents. However, the difference disappeared (P > 0.05) when NCLE was added at the same time. These differential ARGs and MGEs were mainly correlated (P < 0.01) with Clostridiales bacterium, Lachnospiraceae bacterium, and Candidatus Woodwardibium gallinarum. These species increased in LPS-stimulated broilers and decreased when NCLE was applied at the same time. In feces, LPS stimulation decreased (P < 0.05) the relative abundance of tet(Q), adeF, ErmF, Mef(En2), OXA-347, tet (40), npmA, tmrB, CfxA3, and ISCrsp1, while the LPS + NCLE treated group showed no significant effect (P > 0.05) on these ARGs. These differential ARGs and MGEs in feces were mainly correlated (P < 0.01) with Clostridiales bacterium, Pseudoflavonifractor sp. An184, Flavonifractor sp. An10, Ruminococcaceae bacterium, etc. These species increased in LPS-stimulated broilers and increased when NCLE was applied at the same time. In conclusion, LPS stimulation and NCLE influenced microbial communities and associated ARGs in both cecal contents and feces of broilers. NCLE alleviated the change of ARGs and MGEs in LPS-induced broilers by maintaining the microbial balance.IMPORTANCEAntibiotics showed a positive effect on gut health regulation and growth performance improvement in livestock breeding, but the antimicrobial resistance threat and environment pollution problem are increasingly severe with antibiotics abuse. As alternatives, plant extract containing bioactive substances are increasingly used to improve immunity and promote productivity. However, little is known about their effects on diversity and abundance of ARGs. Here, we investigated the effects of NCLE, with effective ingredients of flavonoids, on ARGs and relevant microorganisms in cecal contents and feces of broilers treated with or without lipopolysaccharide stimulation. We found that NCLE reduced the abundance of ARGs in cecal contents of lipopolysaccharide-induced broilers by maintaining the microbial balance. This study provides a comprehensive view of cecal and fecal microbial community, ARGs, and MGEs of broiler following LPS stimulation and NCLE treatment. It might be used to understand and control ARGs dissemination in livestock production.

Pemanfaatan Limbah Kayu Ulin (Eusideroxylon zwageri) sebagai Bahan Pengawet untuk Mencegah Serangan Rayap Kayu Kering pada Kayu Jabon (Anthocephalus cadamba)

Eusideroxylon zwageri wood is a type of wood wich have high natural durability that contains extractive compounds such as alkaloids, tannins, saponins, flavonoids, and phenolics that are toxic to wood-destroying organisms. The ironwood sawmill industry produces waste in the form of sawdust that has not been used but only disposed of into the environment. Therefore, that wood sawdust waste can be used as a natural wood preservative to preserve wood whish have low natural durability such as Anthocephalus cadamba. In this study, A. cadamba wood preservation was carried out with irondust extract with various solution formulas, namely 5%, 10%. 15% and 20%. The purpose of this study was to know the effect of irondust extract solution formula as a preservative on the results of jabon wood preservation which includes absorption and retention of preservatives, mortality of dry wood termites, and the percentage of weight reduction of test samples after being fed to dry wood termites. The results of this research showed that the irondust extract solution formula had a significant effect on the absorption and retention of preservatives and the mortality of dry wood termites. The 20% irondust extract solution formula resulted in a higher preservative retention and drywood termite mortality value than the 5%, 10% and 15% solution formula, which was 12.13 Kg/m3 for retention and 88% for drywood termite mortality.

Insights into the mechanisms of diabetic wounds: pathophysiology, molecular targets, and treatment strategies through conventional and alternative therapies.

Diabetes mellitus is a prevalent cause of mortality worldwide and can lead to several secondary issues, including DWs, which are caused by hyperglycemia, diabetic neuropathy, anemia, and ischemia. Roughly 15% of diabetic patient's experience complications related to DWs, with 25% at risk of lower limb amputations. A conventional management protocol is currently used for treating diabetic foot syndrome, which involves therapy using various substances, such as bFGF, pDGF, VEGF, EGF, IGF-I, TGF-β, skin substitutes, cytokine stimulators, cytokine inhibitors, MMPs inhibitors, gene and stem cell therapies, ECM, and angiogenesis stimulators. The protocol also includes wound cleaning, laser therapy, antibiotics, skin substitutes, HOTC therapy, and removing dead tissue. It has been observed that treatment with numerous plants and their active constituents, including Globularia Arabica, Rhus coriaria L., Neolamarckia cadamba, Olea europaea, Salvia kronenburgii, Moringa oleifera, Syzygium aromaticum, Combretum molle, and Myrtus communis, has been found to promote wound healing, reduce inflammation, stimulate angiogenesis, and cytokines production, increase growth factors production, promote keratinocyte production, and encourage fibroblast proliferation. These therapies may also reduce the need for amputations. However, there is still limited information on how to prevent and manage DWs, and further research is needed to fully understand the role of alternative treatments in managing complications of DWs. The conventional management protocol for treating diabetic foot syndrome can be expensive and may cause adverse side effects. Alternative therapies, such as medicinal plants and green synthesis of nano-formulations, may provide efficient and affordable treatments for DWs.
