Abstract
Species belonging to the genus Pseudomonas is a rod shaped Gram-negative bacteria emerged as an important silkworm pathogen with broad-level multi-drug resistance. The extensive usage of antimicrobials in sericulture farming is gradually leading to the emergence of multi-drug resistance (MDR) strains, posing a significant threat to the well-being of both Bombyx mori L. and serifarmers. Pseudomonas spp. with MDR level may gets transmitted from the infected silkworm to human handlers either via direct contact or through contaminated feces. To understand the emerging concern of antimicrobial resistance (AMR) in Pseudomonas spp. provides insights into their genomic information. Here, we present the draft genome sequence data of Pseudomonas sp. strain RAC1 isolated from a flacherie infected Nistari race of Bombyx mori L. from the silkworm rearing house of Raiganj University, India and sequenced using the Illumina NovaSeq 6000 platform. The estimated genome size of the strain was 4494347 bp with a G + C content of 63.5%. The de novo assembly of the genome generated 38 contigs with an N50 of 200 kb. Our data might help to reveal the genetic diversity, underlying mechanisms of AMR and virulence potential of Pseudomonas spp. This draft-genome shotgun project has been deposited under the NCBI GenBank accession number NZ_JAUTXS000000000.

Abstract
The plant Acalypha indica L. is a well-known traditional plant belonging to the family Euphorbiaceae. Traditional practices of the plant claim to treat asthma, pneumonia, wound healing, rheumatoid arthritis, bronchitis, and skin disorders. The major phytochemicals reported are cyanogenic glucosides, tannins, coumarins, flavonoid glycosides, fatty acids, and volatile oils. To summarize the anti-inflammatory potential of Acalypha indica extract and its phytochemicals through preclinical studies. The search terms include anti-inflammatory, Acalypha indica, and Acalypha indica extract independently or in combination with pro-inflammatory markers using various databases, including Scopus, Web of Science, PubMed, ProQuest, and Google Scholar. The results of preclinical studies confirm that Acalypha indica exhibits strong anti-inflammatory activity. Most of the experimental studies that have been conducted on plant extract are protein denaturation, human red blood cell membrane stabilization assay, and carrageenan-induced inflammation models. However, the molecular mechanism in these studies is still unclear to demonstrate its anti-inflammatory effects. Acalypha indica possesses anti-inflammatory effects that may be due to the presence of phenolic compounds especially flavonoids present in the Acalypha indica. Thus, further research is needed, to understand mechanistic insights of the plant phytochemicals to represent anti-inflammatory properties.

Abstract
The study of community composition and community structure is important to know the ecological behaviour and community dynamics of the participating species and to understand the molecular interplay that lies between them. The community diversity greatly lies in the physiological status of the host and the environmental factors. The present study aims to explore the endophytic bacterial communities and their dynamics in the pre-flowering and post-flowering seasons in the horticulturally important Mango (Mangifera indica L.) and its hemiparasites: Loranthus parasiticus (L.) Marr. and Macrosolen colchinchinensis (Lour.) Tiegh. through a metagenomic approach using the sequence of V3 region of 16S rRNA gene. The genera Bacillus, Acinetobacter and Corynebacterium, under the phyla Firmicutes, Proteobacteria and Actinobacteria, respectively, were found to be the most abundant genera present in mango and its hemiparasites. It was found that during the post-flowering season, the twigs and leaves of mango had lesser endophytes than in other seasons while the alpha-diversity indices of the representative genera were the highest in L. parasiticus during the same seasons. However, in M. colchinchinensis, the alpha diversity was also higher in the post-flowering season similar to another hemiparasite plant L. parasiticus. The ecological, taxonomic and complex correlation studies unravelled that the hemiparasites act as the potent reservoirs of endophytic communities throughout the year and during favourable conditions, these bacterial communities disseminate to the mango plant.

Abstract
Mycorrhizae association is reported to enhance the survivability of the host plant under adverse environmental conditions. The present study aims to explore the mycorrhizal association in the roots of different ecotypes of a threatened medicinal plant, Clerodendrum indicum (L.) O. Kuntze (Verbenaceae), collected from W.B., India, which correlates the degree of root colonization to the nutritional status of the native soil. Ten ecotypes of C. indicum having diverse morphological variations were collected. The mycorrhizae were characterized by both morphological and molecular methods. The nutritional status of the native soils was estimated. The study revealed that all the ecotypes have an association with mycorrhizal forms like hyphae, arbuscules, and vesicles. The molecular analysis showed Glomus intraradices and Rhizophagus irregularis as the associated arbuscular mycorrhizal fungi (AMF). A significant variation in arbuscule and vesicle formation was found growing in the varied nutritional statuses concerning soil parameters. The arbuscule was found negatively correlated with pH, conductivity, and potassium and positively correlated with organic carbon, nitrogen, and phosphorus. The vesicle was found positively correlated with pH, organic carbon, and potassium and negatively correlated with conductivity, nitrogen, and phosphorus. The interaction between conductivity: nitrogen, conductivity: phosphorus, organic-carbon: nitrogen, and pH: conductivity was significant in influencing vesicle formation. However, none of the interactions between parameters was found significant in influencing arbuscule formation. Thus, the study concludes that G. intraradices and R. irregularis are the principle mycorrhizae forming the symbiotic association with the threatened medicinal plant, C. indicum. They form vesicles and arbuscules based on their soil nutritive factors. Therefore, a large-scale propagation through a selective AMF association would help in the conservation of this threatened species from extinction.

Abstract
Using molecular docking and other studies, 20 compounds extracted from Monochoria hastata (L.) Solms were screened, and their inhibitory efficiency examined against main protease (3CLpro) of SARS CoV-2. All the compounds were found to binding with 3CLpro through van der Waals and electrostatic forces of attractions. Among them, Azelaic dihydrazide (ADZ) was found to have the highest docking score. 3CLpro-ADZ complex was studied by MD simulation. ADZ was found to disrupt the structure of 3CLpro after 2 ns. RMSD and RMSF analysis along with sequence and binding energy analysis suggest that ADZ can be a potential drug against SARS CoV-2.

Abstract
Monochoria hastata (L.) Solms (family Pontederiaceae), an ethnomedicinal aquatic herb, is used to remedy several gastrointestinal diseases by various ethnic groups in India. The present study aimed to purify and characterize the antibacterial active ingredient against gastrointestinal (GI) diseases and its mode of action using in vitro experimental models. The active lead molecule in the ethyl acetate extract (EA-Mh) fraction has been purified and characterized through high-performance liquid chromatography (HPLC), proton nuclear magnetic resonance (1H NMR), and electrospray ionization mass spectrometry (ESI-MS) methods. The anti-enteric efficacy has been evaluated against enteropathogenic Gram-positive and Gram-negative bacteria by minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), lactate dehydrogenase (LDH), and scanning electron microscopy (SEM) studies. The synergistic and antagonistic studies were done on E. coli MTCC 723 using standard antibiotics (ampicillin and kanamycin, final conc. 50 µg/ml) in a sterilized 96-well micro-plate, incubated at 37 ℃ for 24 h. The chromatographic and spectroscopic analyses revealed the presence of tridecanoic acid methyl ester (TAME) in the bioactive fraction. The compound causes significant extracellular leakage activity by disrupting cellular morphology in the Enterococcus faecalis MCC 2041 T and Salmonella enterica serovar Typhimurium MTCC 98, at a dose of 375 μg/ml and 750 μg/ml, respectively. The SEM study shows a significant rupturing of E. coli and E. faecalis cells due to TAME induced autolysis. It has synergistic activity with ampicillin. The in silico molecular docking through the AutoDock Vina 4.2 and GROMACS (ver. 5.1) Charmm27 force field results showed that the TAME had a strong binding affinity Escherichia coli DNA Gyrase B (PDB ID: 5l3j.pdb) protein and caused conformational changes. Thus, the manuscript reports the first time on the characterization of TAME from this plant with a detailed antibacterial mode of action studies.

Abstract
Microwave-assisted extraction (MAE) is a sustainable non-contact heating source and has been extensively researched for extraction of plant bioactives. There are various derivatives or modules available for MAE and solvent free microwave extraction (SFME) is one of them where by operational aspects of MAE have been maneuvered to make it compatible for extraction of essential oil (EO). This article makes an attempt to overhaul the science of distillation by revisiting SFME and trying to learn through a comprehensive tutelage comprising of 20 years of published literature in Web of Science so that a shrewd decision can be obtained through a cross talk based critical analysis on the science SFME. A total of 312 articles within the time frame of 2001-2020 were extracted from WOS and critically analyzed. Considering the various uncertainties involved with SFME the articles establishes some global working standards and tries to explore the dynamic relationship between plant part/genus and microwave power, microwave power and time, microwave power and extracted volatile principles, prioritizes plant family selection and also presents a research blueprint of SFME. A techno-commercial feasibility study has been presented for smooth industrial transition of SFME. The tutelage presented decodes the publication trends and SFME blueprint.

Abstract
In this work, we report the redox properties in organic catalytic transformation and antibacterial activity of novel Cu x Ag x Zn1-2x O nanocomposites. Cu- and Ag-doped ZnO [Cu x Ag x Zn1-2x O (x = 0.1)] (CAZ), Cu-doped ZnO [Cu x Zn1-x O (x = 0.1)] (CZ), and Ag-doped ZnO [Ag x Zn1-x O (x = 0.1)] (AZ) were prepared via a chemical co-precipitation method. The synthesized nanocomposites were characterized using different spectroscopic techniques. The catalytic activity of CAZ, CZ, and AZ was examined for the reduction of 4-nitrophenol (4-NP) and 4-nitroaniline (4-NA) in the presence of NaBH4 in an aqueous medium. The photocatalytic oxidation efficiency of these catalysts was also observed against naphthol orange (NO) under ultraviolet light. It was found that the catalytic reduction and oxidation efficiency of CAZ is higher than that of CZ and AZ in 4-NP/4-NA and NO in a water solvent, respectively. The antibacterial property of CAZ was also studied against Gram-positive and Gram-negative bacteria by agar well diffusion and the minimum inhibitory concentration methods. It was found that CAZ shows better antimicrobial activity compared to its parental Cu(NO3)2·3H2O, AgNO3, and ZnO. Therefore, the incorporation of Cu and Ag into ZnO increases its catalytic and antimicrobial activity remarkably. Fourier-transform infrared and X-ray diffraction (XRD) studies of CAZ indicate the incorporation of Cu and Ag into the lattice of ZnO. The phase structure of CAZ was wurtzite hexagonal, and the average crystallite size was 93 ± 1 nm measured from XRD. The average grain size and particle size of CAZ were found to be 200 and 100 ± 5 nm originating from SEM and transmission electron microscopy studies, respectively. The optical energy band gap of CAZ is 3.15 eV, which supports the excellent photocatalyst under UV light. CAZ also exhibits good agreement for photoluminescence properties with a high intensity peak at 571 nm, indicating surface oxygen vacancies and defects which might be responsible for higher photocatalytic activity compared to others. The nanocomposite shows excellent reusability without any significant loss of activity.

Abstract
The fruits and aerial parts of Sechium edule (Jacq.) Sw. (Cucurbitaceae) are a popular cook vegetable being used in different parts of the world with ethnomedicinal and pharmacological values. However, the beneficial health attributes of the tuberous roots have been less exploited. The present study aimed to determine the prebiotic potentiality of the storage carbohydrates from this part. The carbohydrate fractions were harvested by hot-water, cold-water, hot-acid, hot-alkali, and hot 80% ethanol treatments following the standard protocol. The fractions were tested for in vitro prebiotic efficacy, hypocholesterolemic and antioxidant potentials, and in vivo health attributes in Swiss albino mice. The partial characterization was performed by high-performance thin-layer chromatography (HPTLC) and spectroscopic analyses by Fourier-transform infrared spectroscopy (FT-IR) and electrospray ionization mass spectrometry (ESI-MS). The highest prebiotic index was observed in hot-water and ethanol (Et-OH) fractions with the antioxidant IC50 values of 35.46 ± 0.33 and 32.56 ± 0.48 µg/ml, respectively. The HPTLC, FT-IR, and ESI-MS analyses showed that the hot-water and Et-OH carbohydrate fractions are rich in low-degree polymerizing inulin-like fructooligosaccharides (FOS). The fractions had a significant prebiotic index, hypocholesterolemic, and antioxidant activities. The synbiotic combination of the fractions with the probiotic LAB improved gut colonization and gut immune enhancement with significantly lowered triglycerides, serum LDL, and serum VLDL cholesterols. A significantly enhanced HDL cholesterol level proves its health beneficial attributes comparable to the commercial inulin prebiotics. Thus, this plant's novel inulin-like FOS may substitute the high-cost commercial prebiotics for our daily life. PRACTICAL APPLICATIONS: Prebiotics are low-degree polymerizing oligosaccharide food ingredients having multifaceted health benefits. For this reason, there is an ever-increasing global demand for such novel prebiotics. Therefore, finding out some novel prebiotic from conventional food sources may provide an alternative dietary source to fulfill the consumer demand. Sechium edule is a famous cook vegetable used by many ethnic communities across the globe. For the first time, the study revealed novel inulin-like fructooligosaccharides in the tuberous roots having hypocholesterolemic and synbiotic efficacy with GRAS lactic acid bacteria.

Abstract
The review article serves as a mini directory of medicinal plants (662 medicinal plants have been identified) that have been investigated for antiviral property between 2015 and 2019. Data have been extracted from Scopus using specific keywords followed by manual sorting to avoid any duplication. Critical analyses of handpicked data have been presented. Mapping of medicinal plants, followed by critical analysis on the families and plant parts investigated in the said tenure, and its correlation with the participating countries and virus types have been critically analyzed. Interceptive role of phytochemicals in impeding viral replication has also been taken note of. Emphasis on India's exploration of various medicinal plants has also been given. Also presents a tutelage, which is likely to revive the interest in natural products for search of potential antivirals. This review is expected to serve as a rich data bank and as a guiding principle for researchers who are planning to explore medicinal plants in search for potential antiviral. It is time that researchers need to revisit their countries' own history of traditional medicine to predict something worthful in future.

Abstract
The main objective of the study is to characterize two new strains of Aspergillus fumigatus through morphometric, biochemical, molecular methods, and to evaluate their antimicrobial potentiality. The micro-morphotaxonomy, growth, and metabolic behavior of the strains, nHF-01 and PPR-01, were studied in different growth conditions and compared with standard strain. The molecular characterization was done by sequencing the ncrDNA ITS1-5.8S-ITS2 and D1-D2 domains of the nc 28S rDNA region and compared with a secondary structure-based phylogenetic tree. The secretory antimicrobials and pigments were characterized by TLC, UV-Vis, and FT-IR spectroscopy. Both the strains showed distinct growth patterns in different nutritional media and could assimilate a wide range of carbohydrates with distinctive biochemical properties. The molecular characterization revealed the strains, nHF-01 and PPR-01, as Aspergillus fumigatus (GenBank Accession No. MN190286 and MN190284, respectively). It was observed that the strain nHF-01 produces red to brownish pigments having mild antimicrobial activity while the strain PPR-01 does not represent such transformations. The extractable compounds had a significant antimicrobial potentiality against the human pathogenic bacteria. From this analysis, it can be concluded that the nHF-01 and PPR-01 strains are distinct from other A. fumigatus by their unique characters. Large-scale production and detailed molecular elucidation of the antimicrobial compounds may lead to the discovery of new antimicrobial compounds from these strains.

Abstract
Bacteria need to adopt to different behavioral tuning depending on the dynamic eco-physiological conditions they are exposed to. One of these adaptive strategies is the use of motility. Here we report the twitching motility response of four endophytic isolates of Bacillus sp. when exposed to different eco-physiological stimuli like different nutrient sources, and mechanical and chemical antagonists on solid surfaces. These endophytic bacteria were isolated from different parts of a hemiparasite Loranthus sp. Jacq. (Loranthaceae) growing on economically important mango trees. The results show that the twitching motility of these bacteria was more when exposed to organic acids, metals salts (among nutrients) and mechanical shearing (stress) than the other factors. Their motility is not affected by surface lubrication or EPS production, but instead is influenced by shear-sensitive structures and affinity to metal ions. Further molecular studies are needed to elucidate the basis of this twitching behaviour on solid surfaces.

Abstract
Pollution due to release of polycyclic aromatic hydrocarbons from thermal power plants is a major global issue as the same is highly toxic and carcinogenic. The current research aims to investigate the responses of a dietary plant Amaranthus cruentus towards PAH pollution. For the said purpose, the plant was collected from agricultural land in close vicinity to thermal power units and the effects of PAH pollution on its chlorophyll and various nutraceutical content was evaluated. Oxidative stress biomarkers and antioxidant defense enzymes status and PAH accumulation was quantified as well. Real-time evidence of cell death, depletion of nutraceutical resources, and stomata configuration was generated through various histochemical studies and SEM analysis. Results indicated significant decline of chlorophyll a to the extent of 77% when compared to control. Oxidative stress markers, namely, superoxide radical, H2O2, and hydroxyl radical in pollution exposed plants were 12.7, 2.2, and 2.4 times respectively higher over the control which eventually resulted in 35% more cell death for the pollution exposed group. Total phenolics and flavonoids showed a decline of 57.6% and 41.3% respectively in the group exposed to PAH pollution. Similar decreasing trend was also observed for ascorbic acid, α-tocopherol, β-carotene, total proteins, and carbohydrate contents as well. PAH-induced stress also resulted in complete imbalance in the redox homeostasis of the plant which was evident from increase in super oxide dismutase, catalase, and peroxidase antioxidant enzymes by more than 2-fold when compared to control. PAH accumulation in sample group was 10-20 times more when compared to control. Proteomic analysis also indicated upregulation of some proteins related to stress situation. Results are evident of the fact that severe depletion of nutraceutical resources of dietary plants can take place if subjected to oxidative stress arising from PAH pollution.

Abstract
Diospyros melanoxylon Roxb. (D. melanoxylon) belongs to the family Ebenaceae and its leaves are very well known for making beedi throughout the World. The current study estimated the comparative extraction technique and its in-vitro antidiabetic prospective of the leaves of D. melanoxylon. Qualitative phytochemicals analysis of the samples from D. melanoxylon was carried out for the detection of secondary metabolites. Total phenolics, flavonoids, triterpenoids and tannins content of D. melanoxylon were estimated using colorimetric assay. Microwave-assisted extraction (MAE) technique with a low carbon output was observed for the speedy extraction of bioactive compounds obtained from Diospyros melanoxylon leaf extract. MAE produced a maximum yield of bioactive compounds which was found to be more efficient than ultrasound, soxhlet and maceration extraction. Qualitative HPLC analysis was performed for bioactive compounds. The in-vitro antidiabetic assay was performed using α-amylase and α-glucosidase inhibitory activity. In conclusion, the fractions exhibited the concentration-dependent inhibitory effect with significant (P < 0.0001) result. So the above performance might be accountable for the antidiabetic activity of D. Melanoxylon leaf extract due to presence of bioactive compounds.

Abstract
Pediococcus acidilactici LAB 5 produces antifungal compound(s), as well as bacteriocin, which was isolated from vacuum packed fermented meat. This bacterium exhibits varying degrees of antifungal activity against a number of food and feed borne molds and plant pathogenic fungi, such as Alternaria solani, Aspergillus fumigaus, A. parasiticus, Cladosporium herbarum, Colletotrichum acutatum, Curvularia lunata, Fusarium oxysporum, Microsporium sp, Mucor sp, and Penicillium sp. The production of antifungal compound(s) showed a great degree of media specificity and it was strictly restricted to MRS agar media. No production of antifungal compounds was detected in TGE, and TGE+ Tween 80 plates, though the latter supported the highest amount of bacteriocin production at 37°C after 24 hrs. Antifungal compound produced by LAB 5 was extracted using diethyl ether. The minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) of the compound were determined against Curvularia lunata. Chemically the antifungal substance was a phenolic compound with aromatic unsaturation, as evidenced by UV and IR spectroscopy. This is the first report of the production of antifungal compounds by Pediococcus acidilactici LAB 5.

Abstract
The article is basically an attempt to provide a consolidated report on impact assessment and trends in research pertaining to accumulation and curbing the menace of polyaromatic hydrocarbon (PAH) accumulation in leaves. Emphasis is given to understand the consequences of the fact that edible/medicinal plants cultivated in PAH contaminated soil or close to such places which are potential liberators of PAHs can virtually act as transporters for direct PAH entry into biological systems. An attempt has been made to predict the future by digging out golden facts from history. Extensive Scopus-based data mining has been done to dig out research data since last 10 years (2006-2016) pertaining to the said area. Critical analysis of statistical data on research trends highlighting the different aspects of evaluation of PAH accumulation in leaves has been described. The concentrate of all researches for the said period have been presented as few golden principles which shall serve as important facts for researchers and policy makers for curbing the menace of PAH-induced oxidative stress in plants and shall also provide start-up ideas for researchers new to the area. Critical analysis of trends in phytoremediation aspect has also been duly highlighted to measure the intensity of restoration steps taken by researchers and government to safeguard the future generations.

Abstract
Darjeeling and Sikkim Himalayas, a part of Eastern Himalayan Hotspot, is characterized by its richness of plant diversity. Herbal medicine has been one of the most popular and reliable healing practices among the different ethnic groups of this region for ages. However, the lack of documentation practice by the traditional healers has led to obscurity regarding the efficacy of herbal medicine among the present generation, though they have to depend on the same quite often. Meanwhile, several reviews have attempted to document the plants used for the treatment of diabetes from this region, but interestingly, very few research works can be obtained regarding the characterization of antidiabetic properties of the plants of this region. Therefore, it demands a better understanding of the potentiality of these plants in the purview of scientific evidence. This review article reports 55 such plant species which have been reported to be frequently used in the treatment of hyperglycemia and our objective was to validate the potentiality of the plants in the light of recent phytochemical and pharmacological researches being carried out locally or elsewhere.

Abstract
Objectives: The present study investigated the protective effect of Wattakaka (W.) volubilis leaf extract against streptozotocin (STZ)-induced diabetes in rats. Methods: Male Wistar rats were divided into five groups (with six rats in each group) and were fed ad libitum. The rats were fasted for sixteen hours before diabetes was induced by injecting a single dose of 90 mg/kg body weight of STZ in 0.9-percent normal saline through an intraperitoneal route. The five groups were as follows: Group 1: normal control (saline-treated), Group 2: untreated diabetic rats, Groups 3 and 4: diabetic rats treated orally with petroleum ether cold maceration extract (PEME) of W. volubilis(50 and 100 mg/kg body weight), and Group 5: diabetic rats treated orally with metformin (250 mg/kg body weight). All rats received treatment for 21 days. For the STZ-induced diabetic rats, the blood-glucose, α-amylase, total protein and alanine transaminase (ALT) levels were measured on days 7,14 and 21 of the treatment with PEME of W. volubilis and the treatment with metformin. Histopathological changes in the liver were examined with hematoxylin-eosin staining. Morphological changes in the liver were also examined with glutaraldehyde fixation. Results: The treatments with PEME of W. volubilis and with metformin in experimental rats by oral injections for 21 days produced reductions in the levels of serum biochemical markers. Histopathology and scanning electron microscopy results showed that the administrations of PEME of W. volubilis and of metformin suppressed the generation of abnormal liver cells in the STZ-treated rats. Conclusion: These results suggest that both PEME of W. volubilis and metformin have a protective effect against STZ-induced diabetes.

Abstract
Ischemic brain injury is one of the leading causes of death worldwide and has attracted a lot of attention in the field of drug discovery. Cerebral ischemia is a complex pathological process involving a series of mechanisms, including generation of free radicals, oxidative stress, disruption of the membrane function, release of neurotransmitters and apoptosis. Thrombolytic therapy is the most effective therapeutic strategy, but the benefits are far from being absolute. Increased attention in the field of drug discovery has been focused on using natural compounds from traditional medicinal herbs for neuroprotection, which appears to be a promising therapeutic option for cerebral ischemia with minimal systemic adverse effects that could limit their long term use. The scenario calls for extensive investigations which can result in the development of lead molecules for neuroprotection in the future. In this context, the present review focuses on possible mechanisms underlying the beneficial effects of herbal drugs in patients with cerebral ischemic injury. Natural compounds have been demonstrated to have neurofunctional regulatory actions with antioxidative, anti-inflammatory, calcium antagonizing and anti-apoptotic activities. Among the several leads obtained from plant sources as potential neuroprotective agents, resveratrol, EGb761, curcumin and epigallocatechin-3-gallate have shown significant therapeutic benefits in cerebral ischemic conditions. However, ligustilide, tanshinone, scutellarin and shikonin are the few lead molecules which are under investigation for treatment of cerebral ischemia.

Abstract
Ayurveda has been the main guiding force in drug discovery from traditional medicine. In concept, this system is rooted in folk or ethnomedicine and in practice it shows further refinement and development in accordance with local traditions. Isolation of active principles from crude drugs, their pharmacological evaluation, therapeutic proving and clinical application resulted in the genesis of modem or so called allopathic medicine. To keep the opportunity alive for further development in traditional as well as modem medicines, it is necessary to have an uninterrupted connection with ethnomedicine. Since the practice of ethnomedicine is based on the age-long indigenous knowledge which has been orally transmitted through generations and sustained in traditions there is an urgent need to document such knowledge. The ongoing strategies adopted in India to document the precious traditional knowledge and conserve medicinal plants are discussed in this communication. India with her rich plant wealth and traditional knowledge about the medicinal use of plants has tremendous scope to provide leadership in ensuring human health and longevity.

Abstract
INTRODUCTION Extraction forms the very basic step in research on natural products for drug discovery. A poorly optimised and planned extraction methodology can jeopardise the entire mission. OBJECTIVE To provide a vivid picture of different chemometric tools and planning for process optimisation and method development in extraction of botanical material, with emphasis on microwave-assisted extraction (MAE) of botanical material. METHODS A review of studies involving the application of chemometric tools in combination with MAE of botanical materials was undertaken in order to discover what the significant extraction factors were. Optimising a response by fine-tuning those factors, experimental design or statistical design of experiment (DoE), which is a core area of study in chemometrics, was then used for statistical analysis and interpretations. RESULTS In this review a brief explanation of the different aspects and methodologies related to MAE of botanical materials that were subjected to experimental design, along with some general chemometric tools and the steps involved in the practice of MAE, are presented. A detailed study on various factors and responses involved in the optimisation is also presented. CONCLUSION This article will assist in obtaining a better insight into the chemometric strategies of process optimisation and method development, which will in turn improve the decision-making process in selecting influential extraction parameters.

Abstract
BACKGROUND Pediococcus acidilactici LAB 5 produces an antifungal compound under in vitro conditions in an inducer-dependent manner. The main objective of the present study was to partially characterise this antifungal compound by UV-visible, IR, (1)H NMR, (13)C NMR and GC/MS analyses and also to assess its potentiality against a number of food spoilage, plant-pathogenic and human-pathogenic fungal species. RESULTS The strain produced a broad-spectrum antifungal compound(s) that was induced by certain constituent factors of MRS and malt extract media. The production was higher in solid culture than in broth culture. The product was found to be a mixture of lactic acid and a compound of molecular mass 83. The minimum inhibitory concentrations (MIC90, 1.32-2.86 g L(-1)) of the active extract were much lower than those of sodium benzoate and calcium propionate. Scanning electron micrographs proved its drastic action on the development of conidial structures. CONCLUSION The chemical analysis indicated a novel compound with fungicidal activity. This compound could be used in fermented foods and feeds to extend their shelf life and also in agricultural crop plants against certain fungal pathogens.

Abstract
INTRODUCTION Triterpenoids are a group of important phytocomponents from Ficus racemosa (syn. Ficus glomerata Roxb.) that are known to possess diverse pharmacological activities and which have prompted the development of various extraction techniques and strategies for its better utilisation. OBJECTIVE To develop an effective, rapid and ecofriendly microwave-assisted extraction (MAE) strategy to optimise the extraction of a potent bioactive triterpenoid compound, lupeol, from young leaves of Ficus racemosa using response surface methodology (RSM) for industrial scale-up. MATERIAL AND METHOD Initially a Plackett-Burman design matrix was applied to identify the most significant extraction variables amongst microwave power, irradiation time, particle size, solvent:sample ratio loading, varying solvent strength and pre-leaching time on lupeol extraction. Among the six variables tested, microwave power, irradiation time and solvent-sample/loading ratio were found to have a significant effect (P < 0.05) on lupeol extraction and were fitted to a Box-Behnken-design-generated quadratic polynomial equation to predict optimal extraction conditions as well as to locate operability regions with maximum yield. RESULTS The optimal conditions were microwave power of 65.67% of 700 W, extraction time of 4.27 min and solvent-sample ratio loading of 21.33 mL/g. Confirmation trials under the optimal conditions gave an experimental yield (18.52 µg/g of dry leaves) close to the RSM predicted value of 18.71 µg/g. CONCLUSION Under the optimal conditions the mathematical model was found to be well fitted with the experimental data. The MAE was found to be a more rapid, convenient and appropriate extraction method, with a higher yield and lower solvent consumption when compared with conventional extraction techniques.

Abstract
For pharmaceuticals ranging from Digitalis to vincristine, the ethnobotanical approach to drug discovery has proven successful. The value of ethnobotanical information in drug development is based on several factors, which are discussed. Published ethnomedical information has many strengths and weaknesses relative to the ability to establish a corresponding biological effect in the laboratory. The ability to correlate ethnomedical reports with corresponding scientific studies could lead to improved selection of plants for further scientific studies. The application of NAPRALERT database in this regard is also discussed. An elaborate plant to drug pathway has been traced out for young researchers to make the drug discovery pathway more approachable. Various cautions related to possible errors during the ethnobotanical approach have also been highlighted.

Abstract
CONTEXT Liver disease is a serious ailment and the scenario is worsened by the lack of precise therapeutic regimens. Currently available therapies for liver ailments are not apposite and systemic toxicity inhibits their long term use. Medicinal plants have been traditionally used for treating liver diseases since centuries as the toxicity factor appears to be on the lower side. OBJECTIVE Several phytochemials have been identified which have significant hepatoprotective activity with minimal systemic adverse effects which could limit their long term use. The scenario calls for extensive investigations which can lead to development of lead molecules for hepatoprotective molecules of future. This review deals with the biological activity, mode of action and toxicity and forthcoming application of some of these leads. METHODS These generally have strong antioxidative potential and cause induction of antioxidant enzymes like superoxide dismutase, reduced glutathione and catalase. Additional mechanisms of hepatoprotection include stimulation of heme oxygenase-1 activity, inhibition of nitric oxide production, hepatocyte apoptosis and nuclear factor-κB activation. RESULTS AND CONCLUSION Out of the several leads obtained from plant sources as potential hepatoprotective agents, silymarin, andrographolide, neoandrographolide, curcumin, picroside, kutkoside, phyllanthin, hypophyllanthin, and glycyrrhizin have been established as potent hepatoprotective agents. The hepatoprotective potential of several herbal medicines has been clinically evaluated. Significant efficacy has been seen with silymarin, glycyrrhizin and Liv-52 in treatment of hepatitis, alcoholic liver disease and liver cirrhosis.

Abstract
The matured fruits of Diospyros peregrina are successfully employed by the traditional healers and local people of costal West Bengal, India for the treatment of diabetes. Present investigation was undertaken to evaluate the role of hydroalcoholic extract of D. peregrina (HDP) on type 2 diabetes as well as the augmented oxidative stresses associated with it. Oral administration of HDP at 25, 50 and 100 mg kg(-1) body weight per day to diabetic rats was found to possess significant dose-dependent hypoglycemic and hypolipidemic activity. The diabetic rats showed lower activities of superoxide dismutase (SOD), catalase (CAT) and reduced glutathione (GSH) content in hepatic and renal tissues as compared to normal rats. The activities of SOD, CAT and GSH were found to be increased in extract-treated diabetic rats in selected tissues. The increased level of lipid peroxidation (thiobarbituric acid reactive substances) in diabetic rats was also found to be reverted back to near normal status in extract-treated groups. Thus it may be concluded that the HDP may produce its hypoglycemic effect through antioxidant defense mechanism.
