Aim: The aim of this study is identification and comparative analysis of bioactive phytochemicals present in methanol and ethyl acetate extracts of different plant organs and callus of Leptadenia reticulata by GC{\textendash}MS technique. Methodology: The shade dried plant samples (leaves stem and root) and callus produced from leaf of L. reticulata were powdered and then sequentially extracted in methanol and ethyl acetate solvents. Total eight extracts were prepared which were Methanolic Leaf Extract (MLE), Methanolic Stem Extract (MSE), Methanolic Root Extract (MRE), Methanolic Callus Extract (MCE), Ethyl Acetate Leaf Extract (EALE), Ethyl Acetate Root Extract (EARE), Ethyl Acetate Stem Extract (EASE) and Ethyl Acetate Callus Extract (EACE). Then, each of the extracts was further subjected to Gas Chromatography{\textendash} Mass Spectrometry (GC{\textendash}MS) analysis. Results: The GC{\textendash}MS analysis of the eight extracts revealed the presence of 77 different types of high and low molecular weight phytochemicals and bioactive compounds in varying quantities. Some of the phytochemicals detected for first time in L. reticulata are γ-sitosterol, Campesterol, Pristane, Hexahydrofarnesol, Stearic acid, Arachidic acid, Coniferyl alcohol, n-Tetracosanol-1, Ascorbic acid 2,6-dihexadecanoate, (2S,3S)-3,7,4{\textquoteright}-Trihydroxy-5-methoxy-6-methylflavanone etc. These chemical compounds are considered biologically active and pharmacologically important. Conclusion: This study gives a detailed comparison of detection and identification of various bioactive phytochemicals from different plant parts (leaves, stem and root) and callus of L. reticulata. This provides a basis for the biological and biochemical characterization of some newly detected biologically and pharmacologically important phytochemical components from this plant.

Background: The focus on herbal plants as medicine is increasing rapidly because of their efficacy and less side effects. The medicinal plants are great alternative as they are renewable and non exhaustive resources. In India these medicinal plants have been part of the people{\textquoteright}s life dating back from centuries. Objectives: The present study is aimed to evaluate anatomical characterization of stem and root of Indigofera tirunelvelica Sanjappa for the first time which can be used in the identification and standardisation of Indigofera tirunelvelica Sanjappa. Results: The stem and root of the plant were evaluated for their microscopic features. In that histochemical localisation of secondary metabolites and transverse section of stem and root were studied. The histochemical localisation result reveals the presence of terpenoids, alkaloids, flavonoids and lignin were found in epidermal, cortical and xylem regions of the stem. Alkaloids, Terpenoids, phenols and lignin were found in the different areas of root. Conclusion: The present study thus emphasis the potentiality of the plant as a drug.

Purpose: To undertake the pharmacognostic studies of Anthocephalus cadamba (Roxb.) Miq. Root for the purpose of identification and differentiation from related species. Methods: The macroscopic and microscopic features of the root were studied, including the use of powder microscopy with the aid of suitable tools and reagents. Physicochemical parameters such as ash value, extractive value and weight loss on drying were also determined. The root powder was successively extracted with different solvents followed by preliminary phytochemical screening of the extracts. Results: Macro- and micro-scopic studies revealed cork i.e. the layer of periderm present above the cortex along with lenticels. The periderm is many layered membranous with irregularly fissured crevices containing phellum and phellogen. Secondary phloem is comparatively massive without lignified tissues i.e. bast fibres and contains sieve tubes, phloem parenchyma, many enriched with starch grains. The secondary xylem lignified mingled with medullary rays, vessels, parenchyma and wood fibers. Preliminary phytochemical screening of different extracts revealed the presence of alkaloids, carbohydrate, protein, gum, steroid, tri-terpenoid, saponin, flavonoid and tannin in the root. Conclusion: The findings of this study facilitate pharmacognostic standardization of the plant material and add clues in the preparation of herbal monographs for Phyto pharmacopeia.
