PHARMACOGNOSTIC STUDIES ON DIOSPYROS MELANOXYLON
AbstractDiospyros melanoxylon is a medium-sized tree or shrub which belongs to the family Ebenaceae. The whole plant is medicinally important and cures several diseases. Therefore, in this context the detailed pharmacognostic study of various parts like leaf, stem, petiole and root has been carried out with the aim to establish its Pharmacognostical standards. The parameters selected were microscopical studies, proximate analysis, fluorescence analysis and preliminary phytochemical screening. The microscopical studies of leaf,stem and root revealed the presence of branched trichomes,spiral xylem vessel. In physicochemical evaluation the ash values and extractive values were studied. Fluorescence analysis performed showed the wide range of fluorescence colors for the crude powder. The Diospyros melanoxylon powder was successively extracted with hexane, benzene, chloroform, ethylacetate, ethanol and water for the identification of the best solvent. Preliminary phytochemical screening was carried out for all the extracts and maximum chemical constituents were observed in the ethanolic extract.
