PHARMACOGNOSTICAL EVALUATION AND PRELIMINARY PHYTOCHEMICAL ANALYSIS OF DIFFERENT PARTS OF LAGERSTROEMIA SPECIOSAAbstract
The present study aimed to determine the pharmacognostical evaluation and phytochemical analysis of the plant part of Lagersreomia speciosa. In this study, a macroscopical, microscopical evaluation was done. Various quantitative parameters such as total ash, acid insoluble ash, water-soluble ash sulphated ash, extractive value with various solvent were done. In the preliminary phytochemical analysis, various chemical test were performed for the determination of phytoconstituents present in the plant. Fluorescence analysis of powder drugs was done in a deferent wavelengthrange. TLC was performing for the methanolic extract taking the solvent system with various ratios. From the experiment result it was found leaves are bitter in taste, the shape is elliptical to oblong, acute base subacute apex, entire margin and pinnate venation the leaves are dorsiventral, long epidermis layer, spongy mesophyll, loosely packed parenchyma cell present in the leaf. Microscopic powder drug analysis shows the prism and rosette shape calcium oxalate crystals, lignified and annular xylem vessels, and multicellular trichomes. From quantitative microscopic study stomatal number, vain-islet number, vein termination number was found 19.4, 9, and 10.4. In the fluorescence analysis, when powder drugs were treated with a different chemical reagent, exhibit different color in various UV light range. Phytochemical analysis revealed the presence of alkaloid, glycoside, carbohydrate flavonoids, and tannin saponin. TLC study of the various solvent extract was done in the different solvent; better resolutions were found in the methanol chloroform system. This study helps to standardization and evaluation of the various part of the Lagerstroemia speciosa.
