Pharmacognostical and Phytochemical Screening of Leaves of Medicinal Plants

India is solitary of the richest floristic region of the world and has been a resource of plants and their yield since antique and man uses them in different ways according to his requirements, predominantly as food or as medicine. The preliminary Pharmacognostic study on leaves of medicinal plants plays an incredibly significant role in detection of the purity and quality of crude drugs. Medicinal plants which were originated on earth have notorious medicinal consequence and their usage is growing day by day in our daily life. The present efforts embody the investigation conceded out to establish methods for quality control of herb as per WHO guidelines. Entire botanical valuation which comprises macroscopic, microscopic, phytochemical assessment and physicochemical parameters like extractive value, moisture content, dry weight and ash value have been studied. The shade dried powder and various solvent extracts (viz., methanol, ethanol, aqueous, chloroform and acetone) have been analyzed for their phytoconstituents and fluorescence characters. The occurrence of alkaloid, phenol, steroid, flavonoid, saponin, tannin, and some other chemical constituents were recorded. Exploring the natural products has proved to be the most successful strategy for the discovery of new drugs. The present study has made an attempt to get referential information for the correct identification of the crude drug.
