PHARMACOGNOSTIC AND PRELIMINARY PHYTOCHEMICAL SCREENING OF LEAVES OF CYNODON DACTYLON PERSOONAbstract
Many plants used as traditional medicine. Pharmacognostic studies of crude drug play a very important role in the identification of the purity and quality of crude drugs. The present study deals with the pharmacognostic, preliminary phytochemical investigation of Cynodon dactylon Persoon belonging to family Poaceae. In this, pharmacognostic studies are concerned for the determination of physicochemical parameters like ash values, extractive values, and loss on drying fluorescence analysis also the macroscopic and microscopic evaluation carried out. .The leaves were subjected to successive soxhlation using petroleum ether, ethyl acetate, alcohol, and water. The extracts thus obtained were studied for preliminary phytochemical investigation for detection of the presence of various chemical constituents like alkaloids, glycosides, steroids, tannins, saponins, fats and oils, flavonoids, etc.
