PHARMACOGNOSTIC AND PRELIMINARY PHYTOCHEMICAL SCREENING OF LEAVES OF RAPHANUS SATIVUS, LINN.Abstract
Raphanus sativus commonly known as radish is cultivated as a crop and having various medicinal uses. It is cultivated all over the world as an edible root vegetable. The present study deals with the pharmacognostic, preliminary phytochemical investigation of Raphanus sativus, Linn. belonging to family Cruciferae. 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.
