PHARMACOGNOSTIC AND PHYTOCHEMICAL EVALUATION OF CARYOTA URENS LEAF

Abstract

Caryota urens (Palmae) is native to India. This tree species has been of interest to researchers because it is a medicinal plant employed in the Indian indigenous system of medicine. Pharmacognostic standardization, physic-chemical evaluation of the leafs of Caryota urens was carried out to determine its macro-and micro-scopical characters and also some insoluble ash and sulphated ash values, alcohol- and water-soluble extractive values were determined for phytochemical evaluations. Preliminary phytochemical screening was also done to detect different phytoconstituents. Microscopically, Leaf showed Lamina, midrib regions, stomata. Powder microscopy showed mesophyll region, pitted xylem vessels and paracytic stomata. TLC of petroleum ether and ethanol extract showed three spots using Hexane: Ethyl acetate (12:4) and three spot using Choloroform: Ethyl acetate (5:4). Phytochemically leaves exhibited phytosterols, Flavanoids, Tannin carbohydrates and phenolic compounds.
