Physicochemical and phytochemical studies on leaves of Couroupita guianensis Aubl

Abstract

The present study comprises physicochemical and phytochemical analysis of leaves of Couroupita guianensis Aubl by using standard protocols. The Pharmacognostic study of plant material is an important tool for detecting any adulterations present in it. In the present study, physicochemical parameters such as ash values, foreign matter, loss on drying, moisture content, fluorescence analysis and extractive values in four different solvents (methanol, ethanol, ethyl acetate and petroleum ether) were analysed. Fluorescence analysis of leaf powder showed the presence of different fluorescence with different reagent treatments. The qualitative phytochemical screening was carried out in four different extracts. The results revealed the presence of secondary metabolites such as alkaloids, flavonoids, steroids, carbohydrates, tannins and proteins.
