Phytochemical Screening and In Vitro Biological Activities of Ethanolic Leaf Extract of Grewia asiatica L.

Abstract :

Plumeria acuminata is a small laticiferous tree, a native of tropical America, which is commonly used in several traditional medicines to cure various diseases. The objective of this study was to develop high performance thin layer chromatography (HPTLC) finger print profile of flavonoid in the flowers of P. acuminata . Preliminary phytochemical results showed the presence of alkaloids, flavonoids, steroids, glycosides, reducing sugar, coumarins and triterpenoids. The results showed the presence of flavonoid, quercetin at 1.7264%w/w. The proposed HPTLC method provides a good resolution of quercetin from other constituents present in the ethanolic extract of dried flowers of P. acuminata. The method is rapid, simple and precise.
