Abstract

In this present work the fresh flowers of Allamanda Cathartica Linn. were collected and the solution of Allamanda Cathartica was extracted with 90% methanol under reflux.  The alcoholic extract was concentrated in vacuo and the aqueous concentrate, successively fractionated with benzene, peroxide free diethylether and ethylacetate.  The benzene fraction was not yielding any isolable material. The diethyl ether fraction yielded quercetin and ethylacetate fraction yielded quercetin 3-O-rhamnoside (quercitrin). The structure of the isolated compounds was characterized by UV, 1H-NMR and 13C-NMR spectra and identified by paper chromatography (PC).
