A SIMPLE TLC METHOD FOR IDENTIFICATION OF QUERCETIN AND ANTIOXIDANT PROPERTIES OF METHANOLIC EXTRACTS OF CISSUS QUADRANGULARIS, CASSIA FISTULA AND CALOTROPIS PROCERA

摘要

The aim of the current study was to screen out the presence of Quercetin and Antioxidant activity in methanolic extract of Cissus quadrangularis, Cassia fistula and Calotropis procera by utilizing their plant parts using TLC. Prescencc of Quercetin was marked by the yellow fluorescent spots when observed under U.V and in the form of grey coloured spot by spraying FeCl, while antioxidant activity was marked by the spray of 0.2% DPPH (2,2-diphenyl-1-picrylhydrazyl) solution. In case of Quercetin the Rfvalues for the different samples were also determined. The present study experimentally proved that the traditional use of Cissus quadrangularis, Cassia fistula and Calotropis procera for the treatment of various diseases may also lead to the development of dmgs having both chemotherapeutic and chemopreventive properties in future.
