EVALUATION OF IN VITRO ANTIOXIDANT PROPERTIES OF GARCINIA BRASILIENSIS LEAF EXTRACTAbstract
The in vitro antioxidant activity of n-hexane, chloroform, ethyl acetate and alcoholic fraction of the total ethanolic extract of the leaves of Garcinia brasiliensis have been tested using various antioxidant model systems viz., ferric reducing power assay and hydrogen peroxide scavenging assay. Ethyl acetate fraction is found to possess higher ferric reducing power and superoxide radical scavenging activity. The estimation of total phenolic and flavonoid contents of the various fractions are studied and the ethyl acetate fraction is found to possess high total phenolic and flavonoid content, thus correlating it with the antioxidant potential of the ethyl acetate fraction.
