Study on DPPH Radical Scavenging Ability of Raw Betel Nut Extract

Abstract

Abstract: Three extracts of raw betel nut were extracted by chloroform,ethanol and water orderly,and their 1,1-diphenyl-2-picrylhydrazyl(DPPH) radical scavenging abilities were studied in two solvents(ethanol and ethyl acetate) separately. Results showed that the extracts of raw betel nut have the DPPH free radical scavenging abilities in ethanol and ethyl acetate solvent,and the order of the abilities these extracts at the same concentration is:ethanol extract > aqueous extract > chloroforme xtract.

Key words: betel nut extract, free radical, 1,1-diphenyl-2-picrylhydrazyl(DPPH)
