Abstract

Antioxidant and free radical scavenging activities of the extracts of sumac (Rhus coriaria) fruits and cassia (Cinnamomum cassia) cortex were studied. Plant samples were extracted with methanol:water (80:20) and an aliquot of each extract was fractionated using n-hexane and ethyl acetate. Antioxidant activities of n-hexane, ethyl acetate and water fractions were measured using Fe+2 induced linoleic acid-TBA-peroxidation reaction and the Rancimat methods. Free radical scavenging activities of the fractions were determined on 2,2-diphenyl-1-picrylhydrazyl radical (DPPH). Results were compared with those for butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT). The ethyl acetate fraction of plant materials exhibited a marked antiradical activity on DPPH.
