  • Title: Antioxidant activity of extract of Rhus oxyacantha root cortex.
    Author: Tebourbi O, Trabelsi C, Ben Nasr C, Sakly M.
    Journal: Indian J Exp Biol; 2006 Mar; 44(3):246-9. PubMed ID: 16538865.
    Abstract:
    In the present study, the root extract of Rhus oxyacantha contained 25.33 mg of catechin equivalent per mg of fresh wt and was found rich in proanthocyanidins compared to vine shoot, grape pips and leaves. The chromatographic analysis of the extract suggested the presence of (+) catechin, (-) epicatechin -3-O-gallate as well as proanthocyanidinic oligomers and polymers. Root cortex inhibited the ascorbic acid oxidation by dioxygen. It also prevented DDT-induced thymocytes death in a dose-dependent manner. The results suggested antioxidant property of root extract of Rhus oxyacantha which could be ascribed to its free radical scavenging nature.
