Antioxidative and free radical scavenging activities of selected medicinal herbs.
The antioxidative and superoxide- and hydroxyl radical-scavenging activities and pro-oxidant effect of twelve selected medicinal herbs were studied. The aqueous extracts of Coptis chinensis, Paeonia suffruticosa, Prunella vulgaris and Senecio scandens exhibited the highest potency in inhibiting rat erythrocyte hemolysis and lipid peroxidation in rat kidney and brain homogenates. The aforementioned four herbs also demonstrated strong superoxide- and hydroxyl radical-scavenging activity, but exerted only a slight pro-oxidant effect.
