title: Comparison of antioxidant activity in enzyme-independent system of six Stachys species.
abstract: The antioxidant activity of six Stachys species native to Hungary in an enzyme-independent lipid-peroxidation system was examined. The methanolic extracts were found to be more effective than the controls alpha-tocopherol succinate and ascorbic acid. The following components were determined by spectrophotometric analysis: hydroxycinnamic acid derivatives, phenols content and flavonoids.
