Abstract: The antioxidant activities of aqueous and ethanol extracts from three species pine needles (Pinus massoniana Lamb., Pinus thunbergii Parl. and Piuns elliottii Engelm.) were studied in terms of their total antioxidant capacity (TAC), protective effect against oxidation in lard (expressed as peroxide value) and abilities to scavenge hydroxyl and superoxide anion free radicals. Water extracts from three species pine needles were found to have excellent TAC and anti-lard lipid peroxidation activities (P<0.01) and to be better than ethanol extracts. Except the aqueous extract from Pinus elliottii Engelm. needles, other five extracts had a significant scavenging effect against hydroxyl free radicals (P<0.01), but all the six extracts exhibited a strong ability to scavenge superoxide free radicals in a dose-dependent manner. 

Key words: pine needles, extracts, antioxidation
