摘　　要：通过测定猪油的过氧化值(POV)、总抗氧化能力、羟自由基(.OH)以及超氧阴离子自由基(O2.)的清除能力检测马尾松、黑松和湿地松3种松针水提液和醇提液的抗氧化能力。结果表明:3种松针水提液的总抗氧化能力、抑制猪油的脂质过氧化都具有较好效果(P<0.01),但醇提液效果不及水提液;3种松针的醇提液和水提液(湿地松水提液除外)对.OH的清除效果极显著(P<0.01),对O2.也有很强的清除作用,而且清除能力与质量浓度有一定的关系。结论:3种松针水提液及醇提液均具有一定的抗氧化能力。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（P0.01） 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（P0.01）,but all the six extracts exhibited a strong ability to scavenge superoxide free radicals in a dose-dependent manner.
