辣椒叶醇提物的体外抗氧化活性

摘要

Antioxidant effects were investigated from leaves of chili pepper. Ethanol extracts was extracted from leaves of chili pepper with ethanol in order to measure the content of total flavonoids and analyze the total antioxidant activity, superoxide anion, hydroxyl and DPPH free radical scavenging activity. It was found that total flavonoids was 4.2%in the leaves of chili pepper and ethanol extracts exhibited strong antioxidant activity power and scavenging effect against free radicals. Pepper leaves contain flavonoids , and antioxidant components, had antioxidant effects.%　　探讨辣椒叶抗氧化作用，采用乙醇提取辣椒叶醇提物，测定其总黄酮含量，并考察该提取物体外总抗氧化活性以及清除超氧阴离子自由基、羟自由基和DPPH自由基的能力。结果表明辣椒叶总黄酮含量为4.2%，醇提取物具有较强的体外抗氧化活性和清除自由基的活性。辣椒叶中含有黄酮以及抗氧化活性成分，具有明显抗氧化作用。
