摘要
笔者分析了香白杏果实中总酚、黄烷醇、类黄酮及缩合单宁的含量,研究了香白杏提取物的抗氧化活性以及对羟自由基(·OH)、超氧阴离子(O·2)、脂质自由基(R·)的清除作用。结果表明香白杏中类黄酮、黄烷醇的含量近乎相等,两者远大于缩合单宁的含量。香白杏提取物具有很强的抗氧化活性,对·OH和O·2有较明显的清除效果,但它对R·的清除效果较差。
The contents of total phenolics, flavanol, flavonid and condensed tannin in Xiangbai apricot fruit were analysed.Antioxidant activity and the effects on scavenging hydroxyl radical(·OH), the oxygen free radical(O~·_2), and lipid radical(R~·)in apricot fruit extracts. The results showed that contents of flavanol and flavonoid were almost vesame.Condensed tannin were investigated contents were much less than flavanol and flavonoid in apricot fruit,and the extracts had powerful antioxidant activity and significantly scavenging effects on·OH and O~·_2.but the scavenging effect on R~· was not signicant.
