摘　　要：　用不同浓度的甲醇和乙醇做溶剂,提取桔皮中的黄酮化合物,对黄酮化合物清除自由基的效果做了研究。结果表明,80%甲醇和70%乙醇提取的黄酮化合物清除自由基的效果最好。它们的自由基清除率分别是36.50%和36.40%。Flavonoid from orange peel were extracted with methanol and alcohol of differentConcentration. Effect of scavenging free radical were studied by flavonoid compounds. The result showed that effect of scavenging free radical of flavonoid compounds extracted by using 80%methanol and 70% alcohol is the best.. Their scavenging free radical rate is 36.50% and 36.40% respectively.
