研究提取方法对石榴籽提取物抗氧化活性的影响。以无水乙醇为溶剂，分别采用超声法、回流法、加压法、超声辅助回流法、超声辅助加压法以及超临界法提取石榴籽中抗氧化活性成分，并对其清除 DPPH 自由基的能力、清除羟基自由基的能力、还原能力、脂质过氧化的抑制能力进行检测。结果表明，超声辅助回流法和超声辅助加压法所得石榴籽提取物的抗氧化能力相对于其它方法均有明显提高，尤其对 DPPH 自由基的清除率分别高达92．1％和80.2％。超声辅助能显著提高石榴籽提取物的抗氧化活性。

The effect of extraction methods on antioxidant capacity of extracts from pomegranate seed was studied.With anhydrous ethanol as solvent,ultrasonic method,reflux method,pressure method,ultrasonic-assis-ted reflux method,ultrasonic-assisted pressure method and supercritical method were used to extract antioxidant activity components from pomegranate seeds.The DPPH free radical scavenging activity,hydroxyl free radical scavenging activity,reducing power and lipid peroxidation inhibition ability of extracts were tested.The results showed that,the pomegranate seed extracts extracted by ultrasonic-assisted reflux method and ultrasonic-assis-ted pressure method had better antioxidant capacity compared to other methods,especially the DPPH free radi-cal scavenging rate of pomegranate seed extracts was 92.1% and 80.2%,respectively.Therefore,the ultra-sound-assisted method could significantly improve the antioxidant capacity of pomegranate seed extracts.
