以红熟番茄为提取原料，利用超声波技术、常规溶剂技术和超临界CO2技术提取其中的番茄红素并研究了不同提取方式番茄红素的抗氧化活性，通过测定番茄红素的体外DPP H 自由基、羟基自由基和超氧阴离子自由基的清除能力，考察了三种提取方式的番茄红素抗氧化活性并进行了比较。结果表明：三种提取方式的番茄红素对DPP H 自由基、羟基自由基和超氧阴离子自由基均具有较强的清除作用，其中，超声辅助提取番茄红素的清除能力均强于其余两种提取方式的清除能力。抗氧化活性从强到弱依次为超声提取＞常规提取＞超临界CO2提取。

The red and ripe tomatoes are used as extraction materials and the lycopene is extracted by ultrasound-assisted technology,conventional solvent technology,and supercritical CO2 technology. Meanwhile,the antioxidant activity of lycopene extracted by various extraction methods is studied. DPPH radical,hydroxyl radical,and superoxide anion radical scavenging activities are applied to investigate the antioxidant activity of lycopene by various extraction technologies.The results show that three kinds of extraction technologies possess a strong scavenging activity on the above-mentioned three free radicals and the antioxidant activity of lycopene extracted by ultrasound-assisted extraction is stronger than that of the other two extraction methods.The antioxidant activity in turn decreases on ultrasound-assisted extraction,conventional solvent extraction,and supercritical CO2 extraction.
