目的：优化五味子抗氧化物的提取条件；分析湖北产和辽宁产五味子提取物的 DPPH清除能力。方法以 DPPH自由基的清除能力为参考指标，采用单因素实验的方法，考察溶剂种类、乙醇浓度、料液比、提取时间、提取次数和提取方法等因素对五味子提取物抗氧化作用的影响。结果五味子抗氧化物的最优提取条件为：以60％的乙醇为提取溶剂，超声法提取，料液比为1∶30（ g? mL －1），提取次数3次，每次提取20min，室温提取；湖北产和辽宁产五味子提取物清除DPPH自由基的IC50分别为3．79mg? mL －1和7．60mg? mL －1。结论五味子提取物具有较强的抗氧化作用，且湖北产五味子提取物的抗氧化作用比辽宁产五味子...

ABSTRACT:OBJECTIVE To optimize the extraction conditions of Schisandra antioxidant and to analyze the DP-PH scavenging ability of Hubei and Liaoning production of Schisandra chinensis extracts .METHODS Based on DPPH free radical scavenging activity of extracts of Schisandra chinensis and using single factor experiment ,extrac-ting conditions were optimized through a series of comparative researches on the influences of solvent types ,ethanol concentration ,solid-liquid ratio ,extraction method ,extraction time and extraction frequencies .RESULTS The opti-mal conditions for extracting Schisandr...
