目的通过对罗汉果干果不同溶剂提取成分抗氧化活性的研究，为深入开发罗汉果药食两用价值提供实验依据。方法用60％乙醇回流提取罗汉果果实成分，并用石油醚、乙酸乙酯、正丁醇依次萃取，研究各种提取物清除DPPH·、ABTS·自由基活性，并以抗坏血酸作为阳性对照。结果罗汉果果实乙酸乙酯、正丁醇提取物（IC50分别为0．42±0．01，1．13±0．03）较抗坏血酸均有较强清除自由基活性作用（P＜0．05）。结论罗汉果果实的提取物有较强的抗氧化活性。

Objective To investigate the antioxidant activity of The fruits of Momordica grosvenori Swin-gle was extracted by 60%ethanol ,and then partitioned respectively by petroleum ether ,ethyl acetate and butyl alcohol .Methods The antioxidant activity of each fraction was assessed by measuring the capability for scaven-ging free radicals such as DPPH · and ABTS· with,ascorbic acid as a positive control .Results The ethyl ac-etate fraction,n-butyl alcohol(IC50 =0.42 ±0.01,1.13 ±0.03)showed higher antioxidant activity than positive control(P<0.05)and its IC50 was (0.42 ±00.1 ) and (1.13 ±0.03),respectively.Conclusion The extracts of Momordica grosvenori Swingle fruits have potent antioxidant activities .
