摘要

目的:采用二苯基苦基苯肼（DPPH）法研究罗汉果植株茎、叶和果实的抗氧化活性。方法:采用超声提取法分别对罗汉果植株茎、叶和果实进行乙醇提取;采用分光光度法测定各提取物对DPPH的清除能力。结果:罗汉果植株茎、叶、果实对DPPH的半清除率（IC50值）分别为0.756

0.119

0.358 g.L-1。结论:罗汉果植株3个器官均有抗氧化活性。其中

叶的抗氧化能力最强。

Abstract

Objective:The antioxidant activity of siraitia grosvenorii leaves

stems and fruits was studied by 2

2-diphenyl-l-picrylhydrazyl（DPPH） method.Method: The stems

leaves and fruits of siraitia grosvenorii were extracted with ethanol by ultrasonic extraction

and the DPPH clearing rate of different extracts was determined by spectrophotometry.Result:Half clearance of scavenging effect on radical DPPH by three parts including stem

leaf and fruit from Siraitia grosvenorii

i.e.IC50

was 0.756

0.119

0.358 g.L-1 respectively.Conclusion: Extracts from three parts of Siraitia grosvenorii have antioxidant activity.The leaf owns the strongest antioxidant capacity.
