摘　　要：目的:探讨肖氏生物液抗氧化活性。方法:用石油醚、氯仿、乙酸乙酯依次对肖氏生物液进行分段萃取,采用DPPH法测定各种提取物对DPPH.的清除作用。结果:肖氏生物液石油醚提取物、氯仿提取物、乙酸乙酯提取物、水提取物对DPPH.清除作用的IC50值分别为11.713 g/L、10.534 g/L、6.660 g/L及11.177 g/L。结论:肖氏生物液不同部位提取物均有抗氧化活性,但主要集中在乙酸乙酯部位上。Objective：To study the antioxidant activity of components in Xiao Bio-liquid.Methods：Four different parts of Xiao Bio-liquid were extracted with petroleum,chloroform,ethyl acetate and water respectively,and the scavenging capacity of them were measured and compared with DPPH assay.Results：Petroleum,chloroform,ethyl acetate and water extracts had scavenging capacity to DPPH· with IC50s of 11.713 g/L,10.534 g/L,6.660 g/L,and 11.177 g/L respectively.Conclusion：All the extracts from Xiao Bio-liquid have antioxidant activity with ethyl acetate component as the major part.
