Objective: To study the effects of the free radical scavenging activity of these formulae for blood-activating and stasis-removing such as Xuefu Zhuyu Decoction(XF)
Shaofu Zhuyu Decoction(SF)
Gexia Zhuyu Decoction(GX)
Shentong Zhuyu Decoction(ST)and Tongqiao Huoxue Decoction(TQ). Method: Free radical scavenging activity was determined by 2
2-diphenyl-1-picrylhydrazyl(DPPH)method. Result: The result showed that all these formulae had significant effects on scavenging DPPH radical(P<0.01)
in a dose-dependent manner.. The free radical scavenging capacity on DPPH were in the following descending order:GX>TQ>SF>ST>XF. The scavenging ability in total formula was better than in ethanol precipitant and supernatant. Conclusion: Validation studies proved that the enzyme-linked immunosorbent assay for DPPH had good reproducibility and feasibility. The method could be used as high throughput screening for Chinese herbs and traditional chinese medicine formulae.
