摘要：
Bioassay-guided fractionation of the methanol extract from the root of Sophora flaivscens led to the isolation of eight known prenylated flavonoids responsible for the vasorelaxation activity in porcine coronary arteries. Among them, kushenol N and 5-methylsophoraflavanone B strongly induced the relaxation of porcine coronary arteries with respective ED50 values of 8.6 and 12.4 mu m. This activity and the results of a high-performance liquid chromatographic analysis suggest that kushenol N and 5-methylsophoraflavanone B could be active markers in the S. flavescens extract for vasorelaxation activity.
