摘　　要：[Objectives]The purpose of this study was to establish a method for the determination of five kinds of flavonoids in trichosanthes peel.[Methods]The contents of rutin,isoquercitrin,quercitrin,quercetin and kaempferol in trichosanthes peel samples collected from different sites were determined by high-performance liquid chromatography.With each component as an index,principal component analysis and cluster analysis were performed.[Results]The contents of flavonoids in the trichosanthes peel samples from different sites were different.The cumulative variance contribution rate of isoquercitrin was 95.514%.The results of cluster analysis show that the quality of trichosanthes peel from Anhui was the best.[Conclusions]Taking isoquercitrin as a common factor to carry out content determination will help to better control the quality of trichosanthes peel.
