摘要(Abstract):

[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.
