The aim of this study was to determine the contents of quercetin and kaempferol in Oxytropis myriophylla in different regions,harvest times and parts of Inner Mongolia.High performance liquid chromatography(HPLC)was used as the research method,and its scientific nature was evaluated.The results showed that the contents of quercetin and kaempferol in Tropisms vulgaris from different regions of Inner Mongolia ranged from 0.19 mg/g to 0.65 mg/g and from 0.04 mg/g to 0.14 mg/g.In different harvest periods,the content of kaempferol in flowering stage was higher than that in fruit stage,while the content of quercetin in fruit stage was higher than that in flowering stage.The contents of two components in different parts of leaves were the highest.The method for the determination of quercetin and kaempferol established in this study has the advantages of simple operation,high accuracy,good repeatability and stability,and is suitable for the determination of quercetin and kaempferol in Oxytropis myriophylla.
