L. and have been used for hundreds of years to treat hypertension in China. In previous research, there was not a suitable quality control of method for the formulas of L. and It is urgent and essential to develop modern analytical methods for L. and to ensure the quality of the formulas. A rapid approach for simultaneous determination of hyperoside, isoquercitrin and eleutheroside E in L. and by high-performance liquid chromatography with a diode array detector was described and validated. The full method validation, including the linearity, limits of detection and quantification, precision, repeatability, stability and recovery, was examined. All target components, including isomers of hyperoside and isoquercitrin, were baseline separated in 35 min. The developed method was sensitive, reliable and feasible. With this method, the optimal decoction conditions of L. and were selected, and their quality analysis was carried out. Furthermore, an herbal compatibility study of L. and based on detecting variations in the content of their active ingredients was performed by the developed HPLC method. It could be an alternative for the quantitative analysis of herbs that contain hyperoside, isoquercitrin or (and) eleutheroside E in the future.
