Objective To optimize the extraction technology for phenylethanoid glycosides in Callicarpa kochiana Makino. Methods The content of verbascoside and forsythiaside was determined by high performance liquid chromatography(HPLC). Orthogonal design was used to optimize the extraction technology,and yield rates of total phenylethanoid glycolsides,verbascoside and forsythiaside were adopted as evaluation indexes. Results The optimum technology was circumfluence extracting for three times by 70 % alcohol with solid-liquid ratio at 1∶15,1.5 hours every time. Conclusion The optimum extraction technology is simple and feasible,the results are stable and reliable,and the technology can be used for the extraction of phenylethanoid glycosides in Callicarpa kochiana Makino.
