2、照品，采用反相hplc法。结果 不同月份五味子藤茎中三种木脂素成分的含量各不相同五味子醇甲含量在12月份最高为3mgg，4月份最低为4 mgg；五味子甲素在11月份含量最高为.8mgg，3月份最低为.4mgg；五味子乙素在1月份含量最高为mgg，4月份最低为1mgg。结论 不同月份的五味子藤茎均含有木脂素成分，具有较高的开发利用价值，并且以冬季采收为佳。关键词五味子藤茎；木脂素；季节；含量; hplcstudy on the changes of lignans content in stem of schisandra chinensismajor of traditional chines
