用高压液相色谱法对慢肝宝冲剂中的五味子乙素作了定量分析。样品用正己烷提取，再转移至甲醇中，在ＳＰＨＥＲＩ－５ＲＰ－１８柱上，用７５％甲醇作流动相，各成分能很好分离。以标准曲线法测定了不同批号的６批样品中五味子乙素的含量。
Quantitative analysis of schisandrin B in Ganchangbao granules was performed by high pressure liquid chromatography. The sample was extracted with n-hexane and transferred to methanol. On a SPHERI-5RP-18 column, 75% methanol was used as a mobile phase and the components were well separated. The standard curve method was used to determine the content of schisandrin B in 6 batches of different lots.
