采用高效液相色谱法测定萎胃安冲剂中芍药甙含量。本法以水和甲醇提取，甲醇－水（２１：７９）作为流动相。检测波长为２３０ｎｍ，回收率为９９．０２％，相对标准误差（ＲＳＤ）为１．６９％。
Determination of paeoniflorin in WeiWeiAn Granules by high performance liquid chromatography. This method is extracted with water and methanol, methanol-water (21:79) as the mobile phase. The detection wavelength was 230 nm, the recovery was 99.02%, and the relative standard deviation (RSD) was 1.69%.
