采用高效液相色谱法测定秦皮浓缩颗粒中秦皮甲素的含量。色谱柱：Ｓｈｉｍ－ｐａｃｋ ＣＬＣ－ＯＤＳ－Ｃ１８柱）；检测波长：２５４ｎｍ；流动相：甲醇－水－冰醋酸（３１：６９：０．５）；流速：１．８ｍＬ／ｍｉｎ；柱温：４０℃；线性关系在０．９２～４．６０μｇ范围内，ｒ＝０．９９９６，平均加样回收率为９８．４２％，ＲＳＤ为１．７０％。
The content of aesculin in Qinpi Concentrate was determined by HPLC. Column: Shim-pack CLC-ODS-C18 column) Detection wavelength: 254 nm Mobile phase: methanol-water-glacial acetic acid (31:69:0.5); Flow rate: 1.8 mL/min; Column temperature: 40 The linear relationship was in the range of 0.92 to 4.60 μg, r=0.9996. The average recovery was 98.42%, and the RSD was 1.70%.
