Methods The sample was separated with a C18 column (150mm×4.6mm, 5μm) at 30℃ with the mobile phase of methanol and water (74:26); A fluorescence detector was used (λex=230nm λem=460nm); The floss rate was 1mlmin^(-1) Results The retention time of aesculin was(3.620±0.05)min; A good linear relationship of aesculin in the plasma samples at the concentration between 0.1mgL^(-1) and 100mgL^(-1) was observed (r=0.997); The mean absolute recovery was 74.0%~82.6% and the lowest detective limit was 0.05ng; Both the intra-day and inter-day precisions were less than 9.0%.

以C18柱(150mm×4.6mm，5μm)分离；流动相为甲醇－水(76：24)；流速：1mlmin^(-1)；柱温：30℃；荧光检测器，激发波长230nm，发射波长460nm：结果秦皮甲素的保留时间为(3.620±0.05)min；血药浓度在0.1~100mgL^(-1)范围内线关系良好(r=0.997)；绝对回收率为74.0%-82.6%，日内、日间精密度均＜9.0%，最低检测限为0.05ng。
