摘要:目的建立愈伤灵胶囊中人参皂苷Rg1和Rb1的含量测定方法。方法采用HPLC-ELSD法,色谱柱为Hypersil ODS2(4.6 mm×250 mm,5 μm);流动相为乙腈-水梯度洗脱;蒸发光散射(ELSD)参数:漂移管温度为110 ℃,气体流量为3.02~3.05 SLPM。结果人参皂苷Rg1在2.272~11.360 μg范围内线性关系良好,r = 0.999 1;人参皂苷Rb1在2.232~11.160 μg范围内线性关系良好,r = 0.999 4;两者的平均回收率分别为96.6 %,98.6 %;RSD分别为1.7 %,2.3%。结论该法简便、准确、可靠,可用于愈伤灵胶囊的质量控制。关键词:HPLC-ELSD法; 愈伤灵胶囊; 三七; 人参皂苷Rg1; 人参皂苷Rb1

Abstract:ObjectiveTo establish an HPLC-ELSD method for determination of ginsenoside Rg1 and Rb1 in Yushangling capsule. MethodsThe separation was performed in a Hypersil ODS2 column with a mobile phase of acetonitrile-water in gradient elution, ELSD nebulization at 110 ℃ and flow rate of nitrogen at 3.02~3.05 SLPM. ResultsThe linear range of ginsenoside Rg1 was 2.272~11.360 μg, r = 0.999 1. The linear range of ginsenoside Rb1 was 2.232~11.160 μg, r = 0.999 4. The average recoveries of ginsenoside Rg1 and Rb1 were 96.6 %, 98.6 % respectively, and RSD were 1.7 %, 2.3%. ConclusionThis method is simple, accurate and reliable. It can be used for quality control of Yushangling capsule. ......
