摘 要:目的:测定冠心丹参胶囊中丹参素、丹酚酸B、隐丹参酮、丹参酮Ⅰ、丹参酮ⅡA以及人参皂苷Rg1和人参皂苷Rb1的含量。方法:采用高效液相色谱法,以C18柱为色谱柱;流动相为乙腈-0.1%磷酸,梯度洗脱;流速为0.8 mL·min-1;检测波长为270、203 nm。结果:丹参素钠和丹酚酸B、隐丹参酮、丹参酮Ⅰ、丹参酮ⅡA以及人参皂苷Rg1和人参皂苷Rb1分别在7.1~113.6、11.7~187.2、6.6~105.0、6.9~110.2、7.3~116.0、31.2~499.4、27.1~433.7 μg·mL-1呈良好线性关系,平均加样回收率分别是99.51%(RSD=0.91%)、97.73%(RSD=1.35%)、97.20%(RSD=0.78%)、98.47%(RSD=0.69%)、99.12%(RSD=0.31%)、96.64%(RSD=0.86 %)和97.98%(RSD=1.02%)。结论:本方法简便、准确、重复性好,可作为冠心丹参胶囊中主成分的含量测定方法。Objective:To determine the content of the tanshinol natrium,salvianolic acid B,cryptotanshinone,tanshinoneⅠ,tanshinoneⅡA,ginsenoside Rg1 and ginsenoside Rb1 in Guanxin Danshen Capsules.Methods:HPLC was performed on C18 column using acetonitrile-0.1% phosphoric acid (gradient elution) as the mobile phase at a flow rate of 0.8 mL·min-1.The detection wavelengths were set at 270 nm and 203 nm.The column temperature was 30 ℃.Results:Tanshinol natrium,salvianolic acid B,cryptotanshinone,tanshinoneⅠ,tanshinoneⅡA,ginsenoside Rg1 and ginsenoside Rb1 showed good linearity in the concentration range of 7.1-113.6,11.7-187.2,6.6-105.0,6.9-110.2,7.3-116.0,31.2-499.4 and 27.1-433.7 μg·mL-1,respectively.And their average recovery rates were 99.51% (RSD=0.91%),97.73% (RSD=1.35%),97.20% (RSD=0.78%),98.47% (RSD=0.69%),99.12% (RSD=0.31%),96.64% (RSD=0.86%) and 97.98% (RSD=1.02%),respectively.Conclusion:The method is simple and accurate with good reproducibility.It can be used for the determination of the main components in Guanxin Danshen Capsules.
