摘 要:目的:建立测定益心舒胶囊中丹参素、原儿茶醛、阿魏酸、丹酚酸B含量的方法。方法:采用双波长高效液相色谱法。色谱柱为Eclipse XDB-C18,流动相为0.5%磷酸水溶液-甲醇-乙腈(梯度洗脱),流速为1.0 ml/min,检测波长为280 nm(丹参素、原儿茶醛、丹酚酸B)、320 nm(阿魏酸),柱温为30℃,进样量为10μl。结果:丹参素、原儿茶醛、阿魏酸、丹酚酸B质量浓度分别在9~144、0.5~8、0.65~10.4、221.25~3 540μg/ml范围内与各自峰面积呈良好的线性关系(r均为0.999 9);精密度、稳定性、重复性试验的RSD均≤1.90%;平均加样回收率分别为100.8%、100.1%、100.1%、99.4%,RSD分别为1.65%、2.87%、3.01%、2.05%(n=9)。结论:该方法简单易行、重复性好,可用于益心舒胶囊的质量控制。OBJECTIVE: To establish a method for the contents determination of tanshinol, protocatechuic aldehyde, ferulic ac- id and salvianolic acid B in Yixinshu capsule. METHODS: Dual-wavelength HPLC was performed on the column of Eclipse XDB-C18 with mobile phase of 0.5% phosphoric acid-methanol-acetonitrile (gradient elution) at the flow rate of 1.0 ml/min, the de- tection wavelength was 280 nm(tanshinol, protocatechuic aldehyde, salvianolic acid B) and 320 nm(ferulic acid), column tempera- ture was 30 ℃ and volume was 10 μl. RESULTS:The linear range of tanshinol, protocatechuic aldehyde, ferulic acid and salvianolic acid B were respectively 9-144 μg/ml(r=0.999 9),0.5-8 μg/ml(r=0.999 9), 0.65-10.4μg/ml (r=0.999 9) and 221.25-3 540 μg/ml (r= 0.999 9); RSDs of precision, stability and reproducibility tests were no more than 1.90%; the average recovery was respective- ly 100.8% (RSD=1.65% ,n=9), 100.1% (RSD=2.87% ,n=9), 100.1% (RSD=3.01% ,n=9) and 99.4% (RSD=2.05% ,n=9). CONCLUSIONS: The method is simple and reproducible, and can be used for the quality control of Yixinshu capsule.
