摘要

目的:建立RP-HPLC同时测定通脉复方水提液中5种成分的方法。方法:采用岛津Inertsil ODS-3色谱柱(250mm×4.6mm,5μm);以乙腈(A)-0.2%磷酸(B)为流动相,按梯度洗脱(015min,5%15%A;1550min,15%35%A),流速1mL/min,检测波长026min,240nm;2629min,260nm;2935min,334nm;3550min,286nm,柱温30℃。结果:马钱苷、羟基红花黄色素A、毛蕊异黄酮葡萄糖苷、毛蕊花糖苷、丹酚酸B分别在0.156 75.014 56μg(r=0.999 9),0.687 655.500 5μg(r=0.999 7),0.044 750.716 02μg(r=0.999 9),0.105 310.812 6μg(r=0.999 8),0.997 912.833 1μg(r=0.999 8)范围内呈良好线性关系;平均回收率分别为97.60%,98.95%,103.85%,96.60%,96.79%,RSD分别为0.42%,0.51%,1.65%,0.93%,1.19%。结论:该法操作简单,结果准确可靠,可为优选通脉复方提取工艺提供参考。
