Abstract
目的 建立同时测定柏子养心丸中阿魏酸、肉桂酸和桂皮醛含量的高效液相色谱(HPLC)法.方法 色谱柱为Agilent Eclipse SB-C18柱(250 mm×4.6 mm,5μm),流动相为乙腈(A)-0.1%磷酸溶液(B),梯度洗脱,流速1.0 mL/min,检测波长290 nm,柱温30℃.结果 阿魏酸、肉桂酸、桂皮醛进样量分别在0.0938~1.8760μg(r=0.9999),0.0599~1.1980μg(r=0.9999),0.127~2.540μg(r=0.9999)范围内与峰面积线性关系良好;平均回收率分别为98.65%,98.67%,99.02%,RSD分别为0.88%,1.12%,1.04%(n=6).结论 该方法简单、准确、重复性好,可用于柏子养心丸的质量控制,测定结果反映出不同厂家生产的柏子养心丸质量有差异.
