Abstract
目的研究解郁舒心片中黄酮类化合物含量的测定方法。方法采用UV法测定总黄酮的含量,HPLC法测定芦丁和金丝桃苷的含量。结果总黄酮在7.5~45.3μg/mL与420nm处的吸收度呈良好的线性关系,平均回收率为100.36%,RSD2.58%。采用shim-packCLC-ODS色谱柱,以水-乙腈-磷酸(825︰175︰1)为流动相,芦丁和金丝桃苷与相邻组分分离良好,分别在0.45~4.50μg,0.06~0.60μg线性关系良好,平均回收率为100.22%,101.22%,RSD为1.74%,1.70%。结论 UV法和HPLC法的结合应用,可对解郁舒心片中黄酮类成分的含量进行有效的控制。
