摘要
目的建立同时测定大黄药材中5种蒽醌类衍生物(芦荟大黄素、大黄酸、大黄素、大黄酚和大黄素甲醚)含量的方法,优化大黄蒽醌的超声提取工艺。方法采用反相高效液相法,色谱柱:W aters C18柱(250 mm×4.6 mm,5μm);流动相:甲醇-乙腈-0.01%磷酸溶液(3∶5∶2);柱温:25℃;流速:1.0 m l/m in;检测波长:225 nm。结果5种游离蒽醌均具有较宽的线性范围且呈良好的线性关系(R2=0.998 7~0.999 7),平均回收率为92.79%99.28%,日内精密度为0.65%1.71%,日间精密度为2.52%3.46%。结论该方法成功应用于大黄活性物质的提取工艺优化,根据所建立的方法测得的5种游离蒽醌含量,确定了大黄蒽醌的最佳超声提取工艺为:以70%乙醇为溶剂、料液比为1∶30(g∶m l)、超声提取2次、每次提取20 m in。
