Abstract
目的:建立太平糖克丸中马钱苷的含量测定方法。方法:采用高效液相色谱法,Prontosil 120-5-C18柱(250mm ×4.6mm,5μm),流动相为四氢呋喃-乙腈-甲醇-0.05%磷酸溶液(1∶8∶4∶87);流速1.0mL/min;检测波长236nm;柱温30℃;进样量10μL。理论板数按马钱苷峰计算应不得低于4000。结果:马钱苷对照品进样量在0.0302 g~3.0177 g范围内,进样量与峰面积呈良好的线性关系(r=0.9999),马钱苷平均加样回收率为97.24%,RSD值1.55%(n=6)。结论:本方法操作简便,准确可靠,专属性强,重现性好。适宜用于测定太平糖克丸中马钱苷的含量。
