摘要
目的:提升益肝片的质量标准。方法:采用薄层色谱法(TLC)鉴别益肝片中的板蓝根、虎杖;采用高效液相色谱法(HPLC)对益肝片中的(R,S)-告依春和大黄素进行含量测定。结果:通过TLC鉴别板蓝根、虎杖,相应斑点清晰、分离度好,阴性无干扰。(R,S)-告依春在进样量0.03~0.15μg范围内与峰面积线性关系良好(r=0.9998),平均加样回收率为97.05%,大黄素在进样量0.0495~0.297μg范围内与峰面积线性关系良好(r=1.0000),平均加样回收率为99.24%。结论:本质量标准能有效鉴别益肝片中的板蓝根、虎杖,也能有效测定(R,S)-告依春和大黄素的含量,且该法简便、可靠、重复性好,可用于益肝片的质量控制。
Objective:To improve the quality standard of Yigan tablet.Methods:Isatidis Radix and Polygonum cuspidatum in Yigan tablet were identified with thin layer chromatography(TLC).The content of(R,S)-Goitrin and Emodin in Yigan tablet was determined by high performance liquid chromatography(HPLC).Results:The spots of Isatidis Radix and Polygonum cuspidatum were clear,well separated and negative without interference when identified.The peak area of(R,S)-Goitrin ranged from 0.03μg to 0.15μg had perfect linear relationship(r=0.9998)with the injection volume,and the average recovery rate was 97.05%;the peak area of Emodin ranged from 0.0495μg to 0.297μg had perfect linear relationship(r=1.0000)with the injection volume,and the average recovery rate was 99.24%.Conclusion:The quality standard can not only effectively identify Isatidis Radix and Polygonum cuspidatum but also can effectively determine the content of(R,S)-Goitrin and Emodin.The method is simple,reliable and repeatable,and can be used for the quality control of Yigan tablet.
