目的 :建立了精制冠心片的含量测定方法。方法 :采用HPLC法测定芍药苷的含量。结果 :三批样品芍药苷的含量限度规定为不得少于 1.5mg/片 ,平均回收率为10 0 .8% ,RSD =1.0 %。结论 :方法简便可行 ,重现性好 ,可很好地控制精制冠心片的内在质量。
Objective : To establish a method for determination of refined coronary heart slices. Methods: The content of peoniflorin was determined by HPLC. Results: The content limit of paeoniflorin in three batches of samples was not less than 1.5 mg/tablet, and the average recovery was 100.8%. RSD was 1.0%. Conclusion: The method is simple and feasible, with good reproducibility, and can control the intrinsic quality of refined coronary heart chip.
