目的 :对注射用通脉灵进行质量标准的研究。方法 :采用薄层层析法对处方中药材进行了定性鉴别 ,并采用分光光度法对总黄酮进行了含量测定 ,采用比色法对总皂苷进行了含量测定。结果 :薄层色谱分离效果好 ,两种方法回收率RSD均小于 3%。结论 :该方法较简单 ,重现性好 ,可作该制剂质量控制标准。
Objective: To study the quality standard of Tongmailing for injection. Method : TLC was used to qualitatively identify Chinese herbal medicines. The content of total flavonoids was determined by spectrophotometry. The content of total saponins was determined by colorimetry. RESULTS : The effect of separation by TLC was good. The RSD of both methods was less than 3%. Conclusion: This method is simple and has good reproducibility. It can be used as the quality control standard of the preparation.
