目的建立上感冲剂质量标准。方法采用薄层色谱法对处方中的板蓝根、大青叶进行定性鉴别,用高效液相色谱法测定处方中连翘中连翘苷的含量。结果薄层色谱法阴性对照无干扰;连翘苷在14.016～70.080μg/ml。表明连翘苷在范围内呈良好的线性关系(r=0.9999,n=5),平均回收率为98.0%,RSD=0.86%(n=9)。结论所建立的方法可准确地进行定性、定量检测,可用于该制剂的质量控制。 Objective To establish quality standards for Shanggan granules. Methods Radix Isatidis and Folium Isatidis were identified by thin-layer chromatography. The content of forsythin in Forsythia suspense was determined by high performance liquid chromatography. RESULTS TLC-negative control did not interfere; forsythin ranged from 14.016 to 70.080 μg/ml. It was shown that forsythin showed a good linear relationship in the range (r=0.9999, n=5), the average recovery was 98.0%, and RSD was 0.86% (n=9). Conclusion The established method can accurately perform qualitative and quantitative detection and can be used for quality control of the preparation.
