摘　　要：目的建立清通浓缩袋泡剂的质量控制方法。方法用薄层色谱法对清通浓缩袋泡剂中的主要药味大黄、番泻叶进行定性鉴别;并用紫外分光光度法以大黄素及总番泻苷为指标进行含量测定。结果薄层色谱中斑点清晰,易于识别。大黄素在2mg～14mg/L(R=0.9996)范围内线性范围良好,平均回收率为98.64%,RSD为0.70%,且紫外分光光度法精密度、重现性良好。结论本方法可有效地控制清通浓缩袋泡剂的质量。Objective： To develop effective methods for Qingtong tea bag. Methods： TLC was performed to identify Radix Et Rhizoma Rhei and Cassia angustifolia vahl. The content of emodin and sennoside were determined by UV-spectrophotometry. Results： The linear range of emodin was 2mg-14mg/L, r=0.9996. The average recovery was 98.64% with RSD of 0.70%. Conclusion： The method is simple, fast and accurate. It can be used for the quality control of Qingtong tea bag.
