     摘要：目的为降脂袋泡茶提供质量控制的方法。方法采用TLC法对大黄、金银花分别进行了色谱鉴别，采用HPLC测定了复方大黄中大黄素的含量。TLC鉴别方法专属性强。用HPLC法对含量大黄素进行了定量分析，流动相为甲醇水磷酸(70∶30∶0.01)，流速1.0 ml/min，检测波长254 nm。结果大黄素在0.01～0.22 μg之间有良好的线性关系，平均回收率为101.19%，RSD为2.87%。结论该质量标准可有效地控制降脂袋泡茶的质量。

    Abstract:ObjectiveTo establish the quality standard for Jiangzhi Bagged Tea. MethodsThe Herba Lysimachiae and Radix et Rhizoma Rhei in Jiangzhi Bagged Tea were identified by TLC. Emodin of the Tea was determined by HPLC. The mobile phase was methanol-water-phosphatic acid(70∶30∶0.01), flow rate was 1.0 ml/min. The detection wavelength was at 254 nm. ResultsThe linear range of Emodin was 0.01～0.22 μg, the average recovery rate was 101.19% and RSD was 2.87%, respectively. ConclusionThis method is simple, reliable and accurate, and it can be used for quality control of Jiangzhi Bagged Tea. ......
