艳友茶质量标准研究

Study on quality standard for Yanyou Tea

目的建立艳友茶的质量标准。方法采用薄层色谱法对处方中三七、荷叶进行定性鉴别；用HPLC法测定芍药苷的含量。结果在TLC定性鉴别中三七、荷叶分离度好，专属性强；芍药苷在0．04704～5．88μg内有良好的线性关系，相关系数r=0．9999（n=5）；平均加样回收率为98．95％，RSD为2．16％（n=9）。结论该方法简便、准确，重复性好，可作为艳友茶的质量控制方法。

OBJECTIVE To establish a quality for Yanyou Tea. METHODS Panax Notoginseng and Folium Nelumbinis in Yanyou Tea were identified by TLC.The content of Paeoniflorin was determined by HPLC. RESULTS Panax Notoginseng and Folium Nelumbinis could be identified by TI,C;Paeoniflorin showed a good linearity in the range of 0. 04704- 5.88μg（r = 0. 9999, n = 5） ; The average recovery was 98.95 % with RSD of 2.16 % （n = 9）. CONCLUSION The method are available with a reproducibility and could control the quality of Yanyou Tea.
