摘要

目的: 提高榄葱茶的质量标准。方法: 采用TLC对制剂中青果、紫苏叶、生姜进行定性鉴别

采用HPLC测定迷迭香酸和没食子酸的含量。结果: TLC鉴别斑点清晰

分离效果良好

阴性对照无干扰;迷迭香酸在0.098~4.912 μg呈线性关系(r=0.999 9)

平均回收率为100.24% (RSD 2.9%)。没食子酸在0.100 2~1.503 0 μg呈线性关系(r=0.999 97)

平均加样回收率为99.02% (RSD 1.8%)。结论: 所建立的方法专属性强、灵敏度高、重复性好

有利于该制剂的质量控制。

Abstract

Objective: To improve the quality standard of Lancong Cha. Method: Canarii Fructus

Perillae Folium and Zingiberis Rhizoma Recens in the recipe were identified by TLC. The contents of rosmarinci acid and gallic acid were determined by HPLC. Result: The TLC spots were clearly and separated well

and the negative control did not impose any disturbance. Rosmarinci acid had good linearity in a range of 0.098-4.912 μg(r=0.999 9). The average recovery was 100.24%

and RSD was 2.9%. Gallic acid had good linearity in a range of 0.100 2-1.503 0μg (r=0.999 97). The average recovery was 99.02%

and RSD was 1.8%. Conclusion: The method was specific

sensitive and repeatable

can be used to control the quality of Lancong Tea better.
