目的建立利通茶的质量标准。方法采用TLC法对方中的番泻叶进行定性鉴别;采用HPLC法测定制剂中陈皮的有效成分橙皮苷的含量。结果在TLC图谱中可检出番泻叶的特征斑点;橙皮苷在0.215-1.720μg内呈良好线性关系(r=0.9997),平均回收率为100.34%(n=6),RSD为1.2%。结论所采用的方法简便,准确,专属性强,重现性好。可用于利通茶的质量控制。
Purpose To establish the quality standards of Litong tea. Methods TLC method was used to qualitatively identify the senna; the content of hesperidin, the active ingredient of dried tangerine peel, was determined by HPLC. Results The characteristic spots of senna could be detected in the TLC chromatogram. Hesperidin showed a good linearity (r = 0.9997) in 0.215-1.720 μg with an average recovery of 100.34% (n = 6) and a RSD of 1.2% . Conclusions The method used is simple, accurate, specific and reproducible. Can be used for the quality control of Litong tea.
