6种不同产地乌药中乌药醚内酯的HPLC法含量测定

The Determination of Radix Linderae Ether Lactone's Content from Radix Linderae of Six Different Areas

目的:测定不同产地乌药中乌药醚内酯的含量,确定乌药乌药醚内酯的最佳产地,为合理利用该药材提供依据。方法:以乌药醚内酯为标准品,采用反向高效液相色谱法测定乌药中乌药醚内酯的含量。结果:不同产地乌药中的乌药醚内酯含量差异较大,以浙江台州、江西,所产含量较高,其中浙江台州最高,为3.72mg/g。结论:浙江台州可以定为乌药乌药醚内酯的最佳产地。

Objective ： To determine the contents of Linderane in Lindera aggregata （ Sims ） Kosterm produced in different areas and find the best producing area. Methods： The contents of Linderane in Lindera aggregata （Sims） Kosterm were determine by a RP - HPLC method. Results ： It shows that the content varies greatly in different producing areas. The content of Linderane is higher in Zhejiangtiantai,Jiangxi, among which the content in Zhejiangtiantai is the hightest （3. 72mg/g）. Conclusion： Zhejiangtiantai can considered as the optimal producing area of Linderane in Lindera aggregata （Sims） Kosterm.
