不同采收时期白术质量测定.docVIP

不同采收时期白术质量测定[摘要] 目的：探讨不同采收时期白术的质量，并进行统计及比较。方法：选取浙江产白术，将其根据采收时期的不同进行分组，并根据其采收时期及生长年限，应用高效液相色谱法对白术进行白术内酯Ⅰ、白术内酯Ⅲ及苍术酮含量的测定，并将测定结果进行统计及比较。结果：经研究比较发现，随着年份的增加，白术内酯Ⅰ、白术内酯Ⅲ及苍术酮的含量均呈现上升趋势，而且11月上旬采摘的白术的白术内酯Ⅰ、白术内酯Ⅲ及苍术酮的含量高于其他月份，经比较，P均＜0.05，差异均有统计学意义。结论：不同采收时期白术的质量明显不同，购买时以3年生11月上旬采摘者质量最佳。 [关键词] 不同采收时期；白术；白术内酯Ⅰ；白术内酯Ⅲ；苍术酮 [中图分类号] R286.0[文献标识码] A [文章编号] 1674-4721（2011）01（b）-042-02 Headed atractylodes quality determination at different harvest period LIN Jiashou (The Center Hospital of Traditional Chinese Medicine of Foshan, GuangDong Province, Foshan 528000, China) [Abstract] Objective: To explore the quality of atractylodes at different harvest period, and to compare and analyse the results. Methods: The atractylodes in Zhejiang were grouped according to the different harvest period, and the atractylodes lactone Ⅰ, atractylodes lactone Ⅲ and atractylon of the atractylodes were detected by high performance liquid chromatography according to the harvest period and growth years, and the detection were analyzed and compared. Results: With the years increasing, contents of atractylodes lactone Ⅰ, atractylodes lactone Ⅲ and atractylon of the atractylodes increased, and the contents of atractylodes lactone Ⅰ, atractylodes lactone Ⅲ and atractylon of the atractylodes at beginning of November were higher than those at other months, P＜0.05, there were significant differences. Conclusion: The quality of atractylodes at different harvest period are obviously different, the three years’ old atractylodes at beginning of November is the best.
