云厚朴两种提取方法的比较研究

Comparative Study of Two Extraction Methods for Magnolia Rostrata

目的:选择云厚朴的提取工艺。方法:采用HPLC法测定两种提取物中厚朴酚的含量。结果:乙醇回流法与超临界CO2萃取法(SFE-CO2)提取厚朴酚得率分别为2.63%、2.40%,浸膏得率分别为29.3%、10.1%,厚朴酚在浸膏中的含量为9.1%、23.7%。结论:超临界CO2萃取法优于乙醇回流提取法。

To optimize the extaction technology of Magnolia rostrata. Methods： The contents of magnolol in two kinds of extracts were determined by HPLC. Results： Ethanol reflux and SFE - CO2 extraction Magnolol yield of 2.63 percent, 2.40 Percent; to extract a rate of 29.3 percent, 10. 1 percent; Magnolol in order to extract the contents9. 1% , 23.7%. Conclusions： SFE - CO2 method is superior to ethanol reflux extraction.
