摘要
目的:优选麻黄汽爆预处理后麻黄碱的提取工艺。方法:采用汽爆技术对麻黄草进行预处理,通过提取试验确定汽爆参数,然后采用正交实验法,确定汽爆麻黄中麻黄碱的提取工艺。通过电镜观察汽爆前后麻黄草组织结构变化情况,对汽爆原理及提取过程进行初步分析。结果:麻黄汽爆预处理后,麻黄碱最佳提取工艺为:100℃,90 min,浸提3次。结论:该提取工艺可提高麻黄碱的提取收率。
AIM：To optimize ephedrine extraction procedure from steam exploded Ephedra sinica was preliminarily treated by the steam explosion, and the steam explosion parameters were determined by extraction tests. Orthogonal design was used to optimize the extraction conditions. In addition, by use of the electric microscope, the configuration of Ephedra sinica and steam exploded ephedrine steam explosion and the extraction process. RESULTS：The sinica was achieved in the experiment conditions of 100 ℃, 90 min, reported sinica was analyzed to characterize optimal extraction of steam exploded and 3 times extraction. CONCLUSION： The extraction procedure could increased the extraction efficiency of ephedrine
