生物碱的超临界流体萃取研究进展

Progress of Study on Extraction of Alkaloids by Supercritical Fluid

综述了超临界流体萃取技术应用于生物碱分离的研究进展,分析了影响生物碱提取效果的各个因素,除温度、压力、溶剂、萃取时间等常见因素外,碱化剂能够改善生物碱的分离效果,夹带剂的使用则提高了超临界流体的萃取能力。

This article summarizes the progress of the study on the application of the technology of supercritical fluid extraction to the isolation of alkaloids, and analyzes the factors that may affect the result of the isolation. It also indicates that besides the general factors, such as temperature, pressure, solvent and the time of extraction, extraction result can be improved by adding alkalis while the extraction capacity of supercritical fluid can be enhanced due to the use of cosolvents.
