醌类化合物的超临界流体萃取研究进展

Progress in Extraction of Quinones by Supercritical Fluid

综述了国内近20年来超临界流体萃取技术应用于醌类化合物分离的研究进展,重点介绍了超临界流体萃取技术在中草药中醌类化合物的分析测定方面的应用,分析了影响醌类成分提取效果的主要因素,优化萃取温度和萃取压力能够改善琨类化合物的分离效果,夹带剂的使用则有效地提高了超临界流体的萃取能力。

xProgress in supercritical fluid extraction of quinines in 20 years in China is reviewed. The application of the technology of supercritical fluid extraction to the isolation of quinines is chiefly introduced. The main factors that may affect the result of the isolation are also analyzed; extraction result can be improved by optimizing temperature and pressure while the extraction capacity of supercritical fluid can be enhanced due to the use of modifier.
