超临界萃取技术在中药有效成分提取中的应用

近年来超临界流体萃取(supercritical fluid extraction,SFE)技术凭借萃取速度快、流程短、效率高、能耗少、可在较低温度下操作以及可以与GC、IR等分析手段联用等优越性已经成为萃取中药有效成分的重要技术手段.综述了SFE技术在中药有效成分如挥发性、萜类、生物碱、黄酮类及其苷、酚类、不饱和脂肪...

Application of supercritical fluid extraction technology in extraction of effective components in Chinese materia medica

In recent years, supercritical fluid extraction (SFE) technology has become an essential method in extraction of active ingredients for extraction of Chinese materia medica depending on fast extraction, short process, high efficiency, energy consumption, operating at lower temperature and being combined with GC and IR analysis methods. This article summarizes its applications in the separation and extraction of active ingredients, such as volatile components, effective components of terpene, alkaloid, active ingredients flavonoids, phenolic active ingredients, unsaturated fatty acids, active ingredient coumarin and so on. Finally, the development trends of the technology are prospected.
