摘要
超临界CO2萃取具备高效、节能、清洁、操作条件温和等优点,受到越来越多的关注,正逐渐成为取代传统溶剂法提取活性物质的绿色工艺之一。为了进一步了解超临界CO2萃取技术的应用现状,该文介绍了超临界流体萃取(SFE)技术的原理,依据提取天然产物的类型综述了该技术在植物精油、天然色素、生物碱提取中的应用,与传统溶剂方法相比所具有的优势,并展望了其工业化应用前景,为超临界CO2萃取技术在天然产物中的应用提供参考和借鉴。
Supercritical CO2 （SC-CO2） extraction has the advantages of efficient, energy saving, clean, mild operation condition. It has received a growing number of attentions, and it has become one of green extraction technologies that replace the traditional solvent method. To know more about the application status of SC-CO2, the paper summarized the principle of supercritical fluid extraction technology, the application of SC-CO2 in the fields of essential oils, natural pigments, alkaloid extraction based on the types of natural products. The advantage of the method was compared with traditional solvent method, and the industrial application was prospected, to provide reference for the further application of SC-CO2 in natural products.
