超临界流体萃取（Supercriticalfluidextraction，SFE）技术是70年代末在工业上得到应用的一种新型分离技术，国外已广泛用于香料、食品、石油化工等领域[1]。随着基础理论和应用技术的研究，越来越清楚地显示它在制药工业，特别是中药化学成分革取方面的发展前景。本文就SFE的 Supercritical fluid extraction (SFE) technology is a new separation technology applied in the industry in the late 1970s. It has been widely used in the fields of spices, food, petrochemical and other fields [1]. With the study of basic theory and applied technology, it is increasingly clear that it has a promising future in the pharmaceutical industry, especially the acquisition of chemical constituents of traditional Chinese medicine.
