由于日益严格的环境法规，近年来超临界流体萃取（SFE）作为传统溶剂萃取的替代品在许多分析和工业过程中分离有机化合物得到了广泛的接受。在过去的十年中，超临界流体萃取技术已经成功地应用于从草药和其他植物中提取各种有机化合物。本文介绍了超临界流体萃取在样品制备、改性剂的选择、收集方法、在线耦合技术、避免机械问题的方法以及优化超临界流体萃取条件的方法等方面的实际应用。超临界流体萃取技术也可用于清除草药中的农药。通过对超临界流体萃取过程进行建模，可以获得有用的信息，以便更好地理解萃取过程、机理和优化萃取过程。随着公众对天然产物兴趣的增加，SFE可能成为研究草药，食品和农业样品的标准提取技术。(C)2001 Elsevier Science B.V.保留所有权利。
Due to increasingly stringent environmental regulations, supercritical fluid extraction (SFE) has gained wide acceptance in recent years as an alternative to conventional solvent extraction for separation of organic compounds in many analytical and industrial processes. In the past decade, SFE has been applied successfully to the extraction of a variety of organic compounds from herbs and other plants. This review article presents the practical aspects of SFE applications in sample preparation, selection of modifiers, collection methods, on-line coupling techniques, means for avoiding mechanical problems, and approaches to optimization of SFE conditions. SFE can also be used to clean up pesticides from herb medicines. SFE processes can be modeled to acquire useful information for better understanding of the extraction, mechanisms and optimization of the extraction procedures. With increasing public interest in natural products, SFE may become a standard extraction technique for studying herbal, food and agricultural samples. (C) 2001 Elsevier Science B.V.
