摘　　要：亚临界水萃取技术是近年来化学成分提取新技术,在中药领域主要用于挥发性成分的提取、分离。影响提取效率的关键因素主要有压力、温度、萃取时间以及夹带剂。亚临界水萃取技术与常用的提取方法相比具有以下优点:高效、低成本、无污染等,在使用过程中通过改变萃取参数,对萃取溶媒的极性进行微调,可以选择性的萃取出不同极性的化合物,有机溶剂的参与将大大增加水溶媒的萃取范围,同时低碳、环保的大生产将是该技术迅速兴起的契机。The subcritical water extraction technology is a new technology in recent years and mainly used for the extraction and separation of volatile components in the field of traditional Chinese medicine（ TCM）. The key factors influencing the extraction efficiency mainly include pressure,temperature,extraction time and entrainer. Compared with the commonly used extraction methods,subcritical water extraction technology has the following advantages： high efficiency,low cost,no pollution,etc. By changing the parameters of extraction in the process of use and slight adjustment of solvent polarity can selectively extract compounds. Organic solvent participation will greatly increase the scope of water solvent extraction. Low carbon and environmental mass production will be the technology grew rapidly.
