In the last 10 years there has been an increased interest in using techniques involving microwave-assisted extraction and pressurised solvent extraction in analytical laboratories. This review gives a brief overview of both methods, and reports on their application to the extraction of natural products. The influence of parameters such as the nature of the solvent and volume, temperature, time and particle size of the matrix is discussed. Through numerous examples, it is demonstrated that both techniques allow reduced solvent consumption and shorter extraction times, while the extraction yields of the analytes are equivalent to or even higher than those obtained with conventional methods.
在过去十年中，分析实验室对采用微波辅助萃取和加压溶剂萃取技术的兴趣与日俱增。本综述简要概述了这两种方法，并报告了它们在天然产物萃取中的应用。讨论了溶剂性质、体积、温度、时间和基质粒径等参数的影响。通过大量实例表明，这两种技术都能减少溶剂消耗并缩短萃取时间，而分析物的萃取产率与传统方法相当甚至更高。
