在过去的十年中，在分析实验室中使用微波辅助萃取和加压溶剂萃取技术的兴趣越来越大。本文简要介绍了这两种方法，并报道了它们在天然产物提取中的应用。讨论了溶剂性质、体积、温度、时间、基质粒度等参数对反应的影响。通过大量的实例证明，这两种技术都可以减少溶剂消耗和缩短提取时间，而分析物的提取率相当于甚至高于传统方法。版权所有:John Wiley Sons, Ltd。
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.
