摘要(Abstract):

中草药和天然植物有效成分的提取分离是天然药物生产过程中最为关键的环节之一。近年来 ,随着中药现代化进程的加速 ,越来越多的新技术正被逐步采用 ,其中 ,微波协助萃取 (microwave assistedextraction ,MAE)是在传统有机溶剂萃取的基础上发展而来的 ,无论是萃取速度、萃取效率还是萃取物质量均优于常规工艺 ,并以其投资少、设备简单、适用范围广、选择性高、重现性好、无污染等特点而受人瞩目。作者综述了MAE技术的作用原理、特点及其在黄酮类、苷类、多糖、萜类、挥发油等天然产物提取中的最新研究进展 ,并展望了其发展前景。
The extraction and separation of effective components from Chinese herb and natural plant is one of the most important processes of natural medicine production. Recently,more and more advanced techniques have been used in the field of modern Chinese medicines,for example,microwave-assisted extraction (MAE). Developed on the base of traditional extracting technology using by organic solvents,MAE is of higher extraction rate and efficiency and better extract quality,as well as few investment,simple equipment,wide adaptability,high selectivity,good fidelity and no pollution. This paper mainly reviews the action principle and characteristic of MAE and its application in the extraction of natural products such as flavonoids,glycosides,polysaccharides,terpenoids and essence. Otherwise,the developing foreground of MAE is also prospected here.
