Abstract: The extraction is the key operation step in the production of Chinese materia medica or the natural products. On the basis of brief description of traditional extracting technologies, extracting tech-niques appeared in recent five years are particularly reviewed in the principles, features, latest research and application results, and existing problems as well. These new techniques include supercritical fluid extrac- tion (SFE), continuous countercurrent extraction (CCE), microwave-assisted extraction (MAE), ultra- sound-assisted extraction (UAE), enzymatic treatment extraction (ETE), semi-bionic extraction (SBE), flooding extraction (FE), press extraction (PE), smashing tissue extraction (STE), heating-free extrac- tion (HFE), air explosion extraction (AEE), ultra-high pressure extraction (UHPE), etc. Further re- search topics and application prospects of these extracting techniques are also suggested.
