Advances in new technologies applying to Chinese materia medica extraction / 中草药

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 techniques 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 extraction(SFE),continuous countercurrent extraction(CCE),microwave-assisted extraction(MAE),ultrasound-assisted extraction(UAE),enzymatic treatment extraction(ETE),semi-bionic extraction(SBE),flooding extraction(FE),press extraction(PE),smashing tissue extraction(STE),heating-free extraction(HFE),air explosion extraction(AEE),ultra-high pressure extraction(UHPE),etc.Further research topics and application prospects of these extracting techniques are also suggested.
