title: [Microorganisms of special herb-glycosidases and their fermentation, enzyme properties].
abstract: Herb-glycosides are main active elements of Zhongcaoyao (Chinese traditional medicines, Chinese medical herbs). However, the herb-glycoside structures are not optimal active structure for the human bodies. After orally taken up, the herb-glycosides of Zhongcaoyao could be changed into other more active structures by the digestive system such as enzymes and intestinal microorganisms; then degraded and absorbed in the human body and play the real role of pharmic effect; but only a small amount could be changed and controlled by circadian state of the human body. If this biochange of herb-glycosides to more active structures in vivo was finished in vitro, it is very useful for the development of the Chinese traditional medicines, new plant medicines, health food, and function cosmetics. To biotransformate herb-glycosides to more active structure, this paper introduced the studies of author's team on the new microorganism isolation of the special herb-glycosidases and enzyme fermentation, the special enzyme purification and characterization.
