Abstract:

Saponins are a group of secondary metabolites occurring constitutively in most higher plant species, which have wide potential application in development of medicine, plant\|derived pesticides, health  products and nourishment. However, the contents of saponins are low and unstable in plants, which seriously affects the development and utilizations of these compounds. Therefore, regulation biosynthesis of saponins and improvement of its production have attracted more and more attention. This paper expounded the biosynthetic pathway, cultivation technology, genetic engineering, cell engineering and hairy root cultivation, and the research progress made in its synthesis of regulation. In addition, this paper also summarised the problems existing in this area and prospects the future research orientation.
