ABSTRACT
China consumes and exports traditional Chinese medicinal resources the most in the world. However, we cannot anchor our hope on field production of traditional Chinese medicinal materials and their active ingredients, due to limited land resources. Therefore, the development of biotechnology is of great importance for China to solve the problem of traditional Chinese medicinal resources. Plant cell culture is an important approach for the sustainable development of precious medicinal resources. This essary summarizes the optimization of conditions for medicinal plant cell culture, the regulation of secondary metabolic pathways and cell bioreactor culture, and realizes that the authentic commercial production of more medicinal plants requires efforts from all aspects.
