Abstract: The paper introduced the application of biological technology in the screening and breeding yellow ginger varieties with the high content of diosgenin and the extraction process. The paper compared the effect of different extraction methods on the yield of diosgenin and analyzed the main factors which influence the yield with the biological methods. Enzyme hydrolysis has obvious advantages in extracting diosgenin from yellow ginger in the yield and environmental protection compared with the traditional acid hydrolysis. Therefore, the study proposes new thoughts of development and evaluation method of diosgenin from yellow ginger using biological technology comprehensively. It has practical guidance to promote the industrialization of diosgenin.

Key words: diosgenin, biotechnology, enzymatic hydrolysis, evaluation methodology
