Efficient storage of large amounts of fresh Dioscorea zingiberensis C. H. Wright (DZW) tubers with the minimum loss of
useful components is important in diosgenin production. In this study, the components changes, in particular the saponins
change of DZW tubers during storage in four different conditions were investigated. Saponins were preliminarily identified
through liquid chromatograph-mass spectrometer (LC-MS). Results revealed that plant endogenous enzymes, compared with
the other factors concerned most significantly affected diosgenin yield by modifying the composition and content of steroidal
saponins. Glycosyl transferase, a plant endogenous enzyme, converted furostanol glycoside to its spirostanol type. Some
glycosidases further participated in the biodegradation of polysaccharides at the C-3 position to their corresponding
secondary glycosides. Moreover, the environmental microbes also played an important role in DZW tuber storage by
secreting enzymes with similar functions. It exhibited some synergistic effect with the plant endogenous enzymes in
affecting the components of DZW tubers during storage. This work, to the best of our knowledge, presented the first
relatively systematic study of the effects of plant endogenous enzymes and environmental microbes on the storage of DZW
tubers, and could provide a preliminary theoretical guidance to the volume storage of fresh DZW tubers in industry.
