The invention discloses a method for converting furan steroid saponin in a plant body into spiral steroid saponin and producing saponin, which comprises the following steps of: cleaning and selecting fresh leaves of related plants, cutting into pieces, soaking in cold water twice, and combining solutions; performing suction filtration or centrifugation; obtaining a crude enzyme solution; the method comprises the following steps of: adding the saponin into mixed slurry of dioscorea zingiberensis and the like, converting for 1-72 hours, judging whether conversion is complete or not by using a reagent E and a reagent A in combination with a thin-layer chromatography method, reproducing saponin, and comparing the saponin with saponin produced by a conventional pre-fermentation acid hydrolysis method. The method disclosed by the invention has the advantages that the furan steroid saponin in the dioscorea rhizome group plants is converted into the spiral steroid saponin by utilizing the leaching solution of the fresh leaves of the dioscorea rhizome group plants in China, and the saponin is produced and prepared. Compared with the traditional process, the spiral steroid saponin has the advantages of higher yield, lower acid consumption, lower pollution and shorter process time.

This invention relates to a method for preparing and applying a fermented product of Bifida Ferment Lysate and Dioscorea Oolong with enhanced moisturizing and anti-aging effects, belonging to the field of microbial fermentation technology. This invention discloses a *Bifidobacterium longum*, the nucleotide sequence of which is shown in SEQ ID NO: 1. This invention utilizes *Bifidobacterium longum* HJ-005 to ferment *Dioscorea opposita* and *Dioscorea opposita* to prepare a *Bifida Ferment Lysate* fermented product of *Dioscorea opposita*, simultaneously increasing the content of absorbable diosgenin, anthocyanins, arginine, and organic selenium, with better effects compared to other lactic acid bacteria. It can significantly reduce the water loss and shrinkage of zebrafish embryos, exhibiting a moisturizing effect, and can significantly promote the expression of zebrafish type I collagen and Elna genes, promoting collagen and elastin regeneration, thus possessing anti-aging effects and can be used as a new raw material for cosmetics.

The present application provides a protein derived from Dioscorea zingiberensis, its encoding gene and application. The protein provided by the present application is selected from at least one of a) and b): a) a protein with an amino acid sequence as shown in SEQ ID NO: 2; b) a fusion protein obtained by connecting a tag to the N terminal and / or C terminal of the protein as shown in SEQ ID NO: 2. The protein provided by the present application has P450 enzyme activity, and experiments have verified that the co-expression of the protein encoding gene and other diosgenin synthesis genes in yeast cells can significantly improve the biosynthesis efficiency of diosgenin, thereby providing a key gene resource for the biosynthesis of diosgenin.

The invention relates to the technical field of functional component microencapsulation, and discloses a dioscorea batatas anthocyanin yeast microcapsule as well as a preparation method and application thereof. The dioscorea batatas is rich in anthocyanin, has remarkable biological activities such as oxidation resistance, inflammation resistance and cardiovascular protection, but is poor in stability and low in bioavailability in a natural state. According to the microcapsule prepared by the invention, the yeast is used as a wall material, and the dioscorea batatas anthocyanin is accurately embedded in the yeast to form microcapsule particles with stable structure and uniform particle size. In the preparation process, key parameters such as the raw material ratio, the reaction temperature and the stirring time are optimized, so that the anthocyanin is efficiently loaded, and the microcapsule has excellent performance. The microcapsule can be used as a natural antioxidant and a coloring agent in the field of food, so that the food quality and safety are improved, and the shelf life is prolonged; in the field of medicine, the compound can be used for developing functional preparations for preventing and treating chronic diseases; in the field of cosmetics, the anti-aging composition can be added into skin care products to exert the anti-oxidation and anti-aging effects, and the market application prospect is extremely wide.
