The application discloses a preparation method of sophorolipids and application of the sophorolipids in anti-skin aging, and belongs to the technical field of fermentation. The sophorolipids are used in cell and animal experiments, and a skin aging cell and a mouse skin photoaging model are established by using a 311 nm UVB ultraviolet lamp. After testing, harmful active oxygen of the cell is reduced after the sophorolipids are used, and the thickening of the surface skin caused by skin photoaging is also relieved, which proves that the sophorolipids can not only relieve the symptoms of skin photoaging caused by long-term ultraviolet irradiation, but also prevent long-term stimulation of the ultraviolet to the mouse skin.

The application discloses two peptide segments derived from Cervus elaphus Linnaeus and application of the two peptide segments in promoting wound healing. Amino acid sequences of the two peptide segments are Gly-Ser-Phe-Pro-Trp-Gln-Ala-Lys (SEQ ID NO:1) and His-Ser-Trp-Ala-Val-Pro-Ser-Leu (SEQ ID NO:2) respectively. In-vitro experiments show that the two peptide segments can significantly promote proliferation and migration of human umbilical vein endothelial cells and mouse skin fibroblasts; in-vivo mouse acute wound model experiments prove that the two peptide segments can effectively accelerate the healing process of mouse acute wounds, have excellent biological activity of promoting acute skin wound healing, and have a good application prospect in development of drugs and functional products related to wound repair.
