Momordica charantia peptide for wrinkle relieving and repairing and preparation process thereof

The invention relates to a momordica charantia peptide for wrinkle relieving and repairing and a preparation process thereof. The preparation process comprises the following steps: (1) hulling momordica charantia seeds, and performing grinding; (2) performing supercritical CO2 fluid extraction; (3) adjusting the pH value of the mixture to 9-10 with a sodium hydroxide aqueous solution having the concentration of 0.05-0.15mol/L, performing stirring and extracting at 30-60 DEG C for 2-6 hours, performing centrifuging, separating precipitate from supernatant liquid to respectively obtain extractedslag and an extracted liquid; and (4) performing ultrafiltration on the extracted liquid with an ultrafiltration membrane with molecular weight cut-off being 8000-15000Da, and performing freeze-drying. According to the momordica charantia peptide for wrinkle relieving and repairing and the preparation process, through a great deal of researches, a practical and efficient preparation process is found out, and a novel momo
