    摘要: Disclosed is a novel peptide, which is a highly functional peptide derived from a natural fermentation product exhibiting an anti-wrinkle activity. A tetrapeptide consists of an amino acid sequence of glycine (Gly)-glutamine (Gln)-valine (Val)-serine (Ser) (SEQ ID NO: 1). The peptide is synthesized by utilizing 2-(4-nitrophenyl) sulfonylethoxycarbonyl-amino acid (Nsc-amino acid) as an intermediate. The anti-wrinkle activity is exhibited through the inhibition of elastase. The anti-wrinkle activity is exhibited through collagen synthesis. A method of preventing skin wrinkle, includes applying to a skin a tetrapeptide consisting of an amino acid sequence GQVS (SEQ ID NO: 1).
