A process for producing an arginine-rich peptide mixture and the application thereof in cervical cancer therapy is provided. The process includes the following steps: A suspension of walnut meal and egg albumin is pretreated with ultrahigh pressure, and then digested by alkaline proteinase and papain in separated steps with the ultrasonic and microwave-assisted extraction. The peptides of interest are isolated from filtration supernatant obtained after the enzyme digestion by reversed phase high-performance liquid chromatography. By using the peptide mixture as a template, acrylic acid and methyl acrylic acid as functional monomers, triethylene glycol dimethacrylate as cross-linking agent, and isopropylthioxanthone in acetone as a photoinitiator, polymerization is induced by ultraviolet light to form a surface imprinted membrane for isolating and enriching the peptides of interest from the supernatant. The arginine content in the peptide mixture is more than 18%. The arginine-rich peptide mixture is able to strongly suppress the proliferation of human cervical cancer Hela cells. The approach is applicable to reduce the cost of production and speed up the commercialization of large-scale production.
