Abstract
Abstract The novel biologically active peptide valuable as an adjuvant for various medicaments and cosmetics as well as an additive for medicated wines and other edible products is prepared from the skeletal muscles of visceral muscles of the animals of the family Cervoidae such as Rangifer tarandus by decomposing the raw materials into low molecular weight peptides with a protease and collecting the active water-soluble portions therefrom by means of a molecular sieve or an ion-exchange resin.
