The invention belongs to the technical field of natural component extraction and preparation, and relates to a periplaneta americana polypeptide extraction method. The method comprises the following steps of removing most of grease by adopting a solvent polarity progressive increase extraction method, and then removing a small amount of residual grease, solvent residues and pigments by adopting aresin adsorption method. In an obtained polypeptide product, the grease residues and organic solvent residues used in the technological process cannot be detected, the fishy smell in the product is eliminated, the content of the product is increased, and the product quality is greatly improved. The method has relatively good market application prospects and economic benefits. 本发明属于天然成分提取制备技术领域，涉及一种美洲大蠊多肽提取方法，本法采用溶剂极性递增萃取法去除绝大部分油脂，再通过树脂吸附法去除少量残留油脂、溶剂残留和色素，在所得到的多肽产品中，检测不到油脂残留以及工艺过程中使用的有机溶剂残留，也消除了产品中的腥臭味，提高了产品含量，产品质量得到极大提高。本发明具有较好的市场应用前景和经济效益。
