The invention belongs to the technical field of natural component extraction and preparation. The invention relates to a preparation method of periplaneta americana polypeptide extract, in particularto a preparation method of periplaneta americana polypeptide extract taking water as a medium, which sequentially comprises the following steps: mixing periplaneta americana medicinal raw materials with activated carbon powder, and pulverizing to obtain a pulverized material; dispersing the crushed material in water to obtain a dispersion liquid, and grinding the dispersion liquid to obtain an extracted mixture; and purifying and separating the periplaneta americana polypeptide extract from the extraction mixture. According to the method, water is used as a medium; the method has the advantages of avoiding of organic solvent residues, complete polypeptide extraction, low extraction cost, realization of adsorption of grease components by active carbon, avoiding of difficult separation caused by emulsification of an
