Periplaneta americana polypeptide extraction method

Abstract

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.

Description

technical field

[0001] The invention belongs to the technical field of extraction and preparation of natural components, and relates to a method for extracting Periplaneta americana polypeptide. Background technique

[0002] Periplaneta americana, also known as Feilian, has been recorded in "Shen Nong's Materia Medica". Modern research shows that its main active ingredients are polypeptides and biological enzymes, which have obvious effects of promoting tissue repair and regeneration, anti-tumor and anti-hepatitis. The marketed drugs with Periplaneta americana as the main raw material include Kangfuxin Liquid, Xinmailong, and Ganlong Capsules, etc., which have produced good economic and social benefits.

[0003] At present, the active ingredient polypeptide of Periplaneta americana usually uses high-concentration alcohol as the solvent medium to extract, then adds water to the relative system to separate, and finally uses activated carbon and macroporous resin to absorb the ...
