PERIPLANETA AMERICANA EXTRACT, PREPARATION METHOD THEREFOR AND USE THEREOF

摘要

Disclosed are a Periplaneta americana extract and the preparation method therefor. The method uses acetone for reflux and water for extraction. The resulting extract is concentrated, to which ethanol is added, then ethanol is recovered to obtain a filtrate. The filtrate is then processed through an adsorption resin column, and the effluent liquid is collected until the ninhydrin reaction is negative. The liquid is processed through a polyamide column, and the effluent liquid is collected until the ninhydrin reaction is negative. The effluent liquid is concentrated and dried. Also disclosed is the use of the Periplaneta americana extract in the manufacture of an inductive solution for orientedly inducing the differentiation from mesenchyme stem cells to epidermal cells.
