Abstract: Preparation of the lyotropic liquid crystal template for separating and purifying natural pigment member could avoid the depuration process of samples.The request for the samples was not of a superior grade.Through the different pigment member formed different liquid crystal textures under the lyotropic liquid crystal template,natural pigment members could be separated and purified or impurities eliminated directionally.This method is one kind of high efficiency,low cost,safe operation and is a new separation purification technology suitable for the natural pigment industrialization production.This article discussed different liquid crystal textures,brought up suitable mechanism hypothesis(chemical reaction template theory and liquid crystal composition transformation physics adsorption theory)for this technology.

Key words: lyotropic liquid crystal template, separation and purification, natural pigment member, mechanism
