Abstract

The invention discloses a refined plant polysaccharide, a preparing method and application to preparing cosmetics. The refined plant polysaccharide is prepared through the following steps of preparingpetasites japonicus total polysaccharides through a water extraction and alcohol precipitation method, dissolving the petasites japonicus total polysaccharides in deionized water to prepare a sampling solution, putting the sampling solution onto a DEAE-Sepharose Fast Flow chromatographic column, conducting elution sequentially through sodium chloride solutions with the concentrations of 0, 0.2 and 0.5 mol/L, collecting a eluent of the sodium chloride solution with the concentration of 0.5 mol/L, conducting concentration, conducting dialysis and desalting through a dialysis bag, and conductingfreeze-drying. The refined plant polysaccharide can promote the proliferation and migration of human skin fibroblast, has the effect of promoting skin regeneration, is free of obvious irritation to human skin and has the value of preparing the skin regeneration promoting cosmetics.

Description

technical field [0001] The invention belongs to the field of cosmetics and relates to the use of polysaccharides from natural sources in cosmetics, in particular to a refined plant polysaccharide, a preparation method and an application for preparing cosmetics. Background technique [0002] It is human nature to love beauty, but with age, people's skin repair ability and skin elasticity will decline. [0003] Human skin repair ability mainly depends on the proliferation speed and migration ability of human skin fibroblasts. As people age, the decline in proliferation speed and migration ability of skin fibroblasts is the direct cause of the decline in skin repair ability. [0004] The elasticity of human skin is mainly related to the content of collagen and elastin. Collagen and elastin are composed of collagen fibers and elastic fibers respectively. Collagen fibers mainly support volume, maintain moisture, and make the skin plump. Elastic fibers mainly enable the skin to s...
