A kind of extraction method of high-purity low-molecular-weight Astragalus polysaccharide, product and application thereof |
| abstract |
The invention discloses an extraction method of high-purity and low-molecular-weight astragalus polysaccharide, its product and application. The extraction method comprises the following steps: after astragalus medicinal materials are sequentially subjected to low-temperature freeze-drying, pulverization and degreasing treatment, powdered astragalus is obtained; Streptococcus lactis FGM strain fermented and extracted powdered astragalus to obtain fermented astragalus powder; the fermented astragalus powder was subjected to multiple alcohol adjustment treatments, and the white precipitate after alcohol precipitation was subjected to vacuum drying treatment to obtain astragalus polysaccharide; the obtained astragalus polysaccharide was obtained; The astragalus polysaccharide is purified by deproteinization, depigmentation and dialysis successively to obtain the purified low molecular weight astragalus polysaccharide. Applying low molecular weight astragalus polysaccharides to cosmetic products for sun protection and/or after-sun repair. The astragalus polysaccharide extracted by the invention has the characteristics of small molecular weight, improved purity and improved effect stability. |
