Abstract

The invention discloses a production method of natural tremella polysaccharide, wherein the production method comprises the following steps: selecting dry pest-free and non-toxic tremella, and crushing for standby application; adding distilled water into a container containing the dry tremella, extracting, adjusting the pH to 9.0 or more with an alkali, and extracting for 24-28 h at room temperature; after completion of the extraction, adding cation resin, washing, and adjusting the pH to 7.0 or less; next, intercepting high-molecular-weight impurities with an ultrafiltration film; concentrating the filtrate with a single-effect concentrator to the proportion of 1:3-1:5; carrying out alcohol precipitation of the concentrated liquid with ethyl alcohol, stirring for 1-2 h, and allowing to stand for 12-18 h; then using a plate type filter press, and collecting a white solid, namely the tremella polysaccharide. The invention also discloses an application of the natural tremella polysaccharide in production of cosmetic raw materials. The natural tremella polysaccharide has excellent antioxidant property; compared with ordinary tremella polysaccharide, although the final concentrations of the tremella polysaccharides are the same, the natural tremella polysaccharide has more excellent antioxidant property and has the effect of preventing skin aging.

Description

technical field [0001] The invention relates to a production method of natural tremella polysaccharide, and also relates to an application of natural tremella polysaccharide in the production of cosmetic raw materials. Background technique [0002] Tremella is the fruiting body of the fungus Tremella fungus of the phylum Basidiomycota, and Tremella is composed of more than 10 thin and wrinkled flat petals. Tremella fruiting body is pure white to milky white, generally in the shape of a chrysanthemum or a cockscomb, with a diameter of 5 to 10 cm, soft and white, translucent, elastic, composed of several pieces, shaped like a chrysanthemum, peony or hydrangea, with a diameter of 3 to 15 cm cm. Shrink after drying, the horny is hard and brittle, white or beige. Hymenium gives birth to petal surface. The burden is nearly spherical or nearly oval, separated vertically, and born on the rotting wood of broad-leaved trees in summer and autumn. [0003] Wild white fungus is rare,...
