Embodiment 1

[0042] Embodiment 1: the preparation method of white and water-soluble polysaccharide

[0043] Crush 100kg of dry white powder, add 1000L of amylase aqueous solution to make the final concentration of amylase above 2U, heat it at 40°C for 4 hours to obtain a hydrolysis mixture; heat the hydrolysis mixture to 60-80°C for reflux extraction for 140min, Add 2 times of petroleum ether directly to the extract, stir for 20 minutes, let stand for 1 to 3 hours to remove the upper layer solution containing petroleum ether, and obtain a lower layer solution that does not contain petroleum ether, and then centrifuge at 5000 to 8000rpm for 10 to 30 minutes to obtain the above Supernatant and precipitation I: Concentrate the supernatant under reduced pressure at 50-60°C to 1 / 15 of the original volume, then add 95% ethanol to a final concentration of more than 65%, alcohol precipitation for 15 hours, and conduct a 0.22μm ceramic membrane Filtrate once to obtain 43.8 kg of filtrate II and fil...

Embodiment 2

[0048] Embodiment 2: the preparation method of white and skin care products

[0049] Get 60 grams of lactic acid and dissolve it in water, then add 100 grams of chitosan (the degree of deacetylation of the purchased chitosan is 80-90%, the viscosity is 600-2000mPa·s, and the viscosity-average molecular weight reaches 3×10 6above), then add 700 grams of white and water-soluble polysaccharides obtained in Example 1 to the resulting solution, add 400 grams of distilled water, freeze to dry after mixing, and obtain white and skin care products.

Embodiment 3

[0050] Embodiment 3: water retention experiment of white and skin care products

[0051] Name Take 10g white and skin care products, starch, and bovine serum albumin dry samples and place them on a watch glass, add 30mL deionized water (compared to tap water), stir evenly at room temperature and let it stand, measure the surface at room temperature at different times See Table 1 for the changes in the weight of the substances on the dish.

Abstract

The invention relates to a rhizoma bletillae skin care product.A method for preparing the rhizoma bletillae skin care product includes thermally extracting dried rhizoma bletillae by the aid of distilled water, adding neutral protease into extract of the dried rhizoma bletillae, hydrolyzing proteins by the aid of the neutral protease, filtering the extract and concentrating the extract under reduced pressures; adsorbing the extract by the aid of columns to obtain eluent, concentrating the eluent and concentrating the eluent under reduced pressures to obtain pure rhizoma bletillae water-soluble polysaccharide products with the polysaccharide contents higher than 99%; adding rhizoma bletillae water-soluble polysaccharides, chitosan and lactic acid into water, mixing the rhizoma bletillae water-soluble polysaccharides, the chitosan, the lactic acid and the water with one another to obtain mixtures and freezing the mixtures until the mixtures are dried.The mixtures can be applied to healthcare products or medicines.

Description

technical field [0001] The invention belongs to the technical field of application of natural medicines, relates to a white and water-soluble polysaccharide product, and more specifically relates to a method for extracting white and water-soluble polysaccharides from white and its application. Background technique [0002] Bletilla striata, also known as Bletilla striata, is a perennial herb belonging to the family Orchidaceae, with a plant height of 18-60cm. Baiji is mainly distributed in East Asia, and sporadically distributed in Shaanxi, Gansu, Jiangsu, Anhui, Zhejiang, Jiangxi, Fujian, Hubei, Hunan, Guangdong, Guangxi, Sichuan, Chongqing, Yunnan and Guizhou provinces (cities) in China. It usually grows in evergreen broad-leaved forest or coniferous forest at an altitude of 100-3200m, and is scattered in roadside grass and rock crevices. The underground tubers of Baiji are thick, fleshy, and sticky, usually 3 pieces (5 or 1 for some species), which are oblate spherical o...
