Embodiment 1

[0017] Polygonatum and oyster mushrooms were mixed at a mass ratio of 1:1 (polygonatum and oyster mushrooms in total 100g) for rough extraction and concentrated to 50mL. At room temperature, 20mL of a two-phase aqueous system was prepared at a mass percentage of sodium carbonate and ethanol of 10%. The concentrated crude Add 5mL of the extract to the two-phase aqueous system, stir magnetically at a constant temperature (10°C, 300r / min) for 40min to enrich Polygonatum polysaccharide and Pleurotus ostreatus polysaccharide, let it stand for 80min, and centrifuge at 1500rpm for 30min to separate the enriched phase of the polysaccharide mixture , the polysaccharide solution extracted from the two-phase aqueous phase was placed in a 4°C refrigerator for a period of time, crystallized and precipitated most of the inorganic salts, and then dialyzed to obtain a mixed extract of polygonatum polysaccharide and oyster mushroom polysaccharide; take 10g of the extract, add flour, eggs, etc. t...

Embodiment 2

[0020] Polygonatum and Pyramid mushrooms were mixed at a mass ratio of 10:1 (Polygonatum and Pleurotus 100g in total) for rough extraction and concentrated to 50mL. At room temperature, 20mL of a two-phase system was prepared at a mass percentage of sodium carbonate and isopropanol of 30%. The concentrated Add 5mL of the crude extract to the two-phase system, stir magnetically at a constant temperature (35°C, 300r / min) for 30min to enrich Polygonatum Polysaccharides and Pleurotus polysaccharides, let it stand for 60min, and centrifuge at 1000rpm for 20min to separate the polysaccharide mixture rich in Phase collection, put the polysaccharide solution extracted from the two-phase aqueous phase in a refrigerator at 4 °C for a period of time, crystallize and precipitate most of the inorganic salts, and then dialyze to obtain a mixed extract of polygonatum polysaccharide and oyster mushroom polysaccharide; take 10g of the extract, add flour, eggs, etc. Make it into a paste; after w...

Embodiment 3

[0023] Mix Polygonatum and Pleurotus in a mass ratio of 4:1 (Polygonatum and Pleurotus 100g) for rough extraction and concentrate to 50mL. At room temperature, prepare 20mL of a two-phase system according to the mass percentage of ammonium sulfate and isopropanol at 30%. Add 5mL of the crude extract from the two-phase system to the two-phase system, stir magnetically at a constant temperature (50°C, 300r / min) for 60min to enrich Polygonatum polysaccharide and Pleurotus ostreatus polysaccharide, let it stand for 100min, and centrifuge at 2000rpm for 40min to separate the polysaccharide mixture rich in Phase collection, put the polysaccharide solution extracted from the two-phase aqueous phase in a refrigerator at 4 °C for a period of time, crystallize and precipitate most of the inorganic salts, and then dialyze to obtain a mixed extract of polygonatum polysaccharide and oyster mushroom polysaccharide; take 10g of the extract, add flour, eggs, etc. Make it into a paste; after wa...

Abstract

The invention provides a method for simultaneously extracting radix polygonati officinalis polysaccharide and oyster mushroom polysaccharide by an aqueous two-phase extraction technology at high yield. According to the method, radix polygonati officinalis and oyster mushrooms are used as raw materials to obtain mixed crude extraction liquid of the radix polygonati officinalis and the oyster mushrooms; the mixed crude extraction liquid is extracted and separated by a low-molecular alcohol / salt aqueous two-phase system; then, through separation and purification, extraction liquid of the radix polygonati officinalis polysaccharide and the oyster mushroom polysaccharide is obtained. When the mixed extraction liquid of the radix polygonati officinalis polysaccharide and the oyster mushroom polysaccharide is applied to a skin external agent, the skin care effects of beautifying the features and preserving moisture are achieved.

Description

technical field [0001] The invention belongs to the technical field of natural product extraction and cosmetics, and in particular relates to a method for synchronously extracting Polygonatum polysaccharides from Polygonatum polysaccharides and Pleurotus ostreatus. Background technique [0002] Pleurotus ostreatus, also known as Pleurotus otreatus, Pleurotus ostreatus, oyster mushroom, etc., belongs to Basidiomycotina, and is a fairly common gray edible mushroom. The content of Pleurotus polysaccharides in Pleurotus ostreatus is relatively high, and some extraction methods of Pleurotus ostreatus polysaccharides are also limitedly disclosed in the prior art (CN103202864A, 20130717; CN104342467A, 20150211; CN101492705A, 20090729; "Extraction of Pleurotus ostreatus polysaccharides and its antioxidant moisturizing Efficacy research", Dong Yinmao et al., "Fragrance, Fragrance and Cosmetics", Issue 4, August 2008). [0003] Polygonatum odoratum (polygonatum odoratum), a perennial...
