Embodiment 1
[0058] Hydrogel Formulation
[0059] Preparation method: add sodium hyaluronate to about 1 / 2 water, soak for 24 hours, fully dissolve, and obtain sodium hyaluronate gel. Add the remaining about 1 / 2 water to sodium hydroxide to make about 5wt% sodium hydroxide solution, mix sodium polyacrylate and carbomer 940 evenly, then add it to the sodium hydroxide solution, and swell overnight to obtain carbomer gel glue. Mix the dissolved sodium hyaluronate solution with the carbomer gel, add glycerin, stir well, and vacuum defoam to obtain a hydrogel.
[0060] Preparation of hydrogel A1: Weigh the following ingredients, 15 grams of sodium hyaluronate, 2.5 grams of sodium polyacrylate, 3 grams of carbomer, 13 grams of glycerin, and 58 grams of water. Prepare the hydrogel according to the above hydrogel preparation method.
[0061] Preparation of hydrogel A2: Weigh the following ingredients, 15 grams of sodium hyaluronate, 2 grams of sodium polyacrylate, 3.5 grams of carbomer, 12.5 gr...
Embodiment 2
[0072] Preparation of Polygonatum by Steaming and Sunning
[0073] The specific processing method of steamed and sun-dried Polygonatum is as follows: take fresh Polygonatum, wash, remove beards, and air-dry or air-dry. Slice Polygonatum, thickness 2-4mm. Put it in a steamer and steam for 4 hours, then turn off the heat and simmer for 2 hours, then take it out and dry it at 60°C to obtain the steamed and sun-dried Polygonatum.
[0074] Polysaccharide Extraction from Polygonatum Polygonatum
[0075] Take 100 grams of steamed and sun-dried Polygonatum, add 10 times the amount of water and decoct twice for 30 minutes each time, combine the extracts, concentrate to 100 ml, add absolute ethanol for precipitation to make the alcohol content reach 60v%, filter to remove the precipitate . Continue to add absolute ethanol to the filtrate to make the alcohol content of the filtrate reach 80v%, collect the precipitate, and dry to obtain Polygonatum polysaccharide N1 (60-80v% ethano...
