| titleOfInvention | A kind of preparation method of sea buckthorn peel polysaccharide copper |
| abstract | The invention discloses a preparation method of sea buckthorn pericarp polysaccharide copper, comprising: step 1: adding the dried sea buckthorn pericarp to disodium hydrogen phosphate-citric acid buffer solution, adding papain, taking a water bath and then suction filtration to obtain an extract; Step 2: Weigh a certain quality of sea buckthorn peel polysaccharide, add sodium citrate and water, heat in a water bath at 55 to 65 ° C and keep stirring; adjust the pH value to alkaline with sodium hydroxide solution, slowly add sulfuric acid dropwise Copper, stop dripping copper sulfate immediately when insoluble matter appears, continue to heat and stir in a water bath for 0.8 to 1.2 hours, stop stirring, and collect the centrifuge; add 95% ethanol to the centrifuge to make the ethanol concentration After 12 to 18 hours in an environment of 3 to 5° C., the precipitate is collected by centrifugation to obtain a seabuckthorn pericarp polysaccharide-copper complex. The invention extracts polysaccharide from sea buckthorn peel, and successfully complexes the obtained polysaccharide with copper sulfate to prepare a sea buckthorn peel polysaccharide-copper complex, which provides a theoretical basis for promoting the development and utilization of sea buckthorn resources. |
