Embodiment 1
[0032] The preparation of embodiment 1 Huobahua extract
[0033] Slice the Huoba flower root medicinal material, add water and decoct 2-5 times, combine the filtrate, heat and concentrate to a clear paste with a density of 1.05-1.07, add ethanol to the clear paste, adjust the ethanol concentration to 50-80%, let stand, and precipitate Filtrate, recover under reduced pressure at a temperature of 40-60°C, recover ethanol until it has no alcohol smell, the density of the thick paste is 1.30-1.35, and obtain the Huobahua root extract.
[0034] Take any one or more of the torch flower stems, branches, roots, root bark and peeled root core, slice them, and obtain the corresponding torch flower extract according to the above method.
Embodiment 2
[0035] The preparation of the hydrogel of embodiment 2 sustained-release torch flower extract
[0036] Dissolve chitosan in vinyl acetate solution at 25-35°C, stir to dissolve, add 1.5% glutaraldehyde in vinyl acetate solution, and react with magnetic stirring for 36 hours at 50°C to obtain transparent chitosan hydrogel ball; the molar ratio of chitosan to vinyl acetate is 1:15. Then in 10 grams of transparent chitosan hydrogel microspheres, add 1 gram of torch flower extract thick paste with a relative density of 1.30-1.35, shake on a shaker, add 5 grams of sodium chloride and 8 grams of absolute ethanol, and obtain slow A hydrogel releasing torch flower extract.
[0037] The hydrogel of the sustained-release torch flower extract obtained by the method uses vinyl acetate as a monomer to obtain a nanocomposite gel through in-situ free radical polymerization. The method has a simple process, not only effectively removes the clay residue in the polymer, but also greatly improv...
Embodiment 3
[0038] The preparation of the hydrogel of embodiment 3 sustained-release torch flower extract
[0039]Dissolve chitosan in vinyl acetate solution at 25-35°C, stir to dissolve, add 3.5% glutaraldehyde in vinyl acetate solution, and react with magnetic stirring for 50 hours at 70°C to obtain transparent chitosan hydrogel ball; the molar ratio of chitosan to vinyl acetate is 1:30. Then in 15 grams of transparent chitosan hydrogel microspheres, add 1 gram of the thick paste of the torch flower extract with a relative density of 1.30-1.35, shake on a shaker, add 10 grams of sodium chloride and 5 grams of absolute ethanol, and obtain slow A hydrogel releasing torch flower extract.
