Embodiment 1
[0044] Preparation:
[0045] 1) Preparation of high-purity resveratrol: Dried peanut red coat and pulverized it, carried out supercritical carbon dioxide extraction on crushed peanut red coat, used absolute ethanol and propanol as entraining agents, peanut red coat, entrainer, The mass ratio of the circulating amount of carbon dioxide per hour is 1:0.1:20, the pressure of the extraction tank is 10Mpa, the temperature is 50°C, the pressure of the separation tank is 5Mpa, the temperature is 20°C, the extraction time is 3h, the extract is collected, concentrated, and the Put the concentrate on a macroporous resin adsorption column, elute with 30% ethanol, collect the eluate, concentrate and dry to obtain high-purity resveratrol with a purity of 95%;
[0046] 2) Spirulina is crushed, mixed evenly with high-purity resveratrol, and passed through a 50-mesh sieve to obtain a resveratrol-spirulina composition.
Embodiment 2
[0049] Preparation:
[0050] 1) Preparation of high-purity resveratrol: crush grape seed pomace, add 90% ethanol to reflux and extract for 3 times, the amount of ethanol added for the first time is 5 times that of grape seed pomace, reflux for 5 hours, and add The amount of ethanol is 6 times that of grape seed pomace, reflux for 2 hours, the amount of ethanol added for the third time is 1 times that of grape seed pomace, reflux for 3 hours, combine the reflux liquid, filter, and concentrate the filtrate until the temperature is 70 °C and the relative density is The thick paste of 1.30 was dried to obtain the grape seed pomace extract; the grape seed pomace extract was dissolved in 1% aqueous sodium bicarbonate solution, stirred for 50 min, and the precipitate was separated, washed with water until neutral, and then The precipitate was added to 10 times the amount of water, dissolved at 90°C, the aqueous solution was slowly cooled to 25°C, left to stand, the precipitate...
Embodiment 3
[0056] Preparation:
[0057] 1) Preparation of high-purity resveratrol: Dissolve 0.01mol of 3,5-dimethoxybenzaldehyde and 0.01mol of p-methoxyphenylacetonitrile in 10ml of ethanol, add 0.02mol of sodium metal, and heat at 75°C Reflux for 12 hours, cool, and precipitate crystals to obtain 3,4', 5-trimethoxystilbene nitrile. Dissolve 3,4', 5-trimethoxystilbene nitrile in ethylene glycol, add hydroxide Sodium 0.3mol, stir, react at 130°C, then add dilute hydrochloric acid to acidify, and hydrolyze to obtain 3,4', 5-trimethoxystilbene acid, under the catalysis of Cu, in quinoline at 200 decarboxylation reaction at ℃ to obtain trans-3,4',5-trimethoxystilbene, under the catalysis of boron tribromide, demethylation reaction at 30 ℃ to obtain resveratrol with a purity of 99% alcohol;
[0058] 2) Preparation of Astragalus extract: crush Scutellaria baicalensis, add water and decoct three times, the first water consumption is 10 times the weight of Astragalus, decocting for 3 h...
