Embodiment 1
[0027] Formulated Rosa Nutrients
[0028] Get the fruit or dried fruit of Rosa roxburghii, and get its pulp, peel and seeds respectively. Roughly pulverize the pulp of the rose fruit, soak it with 75% ethanol for 10 hours, then centrifuge to remove the residue, recover the ethanol from the extract, and obtain the alcohol extract of the rose fruit pulp. Separately take the pulp of Rosa roxburghii, coarsely crush the pulp of Rosa roxburghii, extract with hot water at 80° C. for 8 hours, and then filter to obtain the filtrate aqueous extract of Rosa roxburghii pulp. Grinding the peel of the rose fruit, soaking it with 85% acetone for 12 hours, then centrifuging to remove the residue, recovering the acetone from the extract to obtain the peel pigment of the rose fruit. Wash the seeds of Rosa rosea, dry them, grind them, then extract the seed powder with anhydrous ether for 20 hours, recover and remove the ether, add anhydrous MgSO 4 , place and filter to obtain the rose fruit se...
Embodiment 2
[0031] Formulated Rosa Nutritious Drink
[0032] Get the fruit or dry fruit of Rosa roxburghii, and get its pulp, pericarp and fruit stone (seed) respectively. Coarsely pulverize the pulp of Rosa roxburghii, reflux and extract with 65% ethanol for 1.5 hours, then centrifuge to remove the residue, collect the extract into ethanol, and obtain the alcoholic extract of Rosa rosea pulp. Separately take the pulp of Rosa roxburghii, coarsely crush the pulp of Rosa roxburghii, reflux extract in boiling water for 1.5 hours, and then filter to obtain the filtrate aqueous extract of Rosa roxburghii pulp. Grinding the peel of the rose fruit, soaking it with 70% acetone for 8 hours, then centrifuging to remove the residue, recovering the acetone from the extract to obtain the peel pigment of the rose fruit. Wash the thorn rose seeds, dry, grind, and then extract the seed powder with anhydrous ether for 24 hours, recover and remove the ether, add anhydrous MgSO 4 , place and filter to obt...

[0036] Comparison of Extraction Methods of Peel Pigment of Rosa roxburghii
[0037] Take the fruit or dried fruit of Rosa roxburghii, take its peel, and grind it into a homogenous slurry. Extract with water, methanol, ethanol, acetone, and petroleum ether for 24 hours, and then centrifuge to remove the residue to obtain various extracts.
[0038] Use distilled water, methanol, ethanol, acetone, and petroleum ether as blank controls respectively. At 28°C, use a spectrophotometer with an optical path of 1 cm to measure the absorbance of each extract at a wavelength of 360-480 nm. The results are shown in Table 1 below.
[0039] Table 1 Absorbance of various extracts under different wavelength conditions
[0040] wavelength
[0041] The results in Table 1 show that the pericarp pigment of Rosa rosea is easily soluble in strong polar solvents such as water, methanol, ethanol, acetone, etc., but insoluble in non-polar solvents such as petroleum ether. The extraction eff...
