Embodiment 1
[0034] In this embodiment, a ginseng oral liquid for nourishing yin and tonifying yang, comprising the following components in parts by weight: 5-10 parts of total ginseng extract, 10-30 parts of rehmannia glutinosa extract, 10-30 parts of Polygonatum extract, Polygonum multiflorum 5-20 parts of extract, 5-20 parts of privet fruit extract, 5-20 parts of wolfberry fruit extract, 5-20 parts of Chinese yam extract, 30-80 parts of small molecule ginseng polypeptide-zinc chelate; 500 parts of ionized water;
[0035] Wherein the preparation method step of small molecule ginseng polypeptide-zinc chelate is as follows:
[0036] S1. Extraction of ginseng water-soluble protein:
[0037] Clean the fresh ginseng and cut it into small pieces, add a Tris-HCl buffer solution with a neutral pH value according to a certain mass volume ratio, stir and extract at a certain temperature after stirring evenly, and collect the extract; repeat the extraction once and The two extracts are combined, ...
Embodiment 2
[0043] The difference between this example and Example 1 is that the ginseng oral liquid for nourishing yin and nourishing yang in Example 2 includes the following components in parts by weight: 8 parts of total ginsenoside extract, 20 parts of Rehmannia glutinosa extract, 20 parts of Rhizoma Polygonatum extract 10 parts of Polygonum multiflorum extract, 10 parts of Ligustrum lucidum extract, 10 parts of Lycium barbarum extract, 10 parts of Chinese yam extract, 50 parts of small molecule ginseng polypeptide-zinc chelate; 500 parts of deionized water.
Embodiment 3
[0045] The difference between this embodiment and embodiment 1 is that the steps of the preparation method of embodiment 3 small molecule ginseng polypeptide-zinc chelate are as follows:
[0046] S1. Extraction of ginseng water-soluble protein:
[0047] Wash the fresh ginseng and cut it into small pieces, add 0.01mol / L Tris-HCl buffer solution with a neutral pH value according to the mass volume ratio of 1g:10-15mL, stir evenly, and extract with stirring at 4°C for 3- 6h, collect the extract; repeat the extraction once and combine the two extracts, filter and clarify the extract with a 0.22-0.45μm filter membrane, and then place it in an ultrafiltration membrane device with a molecular weight cut-off of 5-30KDa Perform ultrafiltration, and collect the ultrafiltration retention liquid, which is the crude extract of ginseng water-soluble protein that removes small molecular impurities;
[0048] S2. Enzymolysis of ginseng water-soluble protein to prepare ginseng polypeptide:
