Embodiment 1
[0034] In this embodiment, a ginseng oral liquid for invigorating qi and calming nerves comprises the following components in parts by weight: 5-10 parts of total ginseng extract, 10-30 parts of astragalus extract, 10-30 parts of Acanthopanax extract, Poria cocos 5-20 parts of extract, 5-20 parts of cypress kernel extract, 5-20 parts of wolfberry fruit extract, 5-20 parts of jujube seed extract, 30-80 parts of small molecule ginseng polypeptide-zinc chelate; deionized 500 parts of 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, and the extract...
Embodiment 2
[0043] The difference between this example and Example 1 is that the ginseng oral liquid for invigorating Qi and calming nerves in Example 2 includes the following components in parts by weight: 8 parts of total ginsenoside extract, 20 parts of Astragalus extract, 20 parts of Acanthopanax extract 15 parts of poria cocos extract, 15 parts of cypress seed extract, 15 parts of wolfberry fruit extract, 15 parts of jujube seed extract, 60 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:
