Embodiment 1
[0035] Example 1: Preparation of Radix chinensis extract
[0036] (1) 26kg of Radix vulgaris, crushed, passed through a 30-mesh sieve, using supercritical carbon dioxide extraction technology, extraction temperature 45°C, extraction pressure 25MPa, extraction time 2h, extract volatile oil, and collect the volatile oil, that is, the extract of Radix Radix et al. A, after the extraction of supercritical carbon dioxide, the medicinal residues A of A.
[0037] (2) Using 80% ethanol as a solvent, the medicinal residue A obtained in step (1) was warmly soaked and extracted at 70 ° C, the extraction times were 2 times, the extraction time was 2 hours each time, and the amount of solvent each time was 2 hours. It is 12 times of the weight of Alpinia chinensis, filtered to obtain medicinal residues B and an extract, and the extract reclaims ethanol, concentrated, and dried to obtain Alpinia chinensis extract B;
[0038] (3) The medicinal residue B obtained in step (2) is extracted by ...
Embodiment 2
[0040] Example 2: Preparation of Radix chinensis extract
[0041] (1) 20kg of Radix vulgaris, crushed, passed through a 10-mesh sieve, using supercritical carbon dioxide extraction technology, extraction temperature 40-℃, extraction pressure 20MPa, extraction time 1h, extract volatile oil, and collect volatile oil, that is, the extraction of Radix Radix et Rhizoma Substance A, after the extraction of supercritical carbon dioxide, the medicinal residues A of A.
[0042] (2) Using 70% ethanol as a solvent, the medicinal residue A obtained in step (1) was warmly soaked and extracted at 50 ° C, the extraction times were 2 times, the extraction time was 1 hour each time, and the amount of solvent each time was 1 hour. It is 10 times of the weight of Fructus chinensis, filtered to obtain medicinal residues B and extract, the extracting solution reclaims ethanol, concentrated, and dried to obtain Fructus chinensis extract B;
[0043] (3) The medicinal residue B obtained in step (2) ...
Embodiment 3
[0045] Example 3: Preparation of Radix chinensis extract
[0046] (1) 19kg of Radix chinensis, crushed, passed through a 50-mesh sieve, using supercritical carbon dioxide extraction technology, extraction temperature 50°C, extraction pressure 30MPa, extraction time 2h, extract volatile oil, collect volatile oil, that is, Radix Radix et Rhizoma extract A, after the extraction of supercritical carbon dioxide, the medicinal residues A of A.
[0047] (2) Using 95% ethanol as a solvent, the medicinal residue A obtained in step (1) was warmly soaked and extracted at 80° C. The extraction times were 4 times, and the extraction time was 3 hours each time, and the amount of solvent each time was 3 hours. It is 15 times of the weight of Alpinia chinensis, filtered to obtain medicinal residues B and an extract, and the extract reclaims ethanol, concentrated, and dried to obtain Alpinia chinensis extract B;
[0048] (3) The medicinal residue B obtained in step (2) is extracted by adding ...
