Embodiment 1
[0016] (a) 10g Angelica sinensis and 10g dried ginger are added to 50% ethanol of 5 times of their total weight, and they are refluxed and extracted once for 2 hours, then the extract is recovered ethanol and concentrated to a relative density of 1.15~1.20 (80°C), After cooling, extract 1 time with ethyl acetate for extracting 1 times the amount of the concentrated solution gross weight, and the extraction solution reclaims ethyl acetate and concentrates to obtain extract 1;
[0017] (b) 80g Yuanhu was added into 50% ethanol of 5 times its weight and extracted for 1 time for 2 hours, then the extract was recovered with ethanol and concentrated to a relative density of 1.05-1.10 (80° C.), and the extraction concentrate was The pH value is adjusted to 9, and is extracted once with ethyl acetate that is 1 times the total weight of the extraction concentrate, and the extract reclaims ethyl acetate and concentrates to obtain extract 2;
[0018] (c) the polyethylene glycol-6000 that...
Embodiment 2
[0020] (a) 30g Angelica sinensis and 20g dried ginger are added to 70% ethanol of 8 times of their total weight and extracted for 2 times, the 1st time is extracted with 4 times of ethanol for 2 hours, and the 2nd time is extracted with 4 times of ethanol Extract with ethanol for 1 hour, then combine the extracts to recover ethanol and concentrate to a relative density of 1.15 to 1.20 (80°C), and after cooling, extract twice with n-butanol that is 1.5 times the total weight of the extracted concentrate. The first time is 1 times the amount, the 2nd time is 0.5 times the amount, and after the extracts are combined, n-butanol is recovered and concentrated to obtain the extract 1;
[0021] (b) 50g Yuanhu is added to 70% ethanol of 8 times its weight and extracted twice, the first time is extracted with 4 times the amount of ethanol for 2 hours, and the second time is extracted with 4 times the amount of ethanol for 1 hour, Then the extracts were combined to recover ethanol and co...
Embodiment 3
[0024] (a) 50g Angelica sinensis and 30g dried ginger are added to 85% ethanol of 10 times of their total weight for reflux extraction 3 times, the 1st time is extracted with 4 times of ethanol for 3 hours, and the 2nd time is extracted with 3 times of ethanol Ethanol extraction for 2 hours, the third extraction with 3 times the amount of ethanol for 1 hour, then the extracts were combined to recover ethanol and concentrated to a relative density of 1.15 to 1.20 (80 ° C), after cooling, it was used to extract 2.0 times the total weight of the concentrate The amount of butanone was extracted 3 times, the 1st time was 1 times the amount, the 2nd time and the 3rd time were both 0.5 times the amount, the extracts were combined and recovered butanone and concentrated to obtain extract 1;
[0025] (b) 20g Yuanhu is added into 85% ethanol of 10 times its weight and extracted for 3 times, the first time is extracted with 4 times of ethanol for 3 hours, and the second time is extracted ...
