Embodiment 1
[0044] Using method A, the root raw material of coriander root was soaked in 5 times the volume of 90% ethanol for 8 hours, then refluxed at 50°C for 2 hours, and the extraction was repeated 4 times. Combine the extracts and filter. Concentrate the filtrate under reduced pressure at 50°C into a non-alcoholic extract. Add a small amount of water to dissolve the concentrated extract (volume ratio 1:1.5). Use AB-8 macroporous adsorption resin to absorb the solution, first wash away the more polar impurities with 3 times the column volume of water, and then elute with 5 times the column volume of 30% ethanol at a flow rate of 0.5ml / min , collect the eluent, concentrate and dry, the organic acid yield of Coriander root is 0.51%, and its purity is 43%.
Embodiment 2
[0046] Using method A, the root raw material of coriander root was soaked in 10 times the volume of 50% ethanol for 10 hours, then refluxed at 60°C for 0.5 hours, and the extraction was repeated 4 times. Combine the extracts and filter. Concentrate the filtrate under reduced pressure at 60°C into a non-alcoholic extract. Add a small amount of water to dissolve the concentrated extract (volume ratio 1:1.5). Utilize HPD100 type macroporous adsorption resin to absorb the solution, first wash away the more polar impurities with 2 times column volume of water, then elute with 3 times column volume of 95% ethanol at a flow rate of 0.5ml / min, collect The eluate was concentrated and dried, and the yield of coriander root organic acid was 1.61%, and its purity was 71%.
Embodiment 3
[0048]Using method A, the raw material of coriander root was soaked in 15 times the volume of 50% ethanol, soaked for 14 hours, extracted under reflux at 70°C for 2 hours, and the extraction was repeated once. Combine the extracts and filter. Concentrate the filtrate under reduced pressure at 70°C into an alcohol-free extract. Add a small amount of water to dissolve the concentrated extract (volume ratio 1:2). Utilize the HPD400 type macroporous adsorption resin to absorb the solution, first wash away the more polar impurities with water of 1 times the column volume, and then elute with 50% ethanol of 5 times the column volume at a flow rate of 2ml / min, collect and wash Deliquoring, concentrating and drying, the yield of coriander root organic acid is 0.79%, and its purity is 60%.
