Examples
Embodiment 1
[0035] This example provides the extraction method and characterization of compounds 4-7 in the active ingredients.
[0036] The ethanol, ethyl acetate, petroleum ether and methanol used in this example are all commercially available products.
[0037]Take 100kg of Atractylodes atractylodis from Compositae, crush them, soak and extract with 15 times the volume of 70% ethanol aqueous solution, the extraction temperature is 50-100°C, the extraction time is 120min, and concentrate under reduced pressure until there is no solvent to obtain a concentrated solution A; Concentrate A is separated through a low-pressure D101 column (column diameter 28cm×height 162cm, column volume 100L), utilizes volume concentration to be 30%, 95% ethanol-water solution elution 4BV respectively, collects 95% part; After this part is concentrated (solid content about 3kg) separated by LX-20SS column (column diameter 20cm×height 78cm, column volume 25L), elute 3BV with ethanol-water solution with volume...
Embodiment 2
[0047] This example provides the extraction method and characterization of compounds 8-11 in the active ingredients.
[0048] The n-pentane, ethyl acetate, diethyl ether, ethanol and methanol used in this example are all commercially available products.
[0049] Cut 20kg of carrots into small pieces, chop them with a mixer, and then use 40L of n-pentane and 30L of ethyl acetate to extract 3 times at room temperature successively, collect the n-pentane extract and the ethyl acetate extract respectively, and reduce Concentrate under reduced pressure to remove the organic solvent to obtain 20 g of n-pentane extract (ie: component A) and 15 g of ethyl acetate extract (ie: component B) respectively. Component B was dissolved in 35 mL of a mixed solution of n-hexane and ethyl acetate, wherein the volume ratio of n-hexane and ethyl acetate was 95:5, and passed through a silica gel column (column diameter 6 cm × height 60 cm, column volume 1.7 L) ) separation and purification, using ...
Embodiment 3
[0057] This example provides the extraction method and characterization of compounds 12-14 in the active ingredients.
[0058] The ethanol, ethyl acetate, petroleum ether and methanol used in this example are all commercially available products.
[0059] Pulverize 100 kg of snow chrysanthemum medicinal material, soak and extract with 15 times the volume of ethanol aqueous solution with a volume concentration of 70% at room temperature, concentrate under reduced pressure to remove the organic solvent, and obtain a concentrate. The concentrate was extracted with 1 volume of ethyl acetate for three times, the ethyl acetate layers were combined, and concentrated under reduced pressure to remove the organic solvent to obtain ethyl acetate extract. The ethyl acetate extract was separated by ODS reverse-phase silica gel column chromatography (column diameter 6cm×height 60cm, column volume 1.7L), and methanol-water solution was used as the mobile phase to carry out gradient elution ac...
