Embodiment 1
[0168] The preparation method of Xanthophyllum flavonoids extract described in the present embodiment comprises the following steps:
[0169] Take 1.0 kg of decoction pieces of Xanthomonas xanthus, add 10 L of ethanol solution with a volume concentration of 50% and a pH value of 2.5, and extract 3 times under reflux, and extract for 1 hour each time, recover the solvent under reduced pressure to obtain a crude extract, add a certain volume of water to disperse Dissolve so that the volume ratio of the crude extract weight to the dispersed solution is 1:3.5, pass through 7.5L of S-8 macroporous adsorption resin, the adsorption flow rate is 2Bv / h, the resin column diameter-to-height ratio is 1:10, wash with water Remove 1.5 times the resin volume for impurity removal, the impurity removal flow rate is 2Bv / h, elute 8 times the resin volume with a volume concentration of 50% ethanol solution, the elution flow rate is 2Bv / h, collect the volume concentration 50% ethanol eluate, and re...
Embodiment 2
[0172] The preparation method of Xanthophyllum flavonoids extract described in the present embodiment comprises the following steps:
[0173] Take 0.5 kg of decoction pieces of Xanthomonas xanthus, add 15 L of ethanol solution with a volume concentration of 70% and a pH value of 10, perform ultrasonic extraction for 3 times, each time for 1.5 hours, and recover the solvent under reduced pressure to obtain a crude extract, add a certain volume of Disperse and dissolve in water so that the ratio of the weight of the crude extract to the volume of the solution after dispersion is 1:5, pass through 10L of D4020 macroporous adsorption resin, the adsorption flow rate is 2Bv / h, the ratio of diameter to height of the resin column is 1:6, and elute with water 2 times the resin volume for impurity removal, the impurity removal flow rate is 4Bv / h, 8 times the resin volume is eluted with a volume concentration of 50% ethanol, the elution flow rate is 1Bv / h, the volume concentration 50% eth...
Embodiment 3
[0176] The preparation method of Xanthophyllum flavonoids extract described in the present embodiment comprises the following steps:
[0177] Take 1.5 kg of decoction pieces of Xanthomonas xanthus medicinal material, add 6 L of ethanol solution with a volume concentration of 80% to reflux and extract twice, extract for 3 hours each time, recover the solvent under reduced pressure to obtain a crude extract, add a certain volume of water to disperse and dissolve, so that the The ratio of the weight of the crude extract to the volume of the solution after dispersion is 1:8, through 8L of HPD400 macroporous adsorption resin, the adsorption flow rate is 1Bv / h, the ratio of diameter to height of the resin column is 1:7, and water is eluted to remove impurities by 4 times the volume of the resin , the impurity removal flow rate is 6Bv / h, 7 times the resin volume is eluted with a volume concentration of 80% methanol solution, the elution flow rate is 9Bv / h, the volume concentration of ...
