Embodiment 1
[0119] Embodiment 1 Preparation of safflower yellow pigment
[0120] Take the dried safflower crude powder, and soak it with acid water with a pH of 3 for three times at 70°C, each time with 50 times the amount of acid water, for 1.5 hours each time. Combine the extracts, filter, collect the filtrate, let it cool, adjust the pH value to neutral, concentrate under reduced pressure to a relative density of 1.05-1.10, add ethanol until the alcohol concentration is 70%, refrigerate (below 10°C) for 24 hours, filter Had a good time. Dissolve the precipitate in water, add it to the processed macroporous adsorption resin HPD100 column chromatography (the ratio of medicinal material to resin is 1:10 (W / V)), first use deionized water at 1-2.5ml / cm 2 / min flow rate to elute two column bed volumes, and then use 60% ethanol at 1-2.5ml / cm 2 / min flow rate to elute five column bed volumes. The fraction eluted with 60% alcohol is concentrated under reduced pressure to a density of about 1...
Embodiment 2
[0129] Example 2 Preparation of total flavonoids from hawthorn leaves
[0130] Take hawthorn leaves, add 75% ethanol to reflux and extract three times, each time for 1.5 hours, combine the extracts, filter, and recover the ethanol from the filtrate under reduced pressure until it has no alcohol smell, add an equal amount of water to dilute, and degrease with 1 / 2 amount of petroleum ether Finally, discard the petroleum ether liquid, and then extract it with ethyl acetate, recover the ethyl acetate under reduced pressure and concentrate to dryness, add an appropriate amount of water to dissolve it, and add it to the treated polyamide column (particle size: 30-60 For this purpose, use 95% ethanol to wet-pack the column, first elute with 3 times column volume of 95% ethanol, then use 3 times column volume of water to elute until there is no alcohol smell, standby), first use 2 times column volume of water Elution, discard the washing liquid, then elute with 3 times column volume o...
