Embodiment 1
[0047] Preparation of Monomer Compounds
[0048] Get 300kg of the medicinal material Paleopsis cumulus, after decocting and ethanol precipitation to remove impurities, add milk of calcium oxide to make the flavonoids complex with it and precipitate 75kg, suspend the precipitate in ethanol (90%), adjust to Acidic pH = 4, so that the flavonoids are freely dissolved in ethanol, centrifuged to remove insoluble matter, then adjust the ethanol solution to neutral pH = 7, filter out the precipitate, recover the ethanol solution until it has no alcohol smell, and obtain a relative Pure total flavone extract (total flavone content is about 70%) 2100g. Add water to the total flavonoids extract to prepare a concentration of 10g of crude drug per ml, successively elute with distilled water, 30%, 60%, and 95% ethanol through the treated polyamide chromatography column, recover ethanol from each part, and treat with an organic solvent Repeated recrystallization obtained relatively high-pur...
Embodiment 2
[0050] Preparation of Monomer Compounds
[0051] Take 300kg of the medicinal material, Pasternia cumulus, decoct in water and alcohol to precipitate impurities, add calcium oxide milk to make the flavonoids complex with it and precipitate 90kg, suspend the precipitate in ethanol (90%), and adjust it to acidity pH = 4, so that the flavonoids can be freely dissolved in ethanol, centrifuged to remove insoluble matter, then adjust the ethanol solution to neutral pH = 7, filter out the precipitate, recover the ethanol solution until it has no alcohol smell, and obtain a comparative Pure total flavone extract (total flavonoid content is about 70%) 1830g. Add water to the total flavonoids extract to prepare a concentration of 10g of crude drug per ml, elute with 30%, 60%, and 95% ethanol successively through the treated macroporous resin column, recover ethanol from each part, and recrystallize repeatedly after being treated with an organic solvent , to obtain a relatively high puri...
