Embodiment 1
[0014] Take 10kg of ginseng and grind it, add 5 times the amount of 70% ethanol solution, reflux extraction 3 times, combine the extracts to shrink to no alcohol, add to AB-8 macroporous resin for adsorption, first elute with 8 times the column volume of 30% ethanol, and then Elute with 7 times the column volume of 75% ethanol solution, collect the eluent, concentrate under reduced pressure, add an equal volume of benzene solution to the concentrated solution and stir thoroughly, collect the benzene solution layer and concentrate it to a small volume and place it for crystallization. The obtained crystals were dissolved in 10 times the amount of 80% methanol, added activated carbon to decolorize, the filtrate was concentrated to an alcohol concentration of 30%, and then extracted twice with benzene solution, the extract was added to 1 / 3 ethanol solution and placed for recrystallization, and the crystallized product obtained 3.5 g of ginseng lactone , detected by HPLC, the conte...
Embodiment 2
[0016] Take 10kg of ginseng and grind it, add 10 times the amount of 30% ethanol solution, reflux extraction twice, combine the extracts to shrink to no alcohol, add to D101 macroporous resin for adsorption, first elute with 5 times the column volume of 20% ethanol, and then use 10 The column volume was eluted with 70% ethanol solution, the eluate was collected, concentrated under reduced pressure, an equal volume of benzene solution was added to the concentrated solution and stirred thoroughly, the collected benzene solution layer was concentrated to a small volume and left to crystallize. The obtained crystals were dissolved in 5 times the amount of 90% methanol, added activated carbon to decolorize, the filtrate was concentrated to an alcohol concentration of 50%, and then extracted twice with benzene solution, the extract was added to 1 / 10 ethanol solution and placed for recrystallization, and the crystallized product obtained 3.1 g of ginseng lactone , detected by HPL...
Embodiment 3
[0018] Take 10kg of ginseng and grind it, add 10 times the amount of 90% ethanol solution, reflux extraction twice, combine the extracts to shrink to no alcohol, add an appropriate amount of water solution, then add HZ816 macroporous resin for adsorption, first wash with 5 times the column volume of 50% ethanol Then eluted with 10 times the column volume of 75% ethanol solution, collected the eluate, concentrated under reduced pressure, added an equal volume of benzene solution to the concentrated solution and stirred thoroughly, collected the benzene solution layer and concentrated it to a small volume and placed it for crystallization. The obtained crystals were dissolved in 8 times the amount of 80% methanol, added activated carbon to decolorize, the filtrate was concentrated to an alcohol concentration of 40%, and then extracted twice with benzene solution, and the extract was added to 1 / 5 ethanol solution and left to recrystallize, and the crystals obtained 3.9 g of gi...
