Embodiment 1
[0101] Embodiment 1: the preparation of pharmaceutical composition of the present invention
[0102] Take notoginseng and grind it into 1000g of coarse powder, add 8000ml of 60% ethanol to extract for 7 hours, collect the extract, filter, take the filtrate to recover the ethanol until it has no alcohol smell, add water to make a solution containing 0.5g of crude drug per 1ml, and use a macroporous resin column (Class D macroporous resin, resin volume 3000ml, resin bed height to diameter ratio is about 8) and alumina adsorption, gradient elution with different concentrations of ethanol, the ethanol concentration is adjusted from 5% to 95% within 6 hours , flow rate 4.5BV / h, discard the eluate containing ethanol concentration other than 30% to 70%, collect the eluate containing ethanol concentration above 30% to below 70%, recover the solvent under reduced pressure below 65°C and concentrate To a clear paste with a relative density of 1.13 (60°C) to obtain the active ingredient ...
Embodiment 2
[0104] Embodiment 2: the preparation of pharmaceutical composition of the present invention
[0105]Take notoginseng and grind it into 1000g of coarse powder, add 10000ml of 50% ethanol to extract for 6 hours, collect the extract, filter, take the filtrate to recover the ethanol until it has no alcohol smell, add water to make a solution containing 0.4g of crude drug per 1ml, and use a macroporous resin column (Class D macroporous resin, resin volume 3000ml, resin bed height to diameter ratio is about 8) and alumina adsorption, carry out gradient elution with different concentrations of ethanol (the ethanol concentration is adjusted from 5% to 95% within 5.5 hours ), the flow rate is 5.0BV / h, discard the eluate containing ethanol concentration other than 30% to 70%, collect the eluate containing ethanol concentration above 30% to below 70%, recover the solvent under reduced pressure below 65°C and Concentrate to a clear paste with a relative density of 1.15 (60°C), dry to obta...
