Embodiment 1
[0019] Grind the original medicinal material of turmeric, weigh 1 kg quantitatively, put it in a 20-liter extraction tank, add 10 liters of 95% ethanol to soak for 1 day, filter, save the filtrate for later use, add 10 liters of 95% ethanol to the filter residue and soak for 1 day, filter , the filtrate was combined with the first time, and the filter residue was discarded. The extract was concentrated to 150 ml by rotary evaporation to obtain the alcohol-extracted fraction of curcuma.
[0020] Load 10 L of processed Rohm and Haas XAD-4 macroporous resin into the macroporous resin chromatography system, and dry-load the curcumin alcohol extraction fraction on the macroporous resin chromatography column. First use 4 times column volume 40L 50% ethanol to elute the column body, discard the eluate, then use 4 times column volume 40L 80% ethanol to elute, save the eluate, and concentrate to a solid content of 0.3 g / ml, pass 0.22 micron filter membrane, obtains 50 milliliters of t...
Embodiment 2
[0031] Grind the original turmeric medicinal material, weigh 0.5 kg quantitatively, put it in a 10-liter extraction tank, add 6 liters of 70% ethanol to soak for 2 days, filter, save the filtrate for later use, add 6 liters of 70% ethanol to the filter residue and soak for 1 day, filter , the filtrate was combined with the first time, and the filter residue was discarded. The extract was concentrated to 70 ml by rotary evaporation to obtain the alcohol-extracted fraction of curcuma.
[0032] Put 5 L of processed Rohm and Haas XAD-4 macroporous resin into the macroporous resin chromatography system, and dry-load the curcumin alcohol extraction fraction on the macroporous resin chromatography column. First, the column was eluted with 6 times column volume of 30L 40% ethanol, and the eluate was discarded, then eluted with 6 times column volume of 30L 85% ethanol, and the eluate was stored and concentrated to a solid content of 0.2 g / ml. Cross 0.22 micron filter membrane, obtain ...
Embodiment 3
[0035] Grind the original medicinal material of turmeric, weigh 5 kg quantitatively, put it in a 100-liter extraction tank, add 60 liters of 80% ethanol to soak for 2 days, filter, save the filtrate for later use, add 60 liters of 80% ethanol to the filter residue and soak for 2 days, filter , the filtrate was combined with the first time, and the filter residue was discarded. The extract was concentrated by rotary evaporation to 700 ml to obtain the curcumin alcohol-extracted fraction.
[0036] Load 50 L of processed Rohm and Haas XAD-4 macroporous resin into the macroporous resin chromatography system, and dry-load the curcumin alcohol extraction fraction on the macroporous resin chromatography column. First use 3 times the column volume of 150L 60% ethanol to elute the column body, discard the eluate, and then use 3 times the column volume for 150L 95% ethanol to elute, save the eluate, and concentrate it to a solid content of 0.5 g / ml. 0.45 micron filter membrane, obtains...
