Embodiment 1
[0022] Step 1: Take 50kg of bovine brain marrow, 10kg of bone marrow, and 50kg of spinal cord, wash them, dry them, cut them into pieces and mix them;
[0023] Step 2: For example, add 30kg of acetone to the mixture, extract in a water bath, filter the crude extract, slowly add 1% calcium chloride dropwise after activated carbon decolorization until no precipitation occurs, centrifuge at 10000r / min for 20min, take the precipitate, and add dropwise 0.01mol / L hydrogen chloride until the precipitate is completely dissolved, put it into a dialysis bag, dialyze for 36h, freeze-dry after rotary evaporation, and obtain the crude extract;
[0024] Step 3: Take the crude extract and extract by soaking in absolute ethanol at room temperature for 4 times, each time for 24 hours, the amount of ethanol is 5 times the volume of the crude extraction, filter with suction, combine, concentrate under reduced pressure to 120mL, shake well and take 100mL of the liquid medicine Use petroleum ether...
Embodiment 2
[0028] Step 1: Take fresh bovine brain marrow: 25kg, bone marrow: 5kg, spinal cord: 25kg, wash and process, cut into pieces and mix after drying;
[0029] Step 2: Add 15kg of acetone to the mixture, extract in a water bath, filter the crude extract, slowly add 1% calcium chloride dropwise after decolorization with activated carbon until no precipitation occurs, centrifuge at 10000r / min for 10min, take the precipitate, and add 0.01 mol / L hydrogen chloride until the precipitate is completely dissolved, put it into a dialysis bag, dialyze for 48 hours, freeze-dry after rotary evaporation, and obtain a crude extract;
[0030] Step 3: Take the crude extract and extract by soaking in absolute ethanol at room temperature for 4 times, each time for 24 hours, the amount of ethanol is 8 times the volume of the crude extraction, filter with suction, combine, concentrate under reduced pressure to 120mL, shake well and take 100mL of liquid medicine Use petroleum ether as the extraction age...
