Embodiment 1
[0034] a. Take 100g of fresh bone marrow, wash 3 times, remove broken bones and blood stains, pre-cool, chop into small pieces, add liquid nitrogen to crush at a weight ratio of 1:5, and crush 3-4 times repeatedly to obtain crushed bone marrow powder , Keep in low temperature refrigerator for later use;
[0035] b. Add distilled water with a weight ratio of 1:10 to the bone marrow sample that has been pulverized in step a, and set it on a magnetic stirrer for 2 hours at a temperature of 30°C. Extract twice at a time, filter under reduced pressure, combine the extracts, and separate impurities And get the extract for use;
[0036] c. Put the extract obtained in step b at 4°C overnight to separate the oil and water layers, take out the upper oil layer, place the lower extract layer in a separatory funnel, add petroleum ether according to the volume ratio of material to liquid of 1:5, and shake it constantly Carry out degreasing, stand for 3 hours until no oily matter is seen in the ...
