Is it true that Wang Yifa of Huangshan City, Anhui Province extracted heparin sodium from pig small intestine and lung? thank you
I happen to be engaged in this industry. I don't know about Wang Yifa in Huangshan City, but heparin sodium can be extracted from pig's small intestine, and there is also a small amount of heparin sodium in the lung, but it is not economical to extract it because the content in the lung is too small. The production and extraction of heparin sodium in the market are all extracted from pig small intestine, in which adsorption resin and auxiliary materials such as acid, alkali, salt and enzyme powder are used. At present, the domestic market price is around 20,000 yuan.
