胆红素是天然牛黄的主要成分,也是胆汁的主要色素之一,它可用于治多种疾病。原料易得,方法简单,成本低廉,价格昂贵,经济效益显著。近年来各地举办学习班如雨后春笋般涌现,新的工艺层出不穷。但最后都要用氯仿来溶解浓缩结晶,因此有必要对这都不可少的一步加以研究。我们用二氯甲烷代替氯仿取得了很好的效果,仅就此—步进行探讨。
Bilirubin is the main component of natural bezoar and is also one of the major pigments of bile, which can be used to treat various diseases. Easy to get raw materials, the method is simple, low cost, expensive, significant economic benefits. In recent years, various seminars have been held in various places, and new techniques are emerging one after another. However, in the end, chloroform is used to dissolve the concentrated crystals, so it is necessary to study this step indispensable. We used methylene chloride instead of chloroform achieved good results, only this step - by-step discussion.
