【摘要】 本文报道由猪全血或牛全血中的血红蛋白制得氯化血红素、原卟啉,再由原卟啉直接制得乙酰血卟啉的方法。本法改革了制备工艺,减少了实验步骤,操作简便,乙酰血卟啉的产率较高,降低了成本。

【Abstract】 A preparation method of acetyl-hematoporphyrin is presented.Defibratedwhole blood of pig or cattle was heatedwith glacial acetic acid to get haemin.Itwas found that haemin.whether it wasproduced from pig blood or bovine blood,had a similar crystal shape and crystal size.By refluxing the mixture of haemin,formicacid solution and iron powder,protopor-phyrin was obtained and then acctylizedby heating the mixture of protoporphyrinand acids.The procedure proposed herehas some advantages over Lipson’s meth-od.It does not require corrosive hydro-bromic acid.The experimental proceduresare simpler,and the yield is a bit higher.The spectra of hematoporphyrin and itsacetyl derivative are shown here.
