Abstract
In the previous report1), the authors have studied on the crystallization of a certain organic base from dried cuttle fish meat (“Surume”) extractives and compared it with some authentic organic bases, but we have fallen into difficulties of its crystallization, and found no coincidence of it with those authentic samples.
For the purpose of further purification of an organic base found in the meat extractives, the organic base fraction obtained by treating with IR-120 and IRA-4002) was rechromatographed on Dowex-50 according to the method described by WALL8) (Figs. 1 and 2). The position of peak of the base was located at the position of cytosine, nicotinic acid, pyridoxine or p-amino-benzoic acid. The base was found to be precipitable with phosphotungstic acid (Figs. 3 and 4).
