Abstract

The edible blue-green alga (cyanobacterium), Suizenji-nori, contained 143.8+/-22.4 microg of vitamin B(12) per 100 g dry weight of the alga (mean+/-SE, n=4). A corrinoid compound was purified from the dried Suizenji-nori, and partially characterized. The silica gel 60 TLC and reversed-phase HPLC patterns of the purified corrinoid compound were not identical to those of true vitamin B(12), but to those of pseudovitamin B(12) which is inactive for humans.

摘要

可食用的蓝绿藻（蓝细菌）水前寺紫菜，每100克干重的藻类中含有143.8±22.4微克维生素B12（平均值±标准误，n = 4）。从干燥的水前寺紫菜中纯化出一种类咕啉化合物，并对其进行了部分表征。纯化的类咕啉化合物的硅胶60薄层层析和反相高效液相色谱图谱与真正的维生素B12不同，但与对人类无活性的假维生素B12相同。
