抄録

The edible blue-green alga (cyanobacterium), Suizenji-nori, contained 143.8±22.4 μg of vitamin B₁₂ 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 B₁₂, but to those of pseudovitamin B₁₂ which is inactive for humans.
