The vitamin B1, B2, B6 and B12 contents in the pyloric appendages of several fishes were determined. The results obtained were summarized in Tables 1, 2, 5 and 6.
Of the amount of various vitamins contained in the pyloric appendages, B1 ranged from 80 to 400γ%, B2 from 170 to 840γ%, B6 from 1 to 4.9γ/g and B12 was equivalent to 1.2 and 2.1γ%.
However, among the same species of fish the vitamin B1 and B2 contents of the pyloric appendages does not change markedly. It appears that the pyloric appendages keep these vitamins in the constant amount needed for physiological function.
