The amounts of B vitamins in the urine of rats fed DAB, AB and rice only were determined.
The concentration of thiamine, niacin, and pyridoxic acid in the urine showed no remarkable changes by the ingestion of azo dyes. Riboflavin, however, was amazingly increased in the urine of rats fed DAB. AB had also some flavin ejection effect, but this effect was weaker than DAB. The amount of riboflavin in the urine of guinea pig, which resists tumor induction by azo dyes was not affected by DAB feeding.
