Studies were made on the effects of riboflavin derivatives upon the disorder of tryptophan metabolism caused by the liver injury. When tryptophan had been administered, the liver injured rats excreted a higher amount of xanthurenic acid, and a smaller amount of kynurenine and anthranilic acid than the normal rats. When riboflavin derivatives had been given with tryptophan, a more remarkable decrease of anthranilic acid and kynurenine and a slight increase of N-methylnicotinamide in the urine were observed, and FMN caused a remarkable decrease of xanthurenic acid excretion.
