Studies were made on emigration of vitamin B_2 (free riboflavin, FMN and FAD) into saliva. Saliva was taken from the salivary fistula made artificially at the submaxillary and sublingual glands of a healthy dog. Subcutaneus, intramuscular or intravenous injection of 1-20mg of free riboflavin or intravenous administration of 1-20mg of FMN caused no change in salivary vitamin B_2 within 3 hours at least. However, a small amount of FMN was found in saliva when 4mg of the substance had been injected intravenously. Injection of 10-20mg of FMN caused a remarkable emigration of vitamin B_2 into saliva. The most distinct result was observed in the case of FAD administration. Namely, the vitamin proved to be emigrated into saliva even when only 1mg had been injected. Paper chromatographical studies showed that the vitamin appeared in saliva in the esterified forms.
