Although, in previous paper, the auther reported that rat liver had an enzyme converting O-benzoylthiamine (OBT) to thiamine, it is now found to be corrected. In the present report, it was clarified that liver homogenates of rat had the enzyme capable of converting OBT to B_1-thiazolone as reported by Utsumi et al. On the other hand, enzymes in brain, heart, kidneys and blood convert OBT to thiamine.
