Tyrosol is considered a potential antioxidant; however, little is known regarding the pharmacokinetics of its metabolites. To study the pharmacokinetics of tyrosol-derived metabolites after oral administration of a single dose of tyrosol, we attempted to identify tyrosol metabolites in rat plasma by using ultra-performance liquid chromatography and quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS). Two tyrosol metabolites (M1 and M2) were detected in the plasma. M1 was identified as tyrosol-4-sulfate (T4S) with an [M − H] ion at m/z 217. While M2 showed an [M − H] ion at m/z 151.0, its metabolite was not identified. Pharmacokinetic analysis of T4S and M2 showed rapid uptake after oral administration of tyrosol within 1 h. The metabolites were rapidly distributed in most organs and tissues and eliminated within 4 h. The greatest T4S deposition by tissue weight was observed in the liver, followed by the kidney and spleen, while M2 was most concentrated in the kidney followed by the liver and spleen. These findings indicate that T4S and M2 were distributed mainly in tissues with an abundant blood supply and were rapidly excreted in urine. View Full-Text
