To our knowledge, reverse phase of high performance liquid chromatography was firstly developed to analyze the metabolites of 7-tocopherol with ideal results. Meanwhile, Gas chromatography/Mass chromatography were used to analyze the structures of unknown metabolites of 7-tocopherol and a main unknown metabolite was identified as a side chain ω- hydroxylate of 7-tocopherol.The kinetic results of of 7-tocopherol reacted in the S9 of male SD-rat liver showed that the optimal time was 45 min; the optimal concentration of S9 5 mg/ml; the optimal concentration of NADPH 1 mM; and the optimal concentration of 7-tocopherol 8 μg/ml. The result of γ-tocopherol metabolized in the S9 of male SD-rat was the best; male Brazil turtle better; and male cobia worst.
