摘要：Changes in plasma and RBC α-tocopherol after intravenous and oral administration of dl -α-tocopheryl acetate were investigated using vitamin E-deficient rats and were compared with those following the administration of d -α-tocopherol, which is the most active and natural form of tocopherol. 1. Intravenous administration: By the administration of dl -tocopheryl acetate, the elevated plasma tocopherol levels were higher at 6h than those elevated by d tocopherol, but the RBC tocopherol was lower 6 h after the infusion of dl -tocopheryl acetate than after d tocopherol infusion. The tocopheryl acetate incorporated into the RBCs remained for 24h after the administration of tocopheryl acetate, the acetate then becoming undetect-able in plasma. 2. Oral administration: The tocopherol elevated in plasma and RBC was only the α-form and not tocopheryl acetate. In both plasma and RBCs, tocopherol levels were higher after the administration of d tocopherol than after dl -tocopheryl acetate administration, and more was found in RBCs.
