Abstract: The DL-α-tocopherol neutral radical (α-T) produced by the hydrogen abstraction of DL-α-tocopheral (α-TH) with di-tert-butylperoxide (DBPO), 2,2'-azo-(2,4-di-methyl-valeronitrile) (ADVN), γ-Al_2O_3 or SiO_2/Al_2O_3 has been studied by EPR spec-troscopy. From these experimental results, the mechanism of α-T radical generation is discussde.

Key words: DL-α-tocopherol, Neutral radical, EPR
