Abstract
This contribution describes the structure elucidation of dimeric and trimeric oxidation products derived from natural (2__R__,4′R,8′R)‐α‐ and (2__R__,4′R,8′R)‐γ‐tocopherol, the most important lipid‐soluble vitamin E compounds and antioxidants in biological systems. Complete ^1^H and ^13^C NMR signal assignments have been obtained by combinations of one‐ and two‐dimensional NMR techniques. These structural investigations include full determination of stereochemistry and a study of dynamic processes. Copyright © 2001 John Wiley & Sons, Ltd.
