Abstract
Novel antioxidative phenylpropanoid-substituted tocopherol derivatives, prunusols A and B, were isolated from the leaf wax of Prunus grayana Maxim., and their structures were fully characterized by spectroscopic and synthetic methods. Prunusols A and B were found to be the conjugates of γ-tocopherol and p-coumaric acid, which are diastereoisomers of each other. They showed almost the same antioxidative activity as α-tocopherol in a water/alcohol system measured by thiocyanate and TBA methods.
