Abstract

Aspernolide A and butyrolactones I and II showed inhibitory activities against soybean lipoxygenase. All of them also had DPPH (2,2-diphenyl-1-picrylhydrazyl) radical-scavenging activity. An analysis of the mechanism for radical scavenging allowed us to deduce that aspernolide A was converted to a quinone methide by a reaction with two molecules of the DPPH radical.
