Abstract

Two arylbutadiene dimers of the 3-aryl-4-styrylcyclohexene series together with a novel C6-C4 monomer (2-(3,4-dimethoxystyryl)ethanol) have been isolated from Zingiber cassumunar. Due to their co-occurrence and the chemical similarity of one portion of the molecules, a possible biosynthetic relationship between the cyclohexene dimers and the phenylnaphthaquinones of Z. cassumunar, based on Diels-Alder reactions, is suggested.
