Abstract
In experiments with C14-labelled compounds, shikimic acid, phenylalanine, phenyllactic acid, and metatyrosine were found to be precursors of the terphenylquinone pigment volucrisporin. It is suggested that the pigment is biosynthesized by the self-condensation of two molecules of an unbranched phenyl-propanoid intermediate, and that hydroxylation of the phenyl rings in the meta position occurs before the condensation step.
