Abstract

A citrinin dimer, named dicitrinol (3), was isolated from extracts obtained from a rice cultivation of Penicillium janthinellum, a fungus found in fruits of Melia azedarach. Dicitrinol (3) was isolated by classical chromatographic procedures, and identified by MS, and 1D‐ and 2D‐NMR data. A biosynthetic scheme is proposed for this new dimerization of citrinin. Dicitrinol (3) was shown to be slightly weaker than citrinin regarding bacterial inhibition.
