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.
