Abstract

Three known preussomerins, G (1), H (2) and I (3), and three new representatives, J (4), K (5) and L (6), were isolated from an endophytic fungus, a Mycelia sterila, from Atropa belladonna. Their absolute configuration was determined by comparison of calculated and experimental CD spectra.
