Abstract

• Two pimarane diterpenes structurally related to sphaeropsidins were isolated from the liquid culture of Sphaeropsis sapinea f. sp. cupressi, a plant pathogenic fungus causing a form of canker disease of Italian cypress (Cupressus sempervirens L.). The two metabolites, characterised by spectroscopic methods, were named sphaeropsidins D (0.40 mg l(-1)) and E (0.16 mg l(-1)). The same fungus produced sphaeropsidins A, B and C, sphaeropsidone and episphaeropsidone, which proved to be phytotoxic to cypress, and chlorosphaeropsidone and epichlorosphaeropsidone showing no phytotoxicity. Sphaeropsidin D assayed at 0.1 mg ml(-1) on severed cypress twigs caused leaf browning and necrosis on Cupressus macrocarpa, but no symptoms were observed on C. sempervirens and C. arizonica. Symptoms appeared in a period of time (6 days after toxin-treatment) shorter than that for sphaeropsidin A. Sphaeropsidin E assayed at 0.2 mg ml(-1) did not produce any symptom on the same cypress species tested with sphaeropsidin D. (literal)
