A strain of Seiridium cupressi, a fungus causing a canker disease of cypress (Cupressus sempervirens) in Greece, produces several phytotoxins in culture. Two of them were identified as seiridin and iso-seiridin, the butenolides previously isolated from another cypress pathogen, S. cardinale. A third phytotoxin, which is present in small amounts in the culture filtrates of S. cupressi and is not produced by S. cardinale, was identified as a new macrolide which we have called seiricuprolide. Its structure was established by spectroscopic analysis of the metabolite and of some key derivatives.

Abstract
A strain of Seiridium cupressi, a fungus causing a canker disease of cypress (Cupressus sempervirens) in Greece, produces several phytotoxins in culture. Two of them were identified as seiridin and iso-seiridin, the butenolides previously isolated from another cypress pathogen, S. cardinale. A third phytotoxin, which is present in small amounts in the culture filtrates of S. cupressi and is not produced by S. cardinale, was identified as a new macrolide which we have called seiricuprolide. Its structure was established by spectroscopic analysis of the metabolite and of some key derivatives.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
