In this manuscript, we report the isolation and characterization of two secondary metabolites produced by a Gnomoniopsis castanea strain isolated in the Campania region (Italy) from chestnut galls infested with Dryocosmus kuriphilus. The compounds, purified from the fungal culture filtrate by using preparative HPLC-DAD, showed the same spectroscopic data of abscisic acid and 1?,4?-diol of abscisic acid. Phytotoxic activity of the isolated metabolites on chestnut leaves has been also observed.

Abstract
In this manuscript, we report the isolation and characterization of two secondary metabolites produced by a Gnomoniopsis castanea strain isolated in the Campania region (Italy) from chestnut galls infested with Dryocosmus kuriphilus. The compounds, purified from the fungal culture filtrate by using preparative HPLC-DAD, showed the same spectroscopic data of abscisic acid and 1?,4?-diol of abscisic acid. Phytotoxic activity of the isolated metabolites on chestnut leaves has been also observed.File in questo prodotto:
