Antifungal biflavones from Cupressocyparis leylandii.
From the leaves of Cupressocyparis leylandii (Cupressaceae) cupressuflavone, 4-O-methylcupressuflavone, amentoflavone, 7-O-methylamentoflavone, 4-O-methylamentoflavone and hinokiflavone were isolated. 1H- and 13C-NMR data for 4-O-methylcupressuflavone are given for the first time. The biflavones from cultivar varieties of C. leylandii (Naylor's Blue, Castlewellan Gold) were chromatographicaly (HPLC) compared. The antifungal activity of cupressuflavone and 4-O-methylcupressuflavone against Alternaria alternata, Cladosporium oxysporum, Fusarium culmorum and F. avenaceum was assayed.
