Phaeoside, a novel galactoside of hydroxymanoyl oxide from the gibberellin A1-producing Phaeosphaeria sp. L487.
Isolation and examination of a diterpene glycoside from the culture filtrate of the gibberellin A(1)-producing Phaeosphaeria sp. L487 allowed us to identify a novel fungal galactoside of hydroxymanoyl oxide together with (-)-ent-13-epi-manoyl oxide. It was designated phaeoside and determined to be 1alpha-hydroxy-ent-13-epi-manoyl oxide 1-O-beta-D-galactopyranoside based on its chemical degradation and spectroscopic methods. This is the first report of the isolation of a diterpene galactoside from fungi.
