Metabolite Identification
Common NameAnnuolide G
DescriptionAnnuolide G belongs to the class of organic compounds known as guaianolides and derivatives. These are diterpene lactones with a structure characterized by the presence of a gamma-lactone fused to a guaiane, forming 3,6,9-trimethyl-azuleno[4,5-b]furan-2-one or a derivative. Based on a literature review a small amount of articles have been published on Annuolide G.
