| Description | (3AR,4R,6R,6aS,7S,9aR,9bR)-7-(acetyloxy)-9-methyl-3-methylidene-2-oxo-3,3a,4,5,6a,7,9a,9b-octahydro-2H-spiro[azuleno[4,5-b]furan-6,2'-oxirane]-4-yl (2E)-4-hydroxy-2-methylbut-2-enoate 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. Eupachifolin B is found in Eupatorium chinense. Based on a literature review very few articles have been published on (3aR,4R,6R,6aS,7S,9aR,9bR)-7-(acetyloxy)-9-methyl-3-methylidene-2-oxo-3,3a,4,5,6a,7,9a,9b-octahydro-2H-spiro[azuleno[4,5-b]furan-6,2'-oxirane]-4-yl (2E)-4-hydroxy-2-methylbut-2-enoate. |
