Common Name

3,6,9-trimethylidene-2-oxo-8-{[3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}-octahydroazuleno[4,5-b]furan-4-yl 2-ethyl-2-hydroxy-3-oxobutanoate

Description

3,6,9-Trimethylidene-2-oxo-8-{[3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}-dodecahydroazuleno[4,5-b]furan-4-yl 2-ethyl-2-hydroxy-3-oxobutanoate 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. 3,6,9-trimethylidene-2-oxo-8-{[3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}-octahydroazuleno[4,5-b]furan-4-yl 2-ethyl-2-hydroxy-3-oxobutanoate is found in Crepis capillaris, Crepis mollis and Crepis pyrenaica. Based on a literature review very few articles have been published on 3,6,9-trimethylidene-2-oxo-8-{[3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}-dodecahydroazuleno[4,5-b]furan-4-yl 2-ethyl-2-hydroxy-3-oxobutanoate.
