| Description | (2S,4S)-4-[(3aR,7S,8aR)-7-methyl-3-methylidene-2-oxo-2H,3H,3aH,4H,7H,8H,8aH-cyclohepta[b]furan-6-yl]-4-hydroxybutan-2-yl acetate belongs to the class of organic compounds known as xanthanolides. These are sesquiterpenoids with a structure based on the xanthanolide skeleton consistsing of a cycloheptane ring usually attached to a four-carbon chain (at carbon 1 ) and a methyl group (at carbon 10), and fused to a five-member lactone ring (sharing carbons 7 and 8). The lactone ring can be conjugated with a methyl or methylene group at position 11. 8-epi-isoxanthanol is found in Pulicaria undulata and Xanthium strumarium . 8-epi-isoxanthanol was first documented in 2012 (Hegazy, M-E. F., et al.). Based on a literature review very few articles have been published on (2S,4S)-4-[(3aR,7S,8aR)-7-methyl-3-methylidene-2-oxo-2H,3H,3aH,4H,7H,8H,8aH-cyclohepta[b]furan-6-yl]-4-hydroxybutan-2-yl acetate. |
