Task: Please create a text description for a molecule based on its representation.
SMILES: C=C1C(=O)O[C@H]2C[C@@H](C)[C@@H]3[C@@H](OC(C)=O)C[C@H](OC(C)=O)[C@@]3(C)[C@@H](O)[C@H]12
Constraint: Answer the question with full sentences.
Result: The molecule is a sesquiterpene lactone that is decahydroazuleno[6,5-b]furan-2(3H)-one substituted by acetyloxy groups at positions 5 and 7, a hydroxy group at position 4, methyl groups at positions 4a and 8 and a methylidene group at position 3. It has been isolated from the aerial parts of Inula hupehensis. It has a role as a metabolite, an anti-inflammatory agent and a plant metabolite. It is a gamma-lactone, an organic heterotricyclic compound, a sesquiterpene lactone, an acetate ester and a secondary alcohol.
