Task: Please create a text description for a molecule based on its representation.
Molecule SMILES: C=CC(C)(C)c1c(O)cc(O)c2c(=O)c3c(oc12)C=C(O)C(=O)C3(CC=C(C)C)CC=C(C)C
Constraint: Answer the question with full sentences.
Result: The molecule is a member of the class of xanthones that is 1H-xanthene-2,9-dione substituted by hydroxy groups at positions 3, 6 and 8, a 2-methylbut-3-en-2-yl group at position 5 and two prenyl groups at position 1. IT has been isolated from Hypericum erectum and Hypericum sampsonii. It has a role as a plant metabolite. It is a member of xanthones and a polyphenol.
