Task: Please create a description for a molecule based on its representation.
SMILES: CC(C)CCC[C@H](C)[C@@H]1CC[C@]2(C)C3=CC[C@H]4C(C)(C)C=CC(=O)[C@]4(C)[C@H]3CC[C@@]12C
Constraint: Answer the question with complete sentences.
Result: The molecule is a tirucallane triterpenoid that is (13alpha,14beta,17alpha,20S)-lanosta-2,7-dien-1-one substituted by an oxo group at position 1. It has been isolated from the stem and stem barks of Cornus walteri. It has a role as a plant metabolite. It is a tirucallane triterpenoid, a cyclic terpene ketone and an enone.
