Task: Please create a description for a molecule based on its representation.
Molecule SMILES: COC(=O)[C@@H]1C[C@H](O)[C@]2(C)CC[C@]3(C)C(=CC[C@@H]4[C@@]5(C)CCC(=O)C(C)(C)[C@@H]5CC[C@]43C)[C@H]2[C@H]1C
Constraint: Answer the question with complete sentences.
Result: The molecule is a pentacyclic triterpenoid with formula C31H48O4, originally isolated from the roots of Tripterygium regelii. It has a role as a plant metabolite. It is a pentacyclic triterpenoid, a cyclic ketone, a secondary alcohol and a methyl ester. It derives from a hydride of an ursane.
