Abstract
The crystal structure of the title compound, C30H48O3, a triterpene extract ed from the resin of Protium crenatum Sandwith, is reported. The aliphatic acidic side chain is attached to the tirucallene four-ring system on its al pha -face and is extended by 7.248 (5) Angstrom in the 'left-hand' orientat ion.
