Triterpenes of E. tirucalli L. latex

Triterpenes comprise 80% of the chemical composition of E. tirucalli latex1,2. A rich fraction of these compounds was analyzed by GC-MS and profile of euphane, tirucallane and with pentacyclic skeletons were detected. Euphol and tirucallol were the major compounds, with retention times of 22.698 and 23.222 minutes, respectively (Fig.1). Minor compounds were identified by comparison with the NIST library and EI-MS (Fig.2). The characterization of triterpenes aims at chemical mapping of species.
