✦ Synopsis


Abstract

The ^13^C NMR spectra of eight triterpenes are recorded and all carbon shifts have been assigned. The data are in agreement with the structures assigned to the rare lupanediol, lup‐20(29)‐ene‐3Ξ±,23‐diol, and other lupane triterpenes isolated from the Sri Lankan Glochidion species (Euphorbiaceae). The ^13^C NMR data of some triterpenes, aleuritolic acid derivatives and taraxerane derivatives are compared.
