The I3C 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-3cu,23-diol, and other lupane triterpenes isolated from the Sri Lankan Glochidion species (Euphorbiaceae). The I3C NMR data of some triterpenes, aleuritolic acid derivatives and taraxerane derivatives are compared.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
