A New Sesquiterpene Glycoside from Pittosporum kerrii

A phytochemical study of secondary metabolites produced by Pittosporum kerrii Craib has led to the isolation of a novel oxygenated sesquiterpene glycoside, pittosporam A (1), together with four known compounds (2–5). The structure of the new metabolite was established on the basis of its detailed spectroscopic analyses.
