Abstract
The canaric acid 1 was isolated from the leaves of Rudgea jasminoides. Comp ound 1 is a seco-lupane derivative and its structure was established on the basis of spectral data, mainly by 1D and 2D NMR experiments. Sitosterol, s tigmasterol and ursolic and oleanolic acids were also isolated.
