Abstract: | The phytochemical investigation of the stems of Fissistigma maclurei Merr. led to the isolation of a new eudesmane-type sesquiterpene 6α,12-dihydroxy-4(15)-eudesmen- 1-one (1), together with seven known eudesmane-type sesquiterpenes (2–8) and four known aporphine-type alkaloids (9–12). The structures of these compounds were elucidated using comprehensive spectroscopic methods. All compounds were isolated from the F. maclurei for the first time. The chemotaxonomic significance of the isolates was also discussed. |
