Abstract

Three quassinoids, iandonosides A and B and iandonone, were isolated from the root of Eurycoma harmandiana, along with five known quassinoids, casteloside B, 13 beta, 21-dihydroeurycomanone, chaparrinone, glaucarubolone and ailanquassin B as well as the coumarin, scopoletin. The structural elucidations were based on analyses of spectroscopic data.
