The phytochemical study of the leaves of Eucryphia cordifolia (Cunoniaceae) allowed for the isolation of six compounds: the triterpenes betulin (1) and 28-acetoxy betulin (3), the steroid β-sitosterol (2), the flavonol quercetrin (4), the flavanonol astilbine (5) and the flavanol catechin (6). The structures of the isolated compounds were clearly assigned through 1D and 2D-NMR, MS studies, and compared to previously described data. This is the first report on the isolation of compounds 1–4 and 6 from the genus Eucryphia. The chemotaxonomic importance of the isolated compounds within the family of Cunoniaceae-related plants is discussed.
