Abstract
Two new secondary metabolites, the phenylpropanoid 3-(2′,4′,5′-trimethoxyphenyl)propanoic acid (1) and the sesquiterpene (+)-1β,4β,6α-trihydroxyeudesmane (2) were isolated from the heartwood of Cordia trichotoma Vell., along with the known sesquiterpenes (D)-1β,4β,7α- trihydroxyeudesmane (3) and (+)-1β,4β,11-trihydroxyoppositane (4). Their structures were elucidated by means of spectroscopic data interpretation, mainly 1D and 2D NMR and mass spectrometry.
