Some phytochemical investigations were carried on the roots of Ouratea turnarea. This work led to the isolation of menisdaurin, epicatechin, β-sitosterol-3-O-β-D-glucopyranoside and astragenol-3-O-β-D-xylopyranoside, the last compound is reported for the first time from the Ochnaceae family. Their structures were established by direct interpretation of their spectral data, mainly HRESI-MS, 1D and 2D NMR, and by comparison with literature.
