A new isoflavan, (3S)-1′,4′-dihydroxy-6,7,8,2′,3′-pentamethoxyisoflavan (1), together with six known compounds, abruquinone G (2), abruquinone B (3), isoliquiritigenin (4), gallic acid (5), ethyl gallate (6), and 1-O-galloyl-β-D-glucose (7) were isolated from Abrus precatorius. Their structures were elucidated on the basis of physical and spectral analysis, respectively. Compounds 1, 4, and 7 were isolated from this plant for the first time.
