摘要: A new flavanone glycoside, (2S)5,7,4_-trihydroxyflavanone-8-C-_-D-(6__-O-acetyl)glucopyranoside (1), together with six known flavonoids, isohemiphloin (2), vitexin (3), cirsimaritin (4), hispidulin (5), apigenin (6), and eupatorin (7), was isolated from the leaves and stems of Abrus precatorius. Their structures were elucidated on the basis of physical and spectral analysis. Rotamers exist for compounds 1, 2, and 3. Compounds 1–3, 6, and 7 were isolated from this plant for the first time.
