Abstract: A new pterocarpan glycoside, (–)-maackiain 3-O-6'-O-acrylyl-β-D-galactopyranoside(1) was isolated from the whole parts of Caragana jubata(pall.) Poir., together with three known pterocarpan glycosides, (–)-maackiain 3-O-6'-O-acetyl-β-D-glucopyranoside(2), (–)-maackiain 3-O-β-D-glucopyranoside(3) and (–)-maackiain 3-O-β-D-galactopyranoside(4). All the compounds were isolated from the title plant for the first time. The structure of the new compound was established on the basis of detailed 1D, 2D NMR and circular dichroism spectroscopic analyses. All the compounds were evaluated for their cytotoxic activities against three tumor cell lines, A549, HL-60 and P388.
