  author={P. M{\'a}ximo and A. Lourenço},
Abstract A new pterocarpan has been isolated from Ulex parviflorus . The structure of this compound, (−)-2,3,4-trimethoxy-8,9-methylenedioxypterocarpan, was established by spectroscopic means. In addition, the known pterocarpans, (−)-maackiain, (−)-4-methoxymaackiain, (−)-2-methoxymaackiain, the isoflavone isoderrone and the triterpenoid soyasapogenol B were isolated from the same source. New 13 C NMR data for some of these known compounds are also included.
