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 13C NMR data for some of these known compounds are also included.
