A new furanoflavone, named sanaganone, was isolated from the root bark of Millettia sanagana in addition to four known compounds, pongamol, lanceolatin B, kanjone and 5-methoxy furano [7,8:4″,5″] flavone. The structure of the new compound was elucidated by spectroscopic analysis, including 2D NMR techniques (DQF COSY, HETCOR, long-range HETCOR and NOESY), as 2‴,2‴-dimethylpyrano [5,6:5‴,6‴] furano [7,8:4″,5″] flavone.
