Abstract A new symmetric naphthoquinone dimer, dilapachone ( 1 ), and a novel asymmetric naphthoquinone dimer, adenophyllone ( 2 ), were isolated from the heartwood of Heterophragma adenophyllum. Their structures were elucidated by spectroscopic means including high‐resolution mass, UV, IR, 1D‐ and 2D‐NMR spectroscopy.
