Chemical constituents of Musa cv. ‘Thepanom’ (BBB) or "praying hands" banana (Musaceae) were investigated by means of chromatographic techniques. A new natural product of the phenylphenalenone type, 3-hydroxy-4-phenyl-1H,3H-benzo[de]isochromen-1-one, and two known natural products, methoxyanigorufone and isoanigorufone, were isolated and identified by NMR spectroscopy and mass spectrometry. Additionally, by HPLC analysis, three condensed dimeric phenylphenalenones, namely anigorootin, 4′-hydroxyanigorootin, 4′,4″-dihydroxyanigorootin, were identified.KEYWORDS
