A new bicoumarin derivative, bidysoxyletine (1), was isolated from the leaves of Dysoxylum parasiticum (Osbeck) Kosterm. The structure of 1 was elucidated by analysis of NMR, UV, IR, HR-ESITOFMS, and DDFT approach using the B3LYP exchange-correlation function for 13 C NMR and UV spectroscopic data. The results indicated that the structure of 1 possessed a dibenzonapthyrone skeleton.
