In a previous paper, we reported the isolation of the twenty-seven monomeric and dimeric isoflavonoid derivatives from the heartwood of Dalbergia odorifera T. CHEN (Leguminosae) and the structure elucidation of twelve monomeric and five dimeric isoflavonoids, which presented novel examples of naturally occuring biisoflavonoids. In a continuing study on this plant, we deal with the structure determination of four new dimeric flavonoids and a new arylbenzofuran among the uncharacterized compounds among the isolated ones.
