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.
在之前的一篇论文中,我们报道了从陈达伯格(Dalbergia odorifera T. CHEN)(豆科植物)的心材中分离出 27 种单体和二聚异黄酮衍生物,并阐明了其中 12 种单体和 5 种二聚异黄酮的结构,从而展示了天然生物异黄酮的新实例。在对该植物的继续研究中,我们对分离出的未定性化合物中的四种新的二聚黄酮类化合物和一种新的芳基苯并呋喃进行了结构测定。
