摘要
Targeting the discovery of novel natural products, the roots of Dalbergia spinosa Roxb has yielded a new isoflavone apioglycoside, 5-hydroxy-6-methoxy-3',4'-methylenedioxy-7-[(6-O-beta-D-apiofuranosyl-beta-D-glucopyranosy) oxy]isoflavone (dalspinin-7-O-beta-D[apiofuranosyl (1 -> 6)] glucopyranoside) (1), together with the known isoflavones, dalspinin (2), dalspinosin (3) and caviunin (4). Their structures were elucidated on the basis of extensive spectral and chemical evidence. To the best of our knowledge, this is the first report of the occurrence of an apioglucoside of dalspinin in Nature.
