Isoflavonoid glycosides of Dalbergia paniculata: The constitutions of dalpanitin and dalpatin
Isoflavonoid glycosides of Dalbergia paniculata: The constitutions of dalpanitin and dalpatin
- Tetrahedron, 28, p.5377-5384, 1972 .
Further examination of the extractives of the seeds of Dalbergiapmiculato has yielded three new isotlavonoid glycosides dalpanin, dalpanitin and dalpatin. The elucidation of the structures of the latter two compounds is presented. Dalpanitin is shown as 8-C-B-D-glucopyranosyl-3'-methoxy_4'.5.7vone (VII)and dalpatin as 2',6dimethoxy-4',5'-methylenedioxy-7-glucosyloxyisoflavone (XX)by spectral and chemical evidence.
