摘要：

A new isoflavan-quinone, 3',6'-diketo-7-hydroxy-8,2',4'-trimethoxyisoflavan, named laurentiquinone and a new flavonol, 3,7,4'-trihydroxy-3',5'-dimethoxyflavone, named laurentinol, have been isolated from the heartwood of Millettia laurentii in addition to two known isoflavones, calycosin and glyricidin. The structures of the new compounds were elucidated from spectral studies. C-13-NMR spectral data of the known isoflavones are reported here for the first time. (C) 1999 Elsevier Science Ltd.
