摘要：

A new isoflavanone, (-)2',4'-dihydroxy-6-prenyl-7-methoxyisoflavanone, eryvellutinone, was isolated from the stem bark of Erythrina vellutina Willd. The use of spectroscopic techniques, mostly 1D and 2D NMR, led us to the unambiguous assignments of all protons and carbons of the molecule. Copyright (C) 1996 Elsevier Science Ltd
