A new isoflavone, 5,7-dihydroxy-4'-methoxy-3'-(2,3-dihydroxy-3-methylbutyl)isoflavone (1) was isolated from the stem bark of Ficus nymphaefolia Mill. (Moraceae) together with eight known isoflavones: genistein, erycibenin A, cajanin, 5,7,2'-trihydroxy-4'-methoxyisoflavone, erythrinin C, alpinumisoflavone, derrone and 3'-(3-methylbut-2-enyl)biochanin A. Their structures were established by spectral analysis including 1D and 2D NMR experiments.
