Isoflavones from Ficus nymphaeifolia

A new isoflavone, 5,7-dihydroxy-4\u27-methoxy-3\u27-(2,3-dihydroxy-3-methylbutyl)isoflavone was isolated from the stem bark of Ficus nymphaefolia Mill. (Moraceae) together with eight known isoflavones: genistein, erycibenin A, cajanin, 5,7,2\u27-trihydroxy-4\u27-methoxyisoflavone, erythrinin C, alpinumisoflavone, derrone and 3\u27-(3-methylbut-2-enyl)biochanin A.
