Abstract

A new isoflavonostilbene which has been called maackiasin has been isolated from an ethanolic extract of the heartwood ofMaackia amurensis and its structure has been established by spectral methods. The maackiasin molecule is constructed of fragments of the isoflavone retusin and of 3,3′,4′,5-tetrahydroxystilbene linked by a diether bond. The dioxane grouping connecting the two fragments is constructed from the hydroxyls at C-7 and C-8 of the isoflavone and the vinyl grouping of the stilbene. Maackiasin is the first representative of a new type of natural polyphenols.
