Abstract

A process for producing a hydroxystilbene derivative represented by formula (1) (wherein X-Xindependently represent a hydrogen atom, a hydroxy group, a saturated or unsaturated linear or branched alkoxy group having 1-10 carbon atoms, or a saturated or unsaturated linear or branched alkyl group having 1-10 carbon atoms; Zand Zindependently represent a hydrogen atom, or a group represented by the formula (2) (wherein Xand Xindependently represent a hydrogen atom, a hydroxy group, a saturated or unsaturated linear or branched alkoxy group having 1-10 carbon atoms, or a saturated or unsaturated linear or branched alkyl group having 1-10 carbon atoms); and Zand Zmay be the same as or different from each other; wherein X-Xmay be the same as or different from one another), which is characterized by heating a 4-hydroxycinnamic acid compound and a hydroxystilbene compound in the presence of a metal salt.
