The invention relate to stilbene derivatives having formula I wherein R3, R4 and R5 and R3', R4' and R5' are identical or different and represent H, OH, O-alkoxy or hal, said alkoxy group being a C1-C6 alkoxy and "hal" being F, Cl or CF3, with the proviso that one of R4', R3 and R5 or R4, R3' and R5' does not represent OH, OCH3 or OCH2 CH3 when the two other subtituents are both OH, OCH3, OCH2CH3, respectively, and the symmetrical derivatives. Use of said stilbene derivatives particularly as pharmaceutical compositions and food additives.
