Phenolic acids have been determined in the Tunisian currant palm tree products, dates and legmi (a fermented sap extract). Reversed phase high performance liquid chromatography has been used and results confirmed for the more concentrated compounds by thin-layer chromatography on silica gel. Gallic acid, protocatechuic, p-hydroxybenzoic, syringic, vanillic, caffeic, p-coumaric and ferulic acids have been identified and the origin of these compounds is discussed. The analysed palm tree products are rich in phenolic acids and are characterized by a high concentration in one particular phenolic acid: ferulic acid for dates, gallic acid for legmi. © 1987.
