Phenolic acids such as syringic, p-coumaric, vanillic, caffeic, 3,4-di
hydroxybenzoic and gallic acid, which are present in wines and other a
lcoholic drinks, were determined by capillary electrophoresis: using a
n uncoated fused-silica capillary. The optimum conditions for their se
paration were investigated. Examples of electropherograms of phenolic
acids contained in some Italian wines are reported.
