Abstract
Reversed-phase high-performance liquid chromatography-mass spectroscopy (HP LC-MS) and capillary electrophoresis-mass spectroscopy (CE-MS) have been co mpared for he analysis of phenolic compounds in diethyl ether extracts of r ed wines. MS was performed in the electrospray negative-ionization mode. De spite the much higher separation efficiency of CE compared with LC, LC-MS f urnishes far superior information for elucidation of the structure of the c onstituents. LC-MS enabled the identification of twenty-four compounds wher eas only thirteen were characterized by CE-MS.
