Summary

Reversed-phase high-performance liquid chromatography-mass spectroscopy (HPLC-MS) and capillary electrophoresis-mass spectroscopy (CE-MS) have been compared for the analysis of phenolic compounds in diethyl ether extracts of red wines. MS was performed in the electrospray negative-ionization mode. Despite the much higher separation efficiency of CE compared with LC, LC-MS furnishes far superior information for elucidation of the structure of the constituents. LC-MS enabled the identification of twenty-four compounds whereas only thirteen were characterized by CE-MS.
