Simultaneous GC-MS determination of free and bound phenolic acids in Slovenian red wines and chemometric characterization

摘要

Several phenolic acids (PAs), caffeic, vanillic, syringic, p-coumaric and ferulic acid, found in Slovenian red wines were studied using gas chromatography and mass spectrometry (GC-MS). For isolation of the PAs from wine samples, solid phase extraction (S
