  • Analysis of procyanidins in chocolate by reversed-phase high-performance liquid chromatography with electrospray ionization mass spectrometric and tandem mass spectrometric detection

Abstract

The analysis of procyanidins in crude chocolate extracts by reversed-phase high-performance liquid chromatography (HPLC) with electrospray ionization mass Spectrometry (MS) is described in this report. Catechin monomers and procyanidin oligomers (dimers to hexamers) were identified according to the mass of the single charged pseudomolecular ion ({M-H}-). Identification was further confirmed by collision-induced dissociation MS-MS analysis, which in addition permitted the identification of double chared pentameric, hexameric, and heptameric ions. This study demonstrates the capability of the combination of HPLC and modern ion trap mass analyzers to significantly reduce sample preparation and analysis time in combination with high specificity and structural information for compound identification.
