| Abstract: | Object The analysis of oligomeric procyanidins in crude grape seed extracts was performed by reversed-phase high-performance liquid chromatography with electrospray ionization mass spectrometry (RP-HPLC/ESI-MS). Methods Procyanidin monomer and oligomers were identified according to the mass of the charged pseudomolecular ion [M-H]. Results Three monomers, seven dimmers and three trimers were tentatively identified. Conclusion This study demonstrates the capability of the combination of RP-HPLC with ESI-MS to analyze the composition of oligomeric procyanidins in grape seed extracts. |
