Metabolomic Profiling of Wines Produced in China and France by UHPLC-ESI/QTOF-MS

摘要

UHPLC-QTOF tandem mass spectrometry has been demonstrated as a powerful technique for metabolomic profiling of wines from various sources; Data mining technique as MPP allows aligning and filtrating data more rapidly and efficiently; Significant markers have been obtained among the wines from four major French Chateaux, which can not only discriminate the four groups of wines, but also differentiate wines from Chinese source. Assignment of unknown was also consistent with the measurement conducted by other techniques; A PLSDA model has been created, excellent accuracy and reasonable confidence have been achieved. More samples from clear sources are required for a better model; Identification of marker with target MS/MS followed by molecular structure correlation generated some potential candidates, which are under further investigation.
