The Detection of Polyphenolics in Food and Drink by LC/MS/MS
14 Jun 2012
Catechins are polyphenolic antioxidant plant metabolites found in a variety of foods including fruits, wine, beer, chocolate, and most abundantly in tea. This study shows the use of LC-MS for the determination of 8 known catechins in samples such as tea and wine. The method demonstrates the efficient separation and detection and of these compounds by LC-MS and uses advances in HPLC column phases and high pressure separations to improve sensitivity and speed up the analysis.
