Abstract

This paper deals with an extensive analytical approach, which uses two complementary tandem mass spectrometry techniques, to characterize the chlorogenic acids (CGAs) present in a typical Italian sweet cherry variety (cv Ferrovia). Sixteen monoacyl-quinic acids and esters, five diacyl-quinic acids, three caffeoyl-quinic acids glycosides, and two caffeic acid hexoses were detected by HPLC-MSn analyses (MSn up to MS4), among which four methyl coumaroyl quinate and three methyl caffeoyl quinate isomers were tentatively identified in sweet cherries for the first time. HPLC-MS/MS analyses through multiple reaction monitoring (MRM) experiments showed that trans-3-O-caffeoylquinic acid, cis-3-O-coumaroylquinic acid, trans-3-O-coumaroylquinic acid, trans-5-O-caffeoylquinic acid, and methyl-3-O-caffeoyl quinate were the main CGAs in the mature berries of cv Ferrovia. Considering that CGAs can have several health benefits depending on their amount but also on their structural features, the results of this study provide new insight into the knowledge of the quali-quantitative profile of these phytochemicals in a widespread fruit such as sweet cherry. © 2018 Elsevier Inc.
