phytochemical characteristics of Bergamot Oranges from the ionian islands of greece a multi analytical approach with emphasis in the distribution of neohesperidose flavanones
Food Chemistry, 2021Co-Authors: Evangelia Tsiokanos, N Tsafantakis, Aikaterini Termentzi, Nektarios Aligiannis, Leandros Skaltsounis, Nikolas FokialakisAbstract:Abstract The present study describes the peculiar phytochemical characteristics of Bergamots cultivated in distinct islands of the Ionian Sea. Ultrahigh-performance liquid chromatography high-resolution mass spectrometry (UHPLC-HRMS) supported by 1 and 2D NMR spectroscopy was used for unambiguous metabolic profiling of albedo, flavedo and juice samples. Profile differences were determined using a multi-analytical clustering approach based on high-performance thin-layer chromatography fingerprints and UHPLC-HRMS data. Finally, a validated HPLC method offering good precision (0.12–0.94%) and accuracy (95.25–103.93%) was proposed for the quantification of the major flavanones. A total of 37 secondary metabolites were characterized belonging to flavonoids, limonoids and coumarins. Their distribution was tissue-dependent and varied significantly from Bergamots of other geographical locations. Surprisingly, neoeriocitrin was the major flavanone, reaching 1.69 ± 0.05 g/L in the juice and 5.24 ± 0.12 mg/g in albedo. This is the highest reported amount among Citrus species, rendering Ionian Bergamots a promising candidate for novel functional products.
