distribution of c and o glycosyl flavonoids 3 hydroxy 3 methylglutaryl glycosyl flavanones and Furocoumarins in citrus aurantium l juice
Food Chemistry, 2011Co-Authors: Davide Barreca, Ersilia Bellocco, Corrado Caristi, Ugo Leuzzi, Giuseppe GattusoAbstract:Abstract The qualitative and quantitative flavonoid and Furocoumarin composition of crude sour orange (Citrus aurantium L.) juice was determined via reverse-phase LC–DAD–ESI–MS–MS analysis. In a single course, a comprehensive chromatographic profile of 14 compounds (Furocoumarins, C- and O-glycosyl flavonoids) was obtained. Seven flavonoids and a Furocoumarin were identified for the first time in sour orange juice: three C-glucosides (lucenin-2, vicenin-2 and lucenin-2, 4′-methyl ether), two O-glycosides (rhoifolin 4′-glucoside and narirutin 4′-glucoside), two 3-hydroxy-3-methylglutaryl flavanone glycosides (melitidin and brutieridin) and a Furocoumarin (epoxybergamottin). Furthermore, the antioxidant activity of sour orange juice was assessed by means of ABTS + and DPPH radical scavenging assays.

distribution of flavonoids and Furocoumarins in juices from cultivars of citrus bergamia risso
Journal of Agricultural and Food Chemistry, 2007Co-Authors: Giuseppe Gattuso, Davide Barreca, Corrado Caristi, Claudia Gargiulli, Ugo LeuzziAbstract:HPLC separation of flavonoids and Furocoumarins in the crude juices of three cultivars of Citrus bergamia Risso (“Castagnaro”, “Fantastico”, and “Femminello”) was carried out on a C18 reversed phase column. The analysis was performed in a single run using a DAD detector coupled with an ESI-MS-MS source. Two Furocoumarins (bergapten and bergamottin) were detected and quantified simultaneously with the sixteen flavonoid components previously found in industrial bergamot juice. Full characterization of the Furocoumarins was performed by 1H NMR analysis on samples separated by means of preparative HPLC. The free-radical scavenging ability of cultivar juices was assessed by using DPPH radical. The data presented show that the “Femminello” cultivar, even though it is the least common of the three, is by far the richest in health-promoting bioactive compounds (both flavonoids and Furocoumarins). Given the range of applications of Furocoumarins, the preparative separation described herein is proposed as a simple ...
