title: Volatile and Flavonoid Composition of the Peel ofCitrus medicaL. var.CorsicanFruit for Quality Assessment of Its Liqueur.
abstract: The volatile and flavonoid compositions of the peel ofCitrus medicaL. var.Corsicanfruits cultivated in Corsica were studied according to the maturity of the citron fruits measured using growing degree-days. Quantitative variation with the stage of development of the fruit was observed using gas chromatography, gas chromatography-mass spectrometry, and liquid chromatography-mass spectrometry/mass spectrometry. Thirty volatile compounds were identified in the peel essential oil. Limonene and γ-terpinene were the major compounds. The volatile compositions of commercial citron liqueurs were also characterized by high amounts of monoterpene hydrocarbons with the same two major components. The main flavonoid components of citron fruits and derived liqueurs were rutin and neohesperidin. This chemical characterization can be used for quality assessment of food products fromC. medicavar.Corsican.
