Survey of Phenolic Compounds Produced in Citrus
Flavonoid Composition of Citrus

Citrumelo (Poncirus trifoliata × Citrus paradisi), which resulted from trifoliate orange × grapefruit hybridization, contains high levels of didymin, narirutin, and hesperidin. Poncerin, naringin (Albach and Redman 1969, Nishiura et al. 1971b, Kamiya et al. 1979, Anis and Aminuddin 1981) and neohesperidin (Horowitz and Gentili 1977) have been detected inP. trifoliata species. 'Sacaton' citrumelo contains mainly naringin and poncerin, along with narirutin, didymin, hesperidin, narirutin–4'–glucoside, neohesperidin, and naringin–4'–glucoside (Albach and Redman 1969). Since citrumelo cultivars examined in this study do not contain the same flavanones, the parental background of each must influence the flavanone composition of this hybrid. The flavone/ols, predominantly rhoifolin, were only detected in the leaves.
