Flavonoids in Citrus Hybrids

Flavanone and Nootkatone Levels in Different Varieties of Grapefruit and Pummelo

“…These compounds not only play an important physiological and ecological role but are also of commercial interest. For example, it is known that grapefruit and pummelo accumulate naringin as flavonone glycoside in their fruit, leaves, and juice, and, to a lesser extent, they also produce narirutin, prunin, hesperidin, and neohesperidin (Albach and Redman, 1969;Albach et al, 1981;Albach and Wutscher, 1988;Berhow andVandercook, 1989, 1991;Del Rio and Ortufio, 1994;Jourdan et al, 1985;Kamiya et al, 1979;Kanes et al, 1993;Robertson and Nisperos, 1983;Rouseff et al, 1987;Shaw et al, 1991;Sinclair, 1972).…”

Flavonoid Composition of Fruit Tissues of Citrus Species

“…[6][7][8][9] These methods are effective for the separation and identification of flavonoids, but of limited quantitative value. The introduction of the HPLC technique has led to better resolution and more precise quantification.…”

Phytochemical Diversity in the Order Rutales

“…The distribution of these glycosides in Citrus hybrids has been reviewed. 34 Some genera within the Rutaceae (Citrus and its allies, Murraya, Merrillia, Micromelum, Melicope) produce poly-oxygenated flavanones, flavones and flavonols. 35 In most cases these compounds are highly methylated, the most extreme example being exoticin (3,5,6,7,8,3',4',5'-octamethoxyflavone) from Murraya exotica.…”
