چکیده

An HPLC analysis was performed on the concentrations of flavonoids in 42 species and cultivars of the Citrus genus and those of two Fortunella and one Poncirus species according to the classification system established by Tanaka. The composition of 8 flavanones and 9 flavone/ols for these species was determined in the albedo, flavedo, segment epidermis and juice vesicle tissues, and those in the fruit and peel tissues were calculated from the composition data of the tissues. A principal component analysis showed that such neohesperidosyl flavonoids as neoeriocitrin, naringin, neohesperidin, and rhoifolin had large factor loading values in the first principal component for each tissue. The flavonoid composition of citrus fruits was approximately the same within each section of Tanaka's system, except for the species in the Aurantium section and those with a peculiar flavonoid composition such as Bergamot (C. bergamia), Marsh grapefruit (C. paradisi), Sour orange (C. aurantium), and Shunkokan (C. shunkokan). The Aurantium section included both naringin-rich and hesperidin-rich species.

Effects of Citrus Fruit Juices on P-glycoprotein-mediated Transport in L-MDR1 Cells and CYP3A4-mediated Metabolism in Human Intestinal Microsomes

Fruit juice-drug interactions involving drug transporters and metabolic enzymes have been studied with various citrus fruit juices. The collective data led us to hypothesize that the modulating activity of citrus fruit juices on cellular transport and metabolic pathways is dependent on the dominant flavonoid pattern and taxonomy of the citrus fruits. This hypothesis has important implications g...

Estimated dietary flavonoid intake and major food sources of U.S. adults.

Estimating flavonoid intake is a first step toward documenting the protective effects of flavonoids against risk of chronic diseases. Although flavonoids are important dietary sources of antioxidants, insufficient data on the comprehensive food composition of flavonoids have delayed the assessment of dietary intake in a population. We aimed to estimate the dietary flavonoid intake in U.S. adult...
