“…That is the case of the pera variety (Citrus sinensis Osbeck) whose concentration of hesperidin found in the orange juice was 0.269 mg•g −1 [28] which is lower than the amount found in the respective peel that was 8.61 mg•g −1…”

“…The bahia variety orange juice presented 0.427 mg•g −1 of this substance [28] while the concentration in the orange peels was 41.17 mg•g −1 (LBD, Table 1). The same situation was observed in the lima variety juice which presented 0.223 mg•g −1 of hesperidin and its peel contained 28.30 mg•g −1 (LLD, Table 1).…”

The flavonoid content in orange peels of different Brazilian citrus varieties such as bahia, lima, lima-of-persian, morcote, pera, ponkan, seleta, cravo, kinkan and pomelo was assessed. Industry processing juice wastes such as bagasse, bagasse residues, animal feeding bagasse, pulp WEUE and CORE-wash were also analyzed. The HPLC analysis indicates that the most abundant flavonoids found in these Brazilian citrus peels are hesperidin and naringin. The solvents used are selective for flavonoid extraction, and depending on their polarity, glycoside or aglycone flavonoids are extracted. The use of multivariate analysis shows that DMSO is the best solvent to extract glycosides flavanones while hexane displays high selectivity in the extraction of polymethoxylated flavones. The flavonoids present in the orange wastes, obtained at different stages of the industrial processing, are qualitative and quantitatively different. The identification and quantification of the flavonoid composition in each Brazilian citrus variety were evaluated and allowed the selection of the best solvent for the extraction of each specific class of flavonoids. These compounds were found to be more abundant in the fruit peels than in their juices, revealing their great industrial potential. The residual portion of the processing juices is also rich in flavonoids, depending on the processing step.

“…The production of fresh single‐strength and concentrated orange juices leaves a residue of pulp that may be extracted with water to produce pulp‐wash. Pulp‐wash, which has appreciably higher concentrations of hesperidin and narirutin than the juice, can be used in drink manufacture, but its use to adulterate fresh juice is prohibited in many countries 15. Citrus composition varies with place of cultivation, rootstock, cultivar and maturity in addition to the factors discussed above.…”

Flavanones, chalcones and dihydrochalcones - nature, occurrence and dietary burden

This paper reviews the occurrence in foods of flavanones, chalcones and dihydrochalcones. The major dietary sources of flavanones and dihydrochalcones are citrus fruits and apples respectively. These compounds may make a greater contribution to the total daily intake of flavonoids than the more extensively studied flavonols. There are no data for plasma or tissue levels, but both endogenous and gut flora metabolites of both classes of compound are found in urine. For these reasons, these compounds deserve greater attention in epidemiological studies. © 2000 Society of Chemical Industry

“…Sweet orange juice from different origins has been analyzed for flavonoids qualitatively and quantitatively by HPLC and it was characterized mainly by the presence of three groups of flavonoids: flavanones, flavones and flavonols (Mouly et al, 1994(Mouly et al, , 1998Sendra et al, 1988;Pupin et al, 1998).…”

HPLC-diode array detection-electrospray ionization mass spectrometry was used to determine qualitatively and quantitatively the flavonoid content of several fractions and residues of extracts of Greek navel sweet orange peel (Citrus sinensis) from the region of southern Greece (Leonidi-Tripoli). The main groups of flavonoids found according to HPLC retention times, spectral data and literature references were polymethoxylated flavones, C-glycosylated flavones, O-glycosylated flavones, O-glycosylated flavanones, flavonols and phenolic acids and their derivatives. The ethyl acetate fraction which has been shown in previous work to possess the best radical scavenging activity among the others was found to contain C-glycosylated flavones, polymethoxylated flavones, O-glycosylated flavones, O-glycosylated flavanones, two phenolic acid derivatives and two unknown compounds, all in low concentrations. The group of C-glycosylated flavones was reported for the first time in the peel of Navel sweet orange. The C-glycosylated flavones found according to their spectral characteristics and literature were 6-C-beta-glucosyldiosmin, 6,8-di-C-glucopyranosylapigenin, 6,8-di-C-beta-glucosyldiosmin and two unknown. The results suggest that the ethyl acetate fraction of navel Citrus sinensis peel consists of significant antioxidant compounds and can be used as a food additive of natural origin or a pharmaceutical supplement using as a source of peel the byproducts of the orange juice industry.
