Citrus fruits of industrial interest include lemons, oranges, mandarins, grapefruits, clementines, limes and other commercially minor ones. A huge amount agricultural waste is generated yearly all over the globe by citrus fruit industry. The wastes from these productions may be, however, great nutritional economic value for their chemical composition, due to abundance diverse functional compoun...

Antioxidant compounds and the antioxidative activities of new Israeli citrus fruit sweetie [(Oroblanco, pummelo-grapefruit hybrid (Citrus grandis C. paradisi)] were compared with the better-known white grapefruit. Total and free phenols were determined with the Folin–Ciocalteu reagent, phenolic acids (free, esters and glycosides) by HPLC analysis and anthocyanins spectrophotometrically. The ant...

Editorial Lown et al. (1) report a significant advance in describing a new mechanism by which ingested nutrients may change exposure to drug therapy. Grapefruit juice was reported to increase plasma concentrations of felodipine and nifedipine when the drug was concurrently administered with grapefruit juice (2). The potential clinical importance of such an interaction was noted when cyclosporin...

Kelly’s citrus thrips is one of the most common thrips species found in Cyprus citrus orchards. Kelly’s citrus thrips larvae were the sole insect stage causing feeding damage mainly on immature lemon and grapefruit fruits. Under Cyprus conditions Kelly’s citrus thrips adults prefer to concentrate mostly in the northern and eastern sides of both lemon and grapefruit canopies. The recorded mean n...

Carotenoids are the main pigments responsible of the colouration of Citrus fruits. The beta-cyclization of lycopene, catalysed by the lycopene beta-cyclases (beta-LCY), seems to be a key regulatory step of the carotenoid pathway. In the present study, two beta-LCYs from orange fruits (Citrus sinensis), named Csbeta-LCY1 and Csbeta-LCY2 have been isolated and the activity of the encoded proteins...

Many plant-derived, dietary polyphenols have been studied for their chemopreventive and chemotherapeutic properties against human cancers, including green tea polyphenols, genistein (found in soy), apigenin (celery, parsley), luteolin (broccoli), quercetin (onions), kaempferol (broccoli, grapefruits), curcumin (turmeric), etc. The more we understand their involved molecular mechanisms and cellu...

Citrus limonoids (CLs) are a group of highly oxygenated terpenoid secondary metabolites found mostly in the seeds, fruits and peel tissues of citrus fruits such as lemons, limes, oranges, pumellos, grapefruits, bergamots, and mandarins. Represented by limonin, the aglycones and glycosides of CLs have shown to display numerous pharmacological activities including anticancer, antimicrobial, antio...
