Citrus Flavonoids as Promising Phytochemicals Targeting Diabetes and Related Complications: A Systematic Review of In Vitro and In Vivo Studies.
    Nutrients, 2020, Sep-23, Volume: 12, Issue:10

    The consumption of plant-based food is important for health promotion, especially concerning the prevention and management of chronic diseases. Flavonoids are the main bioactive compounds in citrus fruits, with multiple beneficial effects, especially antidiabetic effects. We systematically review the potential antidiabetic action and molecular mechanisms of citrus flavonoids based on in vitro and in vivo studies. A search of the PubMed, EMBASE, Scopus, and Web of Science Core Collection databases for articles published since 2010 was carried out using the keywords citrus, flavonoid, and diabetes. All articles identified were analyzed, and data were extracted using a standardized form. The search identified 38 articles, which reported that 19 citrus flavonoids, including 8-prenylnaringenin, cosmosiin, didymin, diosmin, hesperetin, hesperidin, isosiennsetin, naringenin, naringin, neohesperidin, nobiletin, poncirin, quercetin, rhoifolin, rutin, sineesytin, sudachitin, tangeretin, and xanthohumol, have antidiabetic potential. These flavonoids regulated biomarkers of glycemic control, lipid profiles, renal function, hepatic enzymes, and antioxidant enzymes, and modulated signaling pathways related to glucose uptake and insulin sensitivity that are involved in the pathogenesis of diabetes and its related complications. Citrus flavonoids, therefore, are promising antidiabetic candidates, while their antidiabetic effects remain to be verified in forthcoming human studies.

Hydrolysis of flavanone glycosides by β-glucosidase from Pyrococcus furiosus and its application to the production of flavanone aglycones from citrus extracts.
    Journal of agricultural and food chemistry, 2013, Nov-27, Volume: 61, Issue:47

    The hydrolytic activity of the recombinant β-glucosidase from Pyrococcus furiosus for the flavanone glycoside hesperidin was optimal at pH 5.5 and 95 °C in the presence of 0.5% (v/v) dimethyl sulfoxide (DMSO) and 0.1% (w/v) Tween 40 with a half-life of 88 h, a Km of 1.6 mM, and a kcat of 68.4 1/s. The specific activity of the enzyme for flavonoid glycosides followed the order hesperidin > neohesperidin > naringin > narirutin > poncirin > diosmin > neoponcirin > rutin. The specific activity for flavanone was higher than that for flavone or flavonol. DMSO at 10% (v/v) was used to increase the solubility of flavanone glycosides as substrates. The enzyme completely converted flavanone glycosides (1 g/L) to flavanone aglycones and disaccharides via one-step reaction. The major flavanone in grapefruit peel, grapefruit pulp, or orange peel extract was naringin (47.5 mg/g), naringin (16.6 mg/g), or hesperidin (18.2 mg/g), respectively. β-Glucosidase from P. furiosus completely converted naringin and narirutin in 100% (w/v) grapefruit peel extract to 22.5 g/L naringenin after 12 h, with a productivity of 1.88 g L(-1) h(-1); naringin and narirutin in 100% (w/v) grapefruit pulp extract to 8.1 g/L naringenin after 9 h, with a productivity of 0.90 g L(-1) h(-1); and hesperidin in 100% (w/v) orange peel extract to 9.0 g/L hesperetin after 9 h, with a productivity of 1.00 g L(-1) h(-1). The conversion yields, concentrations, and productivities of flavanone aglycones in this study are the highest among those obtained from citrus extracts. Thus, this enzyme may be useful for the industrial hydrolysis of flavanone glycosides in citrus extracts.

Grapefruit (Citrus paradisi Macfad) phytochemicals composition is modulated by household processing techniques.
    Journal of food science, 2012, Volume: 77, Issue:9

    Grapefruits (Citrus paradisi Macfad) contain several phytochemicals known to have health maintaining properties. Due to the consumer's interest in obtaining high levels of these phytochemicals, it is important to understand the changes in their levels by common household processing techniques. Therefore, mature Texas "Rio Red" grapefruits were processed by some of the common household processing practices such as blending, juicing, and hand squeezing techniques and analyzed for their phytochemical content by high performance liquid chromatography (HPLC). Results suggest that grapefruit juice processed by blending had significantly (P < 0.05) higher levels of flavonoids (narirutin, naringin, hesperidin, neohesperidin, didymin, and poncirin) and limonin compared to juicing and hand squeezing. No significant variation in their content was noticed in the juice processed by juicing and hand squeezing. Ascorbic acid and citric acid were significantly (P < 0.05) higher in juice processed by juicing and blending, respectively. Furthermore, hand squeezed fruit juice had significantly higher contents of dihydroxybergamottin (DHB) than juice processed by juicing and blending. Bergamottin and 5-methoxy-7 gernoxycoumarin (5-M-7-GC) were significantly higher in blended juice compared to juicing and hand squeezing. Therefore, consuming grapefruit juice processed by blending may provide higher levels of health beneficial phytochemicals such as naringin, narirutin, and poncirin. In contrast, juice processed by hand squeezing and juicing provides lower levels of limonin, bergamottin, and 5-M-7-GC. These results suggest that, processing techniques significantly influence the levels of phytochemicals and blending is a better technique for obtaining higher levels of health beneficial phytochemicals from grapefruits. Practical Application:  Blending, squeezing, and juicing are common household processing techniques used for obtaining fresh grapefruit juice. Understanding the levels of health beneficial phytochemicals present in the juice processed by these techniques would enable the consumers to make a better choice to obtain high level of these compounds.

Protective effects of neohesperidin and poncirin isolated from the fruits of Poncirus trifoliata on potential gastric disease.
    Phytotherapy research : PTR, 2009, Volume: 23, Issue:12

    The effects of Poncirus trifoliata (P. trifoliata) (Ponciri Fructus, PF) extract and its constituents such as neohesperidin and poncirin on gastritis in rats and human gastric cancer cells were investigated. The PF 70% ethanol extracts (1 g) showed approximately 11.38% of acid-neutralizing capacities and cytotoxicity (IC50=85.39 microg/mL) against human AGS gastric cancer cells. In addition, neohesperidin exhibited antioxidant activity (IC50=22.31 microg/mL) in the 1,1-diphenyl-2-picryldydrazyl (DPPH) radical-scavenging assay. Neohesperidin (50 mg/kg) and poncirin (100 mg/kg) significantly inhibited 55.0% and 60.0% of HCl/ethanol-induced gastric lesions, respectively, and increased the mucus content. In pylorus ligated rats, neohesperidin (50 mg/kg) significantly decreased the volume of gastric secretion and gastric acid output, and increased the pH. From these results, it could be suggested that neohesperidin and poncirin isolated from PF may be useful for the treatment and/or protection of gastritis.
