Bioactive Flavonoids, Antioxidant Behaviour, and Cytoprotective Effects of Dried Grapefruit Peels (Citrus paradisi Macf.)
Grapefruit (Citrus paradisi Macf.) is an important cultivar of the Citrus genus which contains a number of nutrients beneficial to human health. The objective of the present study was to evaluate changes in bioactive flavonoids, antioxidant behaviour, and in vitro cytoprotective effect of processed white and pink peels after oven-drying (45°C-60°C) and freeze-drying treatments. Comparison with ...
متن کاملEffects of grapefruit (Citrus paradisi MACF) (Rutaceae) peel oil against developmental stages of Aedes aegypti (Diptera: Culicidae).
Laboratory bioassay of the essential oil extracted from the grapefruit (Citrus paradisi) peel by steam distillation was carried out against the developmental stages of the yellow fever vector Aedes aegypti to evaluate its toxicity, and ovicidal and larvicidal potency. Volatile oil components isolated and characterized by coupled gas chromatography/mass spectrometry included varying levels of mo...
متن کاملIrradiation and storage influence on bioactive components and quality of early and late season ‘Rio Red’ grapefruit (Citrus paradisi Macf.)
Irradiation as an alternative quarantine treatment has been under consideration by the International Consultative Group on Food Irradiation. This study was conducted on early and late season ‘Rio Red’ grapefruit to investigate the effects of harvest date, storage, and low dose irradiation on functional constituents, and quality. Fruit was treated with 0, 70, 200, 400 and 700 Gy and then stored ...
متن کاملPutative protease inhibitor gene discovery and transcript profiling during fruit development and leaf damage in grapefruit (Citrus paradisi Macf.).
Seven putative protease inhibitor (PPI) cDNAs, representing four protein families, were isolated from a grapefruit (Citrus paradisi Macf. Cv. Marsh) immature fruit flavedo cDNA library. Cloned open reading frames encoded proteins with similarity to, and protein signatures for: legume Kuntiz inhibitors (lkiL-1, lkiL-2, lkiL-3), potato trypsin inhibitor I (ptiIL-1), serpins (serpL-1), cystatins (...
متن کاملRutacridone-epoxide, a New Acridone Alkaloid from Rut a graveolens *
Several acridone alkaloids have been isolated from roots of Ruta graveolens (for summary see [1, 2]). One of the main alkaloids is rutacridone (1) which seems to be a precursor of several derivatives with hydroxyl or chlorine functions at the isopropyl moiety. As an intermediate an 18,19-epoxide of rutacridone could be postulated [1, 3] that has not yet been identified. Screening for antimicrob...
