Juice prepared from lemon (Eureka), mandarin (Kinnow) and orange (Orlando) fruits cultivated in Saudi Arabia were analyzed for different physico-chemical properties, total phenolics, ascorbic acid and antiradical activities. Juices from lemon, mandarin and orange 8.97, 16.1 and 11.78% total soluble solids; 5.73, 1.37 and 1.69% titrable acidity; 79.21, 91.18 and 107.37 mg GAE/100mL total phenoli...

Purpose This study aims to demonstrate that orange-derived and lemon-derived systems can be used in continuous processes as efficient adsorbents the entrapment of some anionic cationic dyes textile dyeing wastewater effluents. Design/methodology/approach Physically chemically modified orange lemon mesocarps are natural for Basic Blue 3, Yellow 21, Red 18 Green 4 Acid 264, 49 337, all commonly i...

This work has studied the photoelectrochemical production of hydrogen peroxide and direct use produced material for degradation (decolorization) three common dyes: methylene blue, basic blue 41 acid orange 7. Hydrogen was in cathode compartment a photocatalytic fuel cell by atmospheric oxygen reduction. The operated with CdS-sensitized mesoporous titania photoanode simple carbon cloth carrying ...

Development of low-cost, high-performance catalysts for the effective degradation organic dyes is both fundamental and technological significance environmental remediation. Herein, FeN4-doped carbon nanotubes exhibit a remarkable catalytic activity towards acid orange 7 (AO7) in presence peroxymonosulfate (PMS). This accounted by abundant well-dispersed FeN4 sites appropriate adsorption energy....

We evaluated the in vitro antiproliferative and apoptotic potential of the ethyl acetate extract (EAE) of Peltophorum africanum, a member of the family Fabaceae (Sond) in order to validate its pharmacological use. Antiproliferation of human breast (MCF-7), colon (HT-29) and cervical (HeLa) cancer cell lines by EAE was investigated using the Cell Titer-Blue viability assay and the mechanism of a...

Carrots accumulate numerous carotenoids in the root, resulting different colors. Orange carrots are primarily high α- and β-carotene, while yellow packed with lutein. This study was designed to explore molecular mechanism underlying mutation involving lutein using a recently obtained root mutant carrot (ym) via mutagenesis of an orange wild type (wt). Microscopes were used observe variations hi...

based on the valuable antioxidant activity of citrus fruits, in present study the effect of ‎rootstock and the type of tissue on some fruit quality parameters including phenol, ‎flavonoid, antioxidant and the content of hesperidin and naringin of orange and mandarin ‎was studied. the experiment was conducted as a factorial design based on complete ‎randomized blocks with four replications. resu...

We have examined the ameba Dictyostelium discoideum for evidence of a discrete, prelysosomal, acidic receiving compartment in endocytosis. We observed in the cytoplasm abundant round vacuoles with diameters up to 2 microns that concentrated acridine orange by a process inhibited by 7-chloro-4-nitrobenzo-2-oxa-1,3-diazole (NBD-Cl). They were therefore taken to be acidic. The vacuoles were observ...

Green tea leaves have high contents of phenolic compounds which has strong antioxidant properties but can have bitter taste which makes it less useful in food applications. Encapsulation in nanoliposomes could mask undesirable taste of green teas components and protect them against processing and storage. The objective of this study was to: 1) produce and evaluate physical properties of green t...

Acid-etched graphitic carbon nitride (TGCN) nanosheets decorated with polyaniline (PANI) nanofibers for the adsorption and photocatalytic degradation of Methyl Orange (MO) Congo Red (CR) toxic textile dyes.
