The oranges were purchased from the local market of Bela. The orange peel and pulp were subjected to successive extraction with solvents in increasing order of their polarity viz. Acetone, hexane, methanol and distilled water. Orange peel and pulp powder was extracted separately by aqueous extraction. The phenolic content of these samples were studied according to the method described by Folin ...

The effects of odor exposure during the last 2 days of incubation and immediately after hatching on subsequent responses by chicks to that same scent were assessed. When tested with an orange-treated and an unscented container, chicks that had been previously exposed to orange odor more rapidly approached both containers than did control chicks and spent more time near them. In both conditions,...

Of the five species of white rot fungi evaluated for their ability to decolorize Amaranth, Remazol Black B, Remazol Orange, Remazol Brilliant Blue, Reactive Blue, and Tropaeolin O in agar plates, Bjerkandera sp. BOS55, Phanerochaete chrysosporium, and Trametes versicolor displayed the greatest extent of decoloration. In static aqueous culture, the three cultures formed fungal mats which did not...

Accelerated bleaching, photobleaching and mineralization of the non-biodegradable azo-dye, Orange II, was observed with oxone in solutions with Co2+-ions. The bleaching rate of Orange II in the dark was found to follow a first-order kinetics with respect to [Co2+] with a rate constant of 20 M−1 s−1. Fitting of the Orange II photobleaching experimental points in the presence of the Co2+/oxone re...

In the present study, activated bleaching earth was used as clay adsorbent for an investigation of the adsorbability and adsorption kinetics of acid dyes (i.e., acid orange 51, acid blue 9, and acid orange 10) with three different molecular sizes from aqueous solution at 25 degrees C in a batch adsorber. The rate of adsorption has been investigated under the most important process parameters (i...

Our objective was to examine the effect of orange juice and hesperetin on serum total antioxidant capacity (TAC), lipid peroxidation (MDA), uric acid and hepatic xanthine oxidase (XO) and xanthine dehydrogenase (XDH) activity in hyperuricemic rats. Experimentally hyperuricemia in rats was induced by intraperitoneal injection of potassium oxonate (250 mg/kg). Orange juice (5 ml/kg) and hespereti...

Objectives: The mechanism by which the mitochondrial K channel openers confer protection against ischemia / reperfusion injury is ATP debated. Evidence suggests that rather than solely being an end effector, opening of these channels may act by a trigger mechanism. We examined the effects of the mitochondrial K channel opener, diazoxide on parameters of mitochondrial function with specific refe...

A survey of the presence of Salmonella and Shigella in freshly squeezed orange juice and related samples was conducted in Guadalajara, Mexico. One hundred samples of freshly squeezed orange juice were collected from 49 street booths and 51 small food service establishments. In addition, 75 fresh orange samples, each consisting of five orange units, and 75 wiping cloths were collected from the s...

This study measures the influence of pH and polyaluminium chloride (PAC) dosage on the effectiveness of reactive dyes removal. Experiments were carried out for turquoise DG, red DB-8, orange OGR and black DN. The pH was changed from 3.5 to 7.0 and the dosages of PAC from 0.3 to 4.0 mg Al/mg dye. The degree of dyes removal depended on pH and dosage of coagulant. In the pH range from 4.0 to 5.5 t...
