Abstract:
ABSTRACT A suitable antioxidant for a poly(ethylene-co-propylene-co-5-ethylidene-2-norbornene) (EPDM) seal in tap water applications was determined with respect to volatilization and decomposition of the antioxidants. Seals were prepared by mixing EPDM with 1 phr antioxidant and other ingredients followed by vulcanizing the mixture at 433 K for 20 min. The resulting EPDM seals were immersed into chlorinated water to investigate accelerated degradation. The change in antioxidant content was measured by gas chromatography/mass spectroscopy (GC/MS) and high-performance liquid chromatography (HPLC

Natural antioxidants, especially those used in edible oil, are safer compared to chemically synthesized antioxidants. Therefore, research on natural antioxidants has become prevelant. Antioxidant peptides derived from food protein can effectively prevent oil oxidation. Protein hydrolyzation is widely applied for the production of antioxidant peptides in industry, and bioinformatics is employed nowadays to generate the desired peptide sequence. Furthermore, the mechanism of antioxidant peptides in the oil system is still controversial, which limits the further development of antioxidant peptide

Food raw materials and products contain inhibitors of oxidation reactions, both in the lipidic phase and the aqueous phase. The most important inhibitors are phenolic antioxidants. During food processing and storage, concentrations of antioxidants in the two phases reach an equilibrium. Phenolics react with lipidic free radicals, being converted into antioxidant free radicals, quinones, polymers and copolymers. Some degradation products possess an antioxidant activity, too.

Abstract. In this work, liquid extracts of banana, mango, and fruit palm peels recovered via supercritical fluid extraction (SFE) were used as natural antioxidants whose antioxidative effectiveness was compared with those of their synthetic antioxidant counterparts namely quercetin, gallic acid, and beta-carotene on improving biodiesel’s resistance to oxidation reaction. Blends of the two antioxidant types were tested in mono (single antioxidant) and binary (mixture of two antioxidants) dosages. The results show that a superior antioxidative effect was manifested by the natural antioxidants ex

Abstract:
Lipid oxidation is a series of reactions affecting food quality and shelf life since it impacts flavor, color, and nutrition. The food industry utilizes different antioxidants to retard oxidation. Interaction between antioxidants can improve the ability of the industry to protect foods if the antioxidant combination is synergistic. This research aims to determine the conditions where tocopherols and myricetin exhibit synergistic activity in bulk oils. Soybean oil was stripped to remove present endogenous antioxidants to better understand tocopherol-myricetin interaction. The oxidative stabilit

Abstract:
Thiosemicarbazones (TSCs) are well known for their diverse biological activities and wide-ranging applications. This study assessed the drug- likeness and antioxidant potential of previously synthesized steroidal TSCs with promising cytotoxicity. While all tested androstane TSCs are drug-like, they have poor water solubility, strong plasma protein binding ability, and low blood-brain barrier permeability. Mono-TSCs show better absorption parameters, but bis- TSCs are stronger antioxidants, with compound 4 being 4.5 times more active than ascorbic acid. All tested TSCs could be considered poten

Abstract:
Antioxidants are known to minimize oxidative stress by interacting with free radicals produced as a result of cell aerobic reactions. Oxidative stress has long been linked to many diseases, especially tumours. Therefore, antioxidants play a crucial role in the prevention or management of free radical-related diseases. However, most of these antioxidants have anticancer effects only if taken in large doses. Therefore, the combined use of antioxidants with chemotherapeutic agents is an attractive strategy to combat various tumours. This article focuses on the antioxidant effect of emoxypine. The

Abstract:
This research investigates the chemical composition, total phenolic and flavonoid content, and antioxidant activity of acetone, methanol, and ethanol extracts of the lichen Umbilicaria grisea, and its major secondary metabolite, gyrophoric acid. The extracts were analyzed using high-performance liquid chromatography (HPLC-UV) and spectrophotometric assays. The results showed significant levels of phenolic compounds and flavonoids, which contribute to the lichen’s antioxidant potential. The antioxidant activity was evaluated using in vitro assays such as DPPH and ABTS radical scavenging activit

Abstract:
The objective of this research project was to evaluate the involvement of antioxidant enzymes and genes in the resistance mechanism to postharvest superficial scald development using two primary systems: 1. Resistant and susceptible progenies of an apple cross between a scald resistant crab apple, ‘White Angel’ and a scald susceptible cultivar, ‘Rome Beauty’; 2. Heat-treatment of ‘Granny Smith’, which is known to reduce scald development in this cultivar. In 2002 we asked for, and received (October 14), permission to revise our initial objectives.

Abstract:
Several grape varieties and red wines were found to contain large concentration of phenolic compounds which work as antioxidant in-vitro and in-vivo. Wastes from wine production contain antioxidants in large amounts, between 2-6% on dry material basis. Red wines but also white wines were found to prevent lipid peroxidation of turkey muscle tissues stored at 5oC. The antioxidant reaction of flavonoids found in red wines against lipid peroxidation were found to depend on the structure of the molecule. Red wine flavonoids containing an orthodihydroxy structure around the B ring were found highly
