Natural antioxidants compounds are present in leaf, rhizome, stem, fruits, vegetables, tea etc. They are recognized as important compounds in conferring stability against oxidation in vitro. Natural antioxidant compounds can be classified into Exogenous antioxidants and Endogenous antioxidants, Enzymatic and NonEnzymatic antioxidants. Naturally occurring antioxidants compounds are carotenoids, ...

The present study mainly focused on quantification and comparison of non enzymatic antioxidants from pulp extracts of nine varieties of banana viz Kadali, Karpooravalli, Monthan, Nenthiran, Pachainadan, Poovan, Rasthali, Robusta and Sevvazhai. The non enzymatic antioxidants such as total reduced glutathione, vitamin A, vitamin C, vitamin E were quantified from banana pulp extract. The data obta...

Methanol is primarily metabolized by oxidation to formaldehyde and then to formate. These processes are accompanied by formation of superoxide anion and hydrogen peroxide. This paper reports data on the effect of methanol on antioxidant status and lipid peroxidation in lymphoid organs such as the spleen, thymus, lymph nodes and bone marrow of rats. Male Wistar albino rats were intoxicated with ...

Piper species, commonly used in diet and traditional medicine were assessed for their antioxidant potential. Catalase activity was predominated in Piper longum, followed by Piper cubeba, green pepper, Piper brachystachyum and Piper nigrum. P. nigrum was richest in glutathione peroxidase and glucose-6-phosphate dehydrogenase, green pepper was richest in peroxidase and vitamin C while vitamin E w...

Objectives: The study aims to estimate the changes in the serum levels of lipid peroxidation product malondialdehyde (MDA), non-enzymatic antioxidants: vitamin A, E and C and erythrocyte enzymatic antioxidants: superoxide dismutase (SOD) and catalase(CAT) in chronic alcoholic liver disease. Background: Alcohol consumption accounts for about 50% of patients death from end stage liver disease in ...

in vitro maturation (ivm) is emerging as a popular technology at the forefront of fertility treatment and preservation. however, standard in vitro culture conditions usually increase reactive oxygen species (ros), which have been implicated as one of the major causes for reduced embryonic developmental competence. it is well-known that higher than physiological levels of ros triggers granulosa ...

Microalgae have become an attractive natural source of a diverse range biomolecules, including enzymatic and non-enzymatic antioxidants; nevertheless, economically sustainable production such compounds from microalgae biomass is still challenging. The main hurdles are: (a) increasing yield; (b) achieving optimal cultivation conditions; (c) energy-efficient cost-effective downstream processing (...

Milk contains plenty of enzymatic and non-enzymatic antioxidant components that probably account for the vital antioxidant protection of the infants at early stages of life against the development of complications induced by oxygen free radicals. Indigenous milk enzymes play a key role in regulating lactogenesis, including active involution of mammary gland. Moreover, they are essential constit...
