Introduction: Hydrogen peroxide (H2O2) is a biologically important, non-radical reactive oxygen species (ROS) that can influence several cellular processes. Ability of anti-oxidants to scavenge H2O2 can be measured by several methods but all the methods are suffering from several lacunae due to poor reproducibility, lack of specificity, inaccuracy, high cost etc. Objective: The present study ai...

To evaluate the free radical scavenging activity of flavonoids containing extracts of Stevia leaf. Alcoholic. Successive butanolic and alcoholic extracts of leaves were examined for free radical scavenging activity using BHT (tert-butylhydroxytolune) as a positive control by in vitro models. Successive alcoholic extract showed remarkable free radical scavenging activity. The IC(50) was found to...

(c. annuum) are an excellent source of vitamins a and c as well as phenolic compounds, which are important antioxidant components that may reduce the risk of diseases. the objective of this study was to evaluate their antioxidant activity under various temperatures. materials and methods: to compare the antioxidant activity in various temperatures (2...

Purpose: To evaluate protein hydrolysates and membrane ultrafiltration fractions of blue-spotted stingray for metal chelating and radical scavenging activities, as well as protection against oxidative protein damage. Methods: Stingray protein isolates were hydrolysed with alcalase, papain and trypsin for 3 h. Alcalase hydrolysate was fractionated by membrane ultrafiltration to yield < 3, 3 10 a...

Apitherapy has become the focus of attention as a form of folk and preventive medicine for treating certain conditions and diseases as well as promoting overall health and well-being. In apitherapy, honey is the therapeutic agent used for dressing surgical wounds, burns or skin ulcers, as well as for dyspepsia, peptic ulcer, etc., because of its antioxidant activity. Therefore, it is important ...

A free radical scavenging activity is an important property of natural dietary compounds, caffeine and caffeic acid compound widely present in many fruits, vegetables and coffee. The present study focused on determining the antioxidant activity of caffeine, caffeic acid and (caffeine + caffeic acid) through invitro antioxidant experiments. Invitro lipid peroxidtion, 1,1diphenyl-2-picryl-hydrazy...

Averrhoa bilimbi L. belongs to family Oxalidaceae. Traditionally, people use this plant (root, bark, leaves and fruits) for treating several illnesses include itches, boils, syphilis, whooping cough, hypertension, fever and inflammation. The aim of the study was to evaluate the nitric oxide (NO) scavenging activity and GC-MS analysis of A. bilimbi L. fruit extract. Averrhoa bilimbi L. fruits we...

Terminalia bellirica Roxb belongs to the family Combretaceae, is distributed throughout the deciduous forests of India. The petroleum ether, chloroform, ethanol and aqueous extracts of the bark of Terminalia bellirica were screened for free radical scavenging activity against DPPH, ABTS, superoxide, nitric oxide, hydroxyl and hydrogen peroxide radicals. The scavenging activity was found to be d...

the present study was carried out to determine the free radical scavenging properties of some plants, found in malaysia. the air-dried leaves of each plant (20 g) were soaked in distilled water (1:20; w/v) for 72 h at room temperature. collected supernatants were tested for free radical scavenging activity against the dpph and superoxide anion radical scavenging assays. all extracts were found ...
