A study on shallow and parfrying in soybean oil as alternatives to deep frying and evaluation of stability of a formulated antioxidant administered to the oil was conducted. Potato wedges were deep, shallow and parfried in soybean oil for optimized time and temperature. A citric acid based antioxidant using BHT was formulated and administered to the oils before frying. The performance of antiox...

salvia genus is one of the largest genera of the lamiaceae family. its species have been used for a wide variety of disorders in the local traditional medicine systems. therefore, the genus has been the subject of several phytochemical and biological studies. the aim of the study was to identify the major antioxidant compound(s) from the methanol extract of salvia verticillata using activity-gu...

Phenolic compounds from Cressa cretica leaves were extracted using different solvents (water and ethanol 70%) during 3-24 h by immersion method and were determined according to the Folin-Ciocalteu method. The antioxidant activities of the extracts were investigated by 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical scavenging, ferric reduction activity potential and total antioxidant capacity ass...

Three different fractional (methanol, ethyl acetate and hexane) extracts from yuzu (Citrus junos Sieb ex Tanaka), hallabong [(C. unshiu Marcov × C. sinensis Osbeck) × C. reticulata Blanco] and orange (C. sinensis) were evaluated for their antioxidant activity and antiplatelet effects. 2,2-Diphenyl-1-Picrylhydrazyl (DPPH), cupric reducing antioxidant capacity (CUPRAC) and ferric-reducing antioxi...

The polyphenolic composition and antioxidant activity of the aerial parts of 18 medicinal or food plants of the Asteraceae family were studied. Five main caffeoyl derivatives were determined individually by HPLC and compared with levels determined by colorimetry for total dihydroxycinnamic derivatives and total phenolics. The aim of this study was to assess the contribution of these constituent...

objective:the present study was designed to evaluate the antioxidant, analgesic, and anti-inflammatory activities ofthe methanolic extract of piper betle leaves (mpbl). materials and methods: mpbl was evaluated for anti-inflammatory activity using carrageenan-induced hind paw edema model. analgesic activity of mpbl was evaluated by hot plate, writhing, and formalin tests. total phenolic and fla...

oxygen free radicals may be implicated in the pathogenesis of ischemia reperfusion damage. as the antioxidant effects of some species of pistacia have been reported, the protective effects of pistacia vera l. gum extract (0.1-0.5 g/kg) on oxidative damage following cerebral ischemia were studied in rats. ischemia was induced using four-vessel occlusion model and evaluated using measurement of m...

background: nowadays, there's a growing demand for the natural antioxidants due to the harmful effects of synthetic antioxidants. therefore, introduction of new natural antioxidants (especially those with plant origin) is very important. objective: the present study explores the chemical constitution and antioxidant activity of leaf extract of hyssopus officinalis l. and extract of aerial ...


 The reactivity of oxidant compounds that exceed the limits antioxidant protection ability can cause chain reactions which interference with system. Prevention is needed to neutralize oxidants, so exogenous antioxidants are needed. One example jamblang fruit (Syzygium cumini (L)) has high activity due its natural anthocyanin. purpose this study was determine optimal form yogurt addition e...

INTRODUCTION Oxidative stress (OS) is considered a significant contributor to male infertility. A number of laboratory techniques have been developed to evaluate oxidative stress in the semen. We review these tests and their current use. METHODS A literature review was performed utilizing the PubMed search engine for articles studying OS etiology and impact on male fertility, and the laborato...
