safety and beneficence of farm animal nutrition plays a great role in their healthy life which in turn have impact on human nutrition via diary or meat products. assessing safety and beneficence of vicia varibilis freyn and sint. which is chosen intrinsically by domesticated animals of kohgiluyehand boyerahmad iranis the aim of the present work. our results not only show no cytotoxic activity i...

free radicals play an important role in pathological processes such as aging and developing cancer; hence, natural products inhibit free radical production, and can play an important role in preventing diseases. we aimed to evaluate the scavenging activity of free radicals, reducing power, inhibition of lipid peroxidation and malondialdehyde (mda) formation, and the antioxidant composition of r...

The aim of this study was to assess the ability of different wines – a sweet red, a dry red, a sweet white, and a dry white – to scavenge the stable 1,1’-diphenyl-2-picryl-hydrazyl radical (DPPH.) and to determine their phenolic composition. Both red wines contained, apart from anthocyanins, also higher concentration of total phenolics, tartaric esters, and flavonols than the two white wines. A...

An ethanol extract of the stem of Opuntia ficus-indica var. saboten (OFS) was assessed to determine the mechanism(s) of its antioxidant activity. The ethanol extract exhibited a concentration-dependent inhibition of linoleic acid oxidation in a thiocyanate assay system. In addition, the OFS extract showed dose-dependent free-radical scavenging activity, including DPPH radicals, superoxide anion...

BACKGROUND Phenolic compounds are widely distributed in plant kingdom and constitute one of the most important classes of natural and synthetic antioxidants. In the present study fifty one natural and synthetic structurally variant phenolic, enolic and anilinic compounds were examined as antioxidants and radical scavengers against DPPH, hydroxyl and peroxyl radicals. The structural diversity of...

BACKGROUND Cellular damage caused by reactive oxygen species (ROS) has been implicated in several diseases, and hence natural antioxidants have significant importance in human health. The present study was carried out to evaluate the in vitro antioxidant and reactive oxygen species scavenging activities of Terminalia chebula, Terminalia belerica and Emblica officinalis fruit extracts. METHODS...

objectives: consumption of fruits, such as plums and prunes, is useful in treating blood circulation disorder, measles, digestive disorder, and prevention of cancer, diabetes, and obesity. the paper presents a description of antioxidant and antiradical capacity of plum (prunus domestica l.) in both fresh and dried samples. materials and methods: samples were mixed with methanol and ethanol (as ...

Due to the excellent antioxidant capacity of proanthocyanidins, combined with mechanism anthocyanins, it inspired us study proanthocyanidins and their complexes. In this article, we conducted tests on proanthocyanidin-bovine serum albumin procyanidin-metal complexes, using DPPH ABTS methods determine procyanidins The results show that compared proanthocyanidin complex has a certain degree impro...

background & aim: when the level of free radicals is increased and also when both the enzymatic systems and low molecular antioxidants are not sufficient to protect the organism, it seems necessary to get antioxidants from external sources. this study aimed to evaluate the antioxidant potential of different parts of catharantus roseus experimental: the antioxidant potential of ethanol extra...
