Raisins (Vitis vinifera L.) are dried grapes largely consumed as important source of nutrients and polyphenols. Several studies report health benefits of raisins, including anti-inflammatory and antioxidant properties, whereas the anti-inflammatory activity at gastric level of the hydro-alcoholic extracts, which are mostly used for food supplements preparation, was not reported until now. The a...

Liver injury was induced in female rats using tamoxifen (TAM). Grape seeds (Vitis vinifera) extract (GSE), black seed (Nigella sativa) extract (NSE), curcumin (CUR) or silymarin (SYL) were orally administered to TAM-intoxicated rats. Liver histopathology of TAM-intoxicated:rats showed pathological changes. TAM-intoxication elicited declines in liver antioxidant enzymes levels (glutathione perox...

the effect of different solvent systems on the extraction of antioxidant and anti radical agents of grape seed was studied. for this purpose 6 different solvent systems with similar polarity and different selectivity were used to prepare grape seed extract. extraction efficiency, reducing activity, radical scavenging property and the effect of each extract on the increase of thermal resistance ...

abstract   background: the compounds which contain nitrogen entering the environment can cause some problems, such as eutrophication for water resources and potential risk for human health because of methemoglobinemia and cancer. biological techniques are effective in removing nitrate. the aim of this study was to remove nitrate from groundwater using denitrification. the main objectives of thi...

persian oak (quercus brantii lindl., the fagaceae family) is a medicinal plant which seed flour is used to treat inflammatory and gastric ulcers by the tribes in southwestern iran. the current study was done to evaluate the effect of hydro-alcoholic extract of q. brantii seed flour for treatment of gastric ulcers induced by ethanol in wistar rats. the hydro-alcoholic extract of q. brantii was t...

objective: oxidative stress plays an important role in the development of diabetic complications including metabolic abnormality-induced diabetic micro-vascular and macro-vascular complications. urtica dioica l. (u. dioica) has been traditionally used in iranian medicine as an herbal remedy for hypoglycemic or due to its anti-inflammatory properties. the aim of the present study was to evaluate...

Background and Aim: There are some rich sources of antifungals in medicinal herbs. They have general acceptance due to their low cost and insignificant side effects. The efficacy of Peganum harmala (P. harmala) extract against Candida species was investigated in this study.    Materials and Methods: In this in vitro study, we used the maceration technique to obtain P. harmala aqueous and al...

Objectives Reactive oxygen species (ROS)-produced oxidative disorders were involved at the pathophysiology of many inflammatory processes via the generation of pro-inflammatory cytokines and antioxidant defense system suppression. Although herbal antioxidants as mono-therapy relief many inflammatory diseases including, autoimmunity rheumatoid arthritis, but as combination therapy with other pro...

this study has been done to survey of solvent system effect on extraction of grape seed extract and its antimicrobial properties. for this purpose, grape seed extracts were extracted with six different solvent systems. minimum bactericidal concentration (mbc) of extract on six spoilage and food-born pathogens was determined. the results indicated that mbc of different extracts have no significa...
