use of natural antimicrobial compounds extracted from plants such as cinnamon as preservative to extend the shelf life has gain much attention. in this study, we evaluated the antimicrobial activity and bio- preservative potential of the methanolic extract of cinnamomum verum bark and its oil against bacillus subtilis , pseudomonas aeruginosae and escherichia coli in ketchup sauce. in order to ...

the antioxidant properties of ruta graveolens l. were evaluated by two different methods; free radical scavenging using dpph and inhibition of lipid peroxidation by the ferric thiocyanate method. the ic50 value of the methanol extract in dpph inhibition was 200.5 μg/ml which was acceptable in comparison with bht (41.8 μg/ml). in thiocyanate method, the plant extract demonstrated activity as muc...

background & aim: considering that antioxidants are known as effective free radicals scavenger, it may be able to improve the in vitro oocyte maturation and the fetal quality. this study was designed to determine the effect of gundelia tournefortii leaves (gte) hydro-alcoholic extract as a source of antioxidant on in vitro oocyte maturation. experimental: germinal vasicle (gv) were recovere...

background & aim: oocytes in vitro maturation is an enormously promising technology for the treatment of infertility, yet its clinical application remains limited owing to poor success rates. therefore this study was designed to determine the effect of gundelia tournefortii root hydro alcoholic extract as a source of antioxidant on in vitro oocyte maturation. experimental: in this study, th...
