This study was conducted to evaluate the antifungal activities of Cinnamomum zeylanicum and Origanum vulgare L. essential oil against Aspergillus flavus in culture media and tomato paste. 200 ppm of cinnamon and 500 ppm of oregano completely inhibited A. flavus growth in culture media, while in tomato paste 300 ppm of cinnamon and 200 ppm of oregano had the same effect. Test panel evaluations r...

In the present investigation, we examined the cytotoxic effect of methanolic extract from Origanum vulgare on HCT-116 and MDA-MB-231 cell line in vitro. In order to determine the cytotoxic effects we used an MTT viability assay. The results showed that cell growth is significantly lower in extract treated cells compared to untreated control. The effect of inhibition of cell growth was higher in...

introduction antibiotic feed additives have long been used as growth promoters in poultry nutrition. however, concern has been expressed about the potential development of antibiotic resistant bacteria (25). consequently, the animal feed industry, exposed to increasing consumer pressure to reduce the use of antibiotic growth promoters in poultry diets, has to find alternative feed additives. ma...

In this work the Origanum vulgare leaf extract was used to green synthesis of Ag nanoparticles (NPs) supported on Hazelnut shell as an environmentally benign support. The Ag NPs/Hazelnut shell as an effective catalyst was prepared through reduction of Ag+ ions using Origanum vulgare leaf extract as the reducing and capping agent and Ag NPs immobilization on Hazelnut shell surface in ...

objectives due to the known anti-oxidant and anti-diabetic effects of origanum majorana (om), this study was conducted to survey its effects on oxidative stress and histopathology of renal tissue among diabetic rats. materials and methods in this experimental investigation, 32 male rats, weighing 200 - 250 g, were divided into four groups: 1: control, 2: control receiving treatment with om, 3: ...

background and objectives: essential oils are very complex mixture of components and their composition may vary in different species or varieties or even within the same variety. origanum vulgare l. subsp. vulgare is one of the most distributed subspecies within the genus origanum and has been found to be a poor-oil, categorized in cymyl, bornane or sabinyl chemotypes with higher proportion of ...
