Aflatoxin B1 (AFB1) is a highly toxic and carcinogenic metabolite produced by Aspergillus species on food and agricultural commodities. Inhibitory effects of essential oils of Ageratum conyzoides (mentrasto) and Origanum vulgare (oregano) on the mycelial growth and aflatoxin B1 production by Aspergillus flavus have been studied previously in culture medium. The aim of this study was to evaluate...

Horváthová J., Suhaj M., Polovka M., Brezová V., Šimko P. (2007): The influence of gamma-irradiation on the formation of free radicals and antioxidant status of oregano (Origanum vulgare L.). Czech J. Food Sci., 25: 131–143. The influence of various gamma-radiation dose absorptions on oregano (Origanum vulgare L.) solid samples was monitored by means of electron paramagnetic resonance (EPR) spe...

Abstract Background Research interest in plant essential oils has increased significantly due to their natural properties and consumer demand for safer methods of food preservation. Plants produce large amounts secondary metabolites, which have potential activity against fungal pathogens. This study aimed at screening antifungal effects on citrus Penicillium digitatum , morphological effect fin...

The chemical compositions, nutrients and mineral compositions of Origanum vulgare have been analyzed . results indicated that the inatial contents by using different solvent contens were flavonoids, glycoside ,sterols, alkaloids, phenolic compounds, tannins saponins quantitative , Flavonids, sterols, tannin, phenlic saponin alkaloids [(14.66±245.7 mg / 100gm), (197.71±11.89mg/100gm), (109.09±5....

objective: ionizing radiation produces free radicals which induce dna damage and cell death. origanum vulgare leaf extract (ovle) is a natural compound and its capability of scavenging free radicals and its antioxidant activity have been demonstrated by many researchers. in this study, using micronucleus assay, radioprotective effect of ovle against clastogenic and cytotoxic effect of gamma irr...
