The volatile oils of black pepper [Piper nigrum L. (Piperaceae)], clove [Syzygium aromaticum (L.) Merr. & Perry (Myrtaceae)], geranium [Pelargonium graveolens L'Herit (Geraniaceae)], nutmeg [Myristica fragrans Houtt. (Myristicaceae), oregano [Origanum vulgare ssp. hirtum (Link) Letsw. (Lamiaceae)] and thyme [Thymus vulgaris L. (Lamiaceae)] were assessed for antibacterial activity against 25 dif...

The sensory, microbiological and physicochemical attributes of fresh meat stored at 5 and 15 degrees C were affected by the combined effect of volatile compounds of oregano essential oil and modified atmosphere packaging conditions (40% CO2/30% N2/30% O2, 100% CO2, 80% CO2/20% air, vacuum pack and air). It was found that the extension of shelf life of meat samples depended on the packaging cond...

Background: Origanum vulgare is used in traditional medicine for antimicrobial, anti-inflammatory and antioxidant activities. Objectives: The present study was designed to investigate the protective effects of O. vulgare leaves extract on experimentally induced intestinal ischemia/reperfusion (I/R) injury in rats. Materials and Methods: In this experimental study, 24 male Wistar albino rats ran...

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...

In this work 1H NMR metabolomics has been employed for quality control of oregano samples. data and morphological analysis (MA) were combined by PCA, obtaining a model able to individuate non-marketable samples, distinguish between the two marketable species (Origanum vulgare O. onites) on basis their metabolomic profile. Through approach distinctive biomarkers found, namely apigenin p-cymene o...

The antibacterial activity of essential oils extracted from Origanum compactum, Thymus capitatus, Foeniculum vulgare, and Rosmarinus officinalis was assessed with the well diffusion method a microbroth dilution assay against E. coli isolated carcasses rabbits. chemical composition these also determined by gas chromatography coupled mass spectrometry (GC/MS). results this study indicate that hig...

A method for the extraction of valuable compounds from plants and flowers (viz. laurel, rosemary, thyme, oregano and tuberose) is proposed. The dynamic approach allows go-and-backward circulation of the extractant (ethanol) through the solid sample subjected to the action of an ultrasound probe (thus reducing sample amount and avoiding overpressure). A multivariate optimisation study and applic...

The addition of sachets or pads containing volatile antimicrobial agents into packages has been the most successful commercial application of antimicrobials to packaging. In this study, the effect of oregano (Origanum onites) essential oil on the extension of shelf life of overwrap packed fresh chicken drumsticks was investigated. Meat exudate absorbent pads were sprayed with 5 mL of oregano es...

Alginate films with different degrees of crosslinking obtained by internal and external gelation method and alginate films incorporated with oregano essential oil were prepared. The effect of mechanism of gelation and the incorporation of oregano essential oil on their optical, mechanical, antibacterial, microstructural and water vapor barrier properties were evaluated. The films subjected to e...

As a result of antibiotic resistance in human pathogenic bacteria, alternatives for Antibiotic Growth Promoters (AGP) have been developed in recent years. Herbs and botanicals can be seen as such an alternative (WENK, 2003). Essential oils derived from different plants have been tested over the years to identify their effects on animal performance. Essential oil extracts from Oregano, with its ...
