introduction this study was conducted to evaluate the effect of essential oils of oregano, sweet orange and cumin on chemical composition, parameters of gas production capacity, aerobic stability and degradability of dry matter corn silage carried. secondary metabolites such as essential oils have antimicrobial properties that by adjusting ruminal fermentation in ruminants to improve the use of...

This study was conducted to determine the insecticidal activity of essential oils from oregano, Origanum onites L. (Lamiales: Lamiaceae), savory, Satureja thymbra L. (Lamiales: Lamiaceae), and myrtle, Myrtus communis L. (Rosales: Myrtaceae) against three stored-product insects. Essential oils from three species of plants were obtained by Clevenger-type water distillation. The major compounds in...

Materials and methods: One hundred eighty 21-day-old Yorkshire-Landrace pigs were randomly assigned to five treatments. Treatments were the unsupplemented, unmedicated basal diet (Control) and the basal diet supplemented with either 4.41 g per tonne flavomycin (Huvepharma, Inc, Peachtree City, Georgia; Flavomycin), 1.5 kg per tonne oregano oil (Van Beek Scientific, Orange City, Iowa; Oregano), ...

O regano is an herb that has been cultivated for centuries in the Mediterranean region, although now it can be found in most continents. The name oregano translates roughly into ‘‘mountain joy,’’ which explains in part its association for ancient Greeks and Romans with joy and happiness. Actually there is not simply one ‘‘oregano,’’ but rather several species that may contribute to the oregano ...

Introduction Origanum vulgare (the scientific name of oregano) has been studied in depth due to a number of interesting and exciting potential clinical uses. There is also an ongoing interest in a number of industries to replace synthetic chemicals with natural products that have similar properties. Many bioactive compounds can be found in aromatic plants, and there are a number of different wa...

Bioactivity of oregano methanolic extracts and essential oils is well known. Nonetheless, reports using aqueous extracts are scarce, mainly decoction or infusion preparations used for therapeutic applications. Herein, the antioxidant and antibacterial activities, and phenolic compounds of the infusion, decoction and hydroalcoholic extract of oregano were evaluated and compared. The antioxidant ...

Although the majority of patients with acute Lyme disease can be cured with the standard 2-4 week antibiotic treatment, about 10-20% of patients continue suffering from chronic symptoms described as posttreatment Lyme disease syndrome. While the cause for this is debated, one possibility is that persister bacteria are not killed by the current Lyme antibiotics and remain active in the system. I...

A gas liquid chromatographic analysis of the essential oils from four new Greek Oregano clones revealed that carvacrol was the predominant constituent in all clones, representing extremely high percentages of the oils (from 79.5% in a clone named Athos to 93% in a clone named Olympus). The thymol content ranged from 0.04 to 0.55 percent among the tested clones. Phenols (carvacrol and thymol) an...

The effects of an alginate-based edible coating containing natural antioxidants (rosemary and oregano essential oils) on lipid oxidation, color preservation, water losses, texture and pH of beef steaks during 14 days of display were studied. The essential oil, edible coating and beef antioxidant activities, and beef consumer acceptability were also investigated. The edible coatings decreased li...
