The aerial parts of Salvia multicaulis, S. sclarea and S. verticillata were collected at full flowering stage. The essential oils were isolated by hydrodistillation and analyzed by combination of capillary GC and GC-MS. The in vitro antimicrobial activity of the essential oils were studied against eight Gram-positive and Gram-negative bacteria (Bacillus subtilis, Bacillus pumulis, Enterococcus ...

Commiphora molmol oleoresin (Family Burseraceae) is traditionally used for treatment of many ailments such as ulcers, abscesses and wounds. The aim of this study was to evaluate the antimicrobial and antioxidant activities of C. molmol extracts in vitro (essential oils and ethanol extract). The antimicrobial activities of extracts were evaluated by disc diffusion and micro-broth dilution assays...

This study evaluated the in vitro antibacterial activity of essential oils from Lippia graveolens (Mexican oregano), Origanum vulgaris (oregano), Thymus vulgaris (thyme), Rosmarinus officinalis (rosemary), Cymbopogon nardus (citronella), Cymbopogon citratus (lemongrass), and Eucalyptus citriodora (eucalyptus) against Escherichia coli (n = 22) strains isolated from Alouatta spp. feces. Minimum i...

The chemical composition and antimicrobial activity of essential oils obtained from three Brazilian plant species-leaves and branches of Eremanthus erythropappus (Asteraceae), leaves of Plectranthus barbatus, and leaves of P. amboinicus (Lamiaceae)-were determined. Analysis by GC/MS and determination of Kovats indexes both indicated δ-elemene (leaves-42.61% and branches-23.41%) as well as (-)-α...

Essential oils are mixtures of volatile, lipophilic compounds originating from plants. Some essential oils have useful biological activities including antimicrobial, spasmolytic, antiplasmodial, and insect-repelling activities. In this study, we tested the antimicrobial activity of essential oil prepared from the aromatic plant, Cymbopogon citrates, against three important plant pathogenic and ...

objective: the growing resistance of different bacteria to antibiotic chemical drugs have become the global issue. this investigation is the first study of the antimicrobial activity of the essential oil of flowering aerial parts of vaccinium arctostaphylos. the current research was conducted to evaluate the antibacterial effects of essential oils and hydroalcoholic extract  extracted from aeri...

abstract       background and objective: the aim of this study was to determine the chemical composition, antibacterial and antifungal effects of thymus vulgaris and cuminum cyminum essential oils against foodborne pathogens and candida species in vitro.       methods: the essential oils were extracted from the aerial parts of thymus vulgaris and dried cuminum cyminum seeds using a clevenger ap...

Seventeen microbial species including 10 fungal taxa, two yeasts and five bacteria, were isolated from freshly prepared orange, guava and banana juices kept in open bottles at room temperature for 7 days. Eight different essential oils, from local herbs, were tested for their antimicrobial activity against these test organisms. The essential oils of Cymbopogon citratus, Ocimum basilicum and Ori...

Peganum harmala L., also known as Syrian rue or Pègano, is a herbaceous plant belonging to the Zygohpyllaceae family, and is widely used in traditional medicine. The chemical composition of essential oils of P. harmala seeds from five different regions of Northern Africa (Algeria, Egypt, Libya, Morocco and Tunisia) was studied by GC and GC-MS analyses. A total of 105 compounds were identified, ...
