In this study, extracts and essential oils of Black and Red pepper and Thyme were tested for antibacterial activity against Escherichia coli O157:H7 andStaphylococcus aureus. Black and Red pepper and Thyme were provided from Iranian agricultural researches center. 2 g of each plant powder was added to 10 cc ethanol 96°. After 24 h, the crude extract was separated as an alcoholic extract and con...

In the present investigation antimicrobial activity of six different plant essential oils i.e., citrus (Citrus lemon), olive (Olea europaea), ajwain (Trachiyspirum ammi), almond (Amygdalus communis), Bavchi (Psoralea corylifolia) and neem (Azadirachta indica) oils have been evaluated. After bioassays, most of the essential oils were found susceptible to both Gram-positive bacteria such as Lacto...

Essential oils obtained from the NR (normal roots) and HR (hairy roots) of the medicinal plant Leonurus sibiricus root were used in this study. The essential oil compositions were detected by GC-MS. Eighty-five components were identified in total. Seventy components were identified for NR essential oil. The major constituents in NR essential oil were β-selinene (9.9%), selina-4,7-diene (9.7%), ...

BACKGROUND A number of bio-active secondary metabolites have been identified and reported for several Hypericum species. Many studies have reported the potential use of the plant extracts against several pathogens. However, Hypericum triquetrifolium is one of the least studied species for its antimicrobial activity. The aim of the present study was to evaluate the cytotoxic effect of the essent...

ABSTRACT: Essential oils are commonly used to treat minor health problems. In this study the chemical compositions of Lavandula officinalis and Thymus vulgaris were determined by gas chromatography and mass spectrometry. GC/MS analysis of T. vulgaris resulted in thymol as the major oil component where as methyl sulfony exhibited as the most abundant constituent of L. officinalis. The antibacter...

The antimicrobial activity of three Salvia species, i.e. S. santolinifolia, S. hydrangea and S. mirzayanii, essential oils were investigated. The essential oils were obtained from the aerial parts of plants and analyzed by GC-MS. The main constituents of aforementioned species were alpha-pinene (72.4%), beta-pinene (6.6%) and limonene (5.3%); beta-caryophyllene (25.1%), 1,8-cineol (15.2%) and c...

the usage of antimicrobial materials for coating meat products, in addition to reducing the microbial population and increase of the quality safety of products, be greatly reduced usage of nitrites as preservatives and synthetic carcinogens. compounds that have antimicrobial activity can be mixed, stabilized or incorporated with edible coatings. spices and vegetable extracts are also a group of...
