The polymers from mastic gum of Pistacia lentiscose and subspecies of Pistacia atlantica, (sp. kurdica, mutica and cabolica) have been isolated and characterised by gel permeation chromatography (GPC) and 13C NMR spectroscopy as cis-1,4-poly-?-myrcenes. They were screened against Helicobacter pylori and other Gram-negative and Gram-positive bacteria to evaluate their antimicrobial action. In or...
Photoluminescence of plant extract solutions has been investigated for discrimination of plant life forms (grasses, forbs, and shrubs) using principal component analysis (PCA). Clippings from each of six plant species representing three different plant life forms potentially found in the diets of free-ranging herbivores in the Chihuahuan Desert of North America were investigated for possible di...
The chemical entities of Mastic, Kurdica, Mutica and Cabolica gums from genus Pistacia have been isolated and characterised by GC-Mass Spectrometry, High Performance Liquid Chromatography and Column Chromatography. These chemical entities were screened for anti-microbial activities against nine strains of Helicobacter pylori and some other Gram-negative and Gram-positive bacteria. The most bioa...
Background and purpose: Nowadays consumers are cautious about foods and are more interested in foods that are less processed. This has led to significant approaches and replacing chemical preservatives in food products by different natural components. The essential oil of Satureja edmondi is used as a flavoring agent and known as a pharmaceutical plant because of its antimicrobial characteristi...
Oxidation of low-density lipoprotein (LDL) has been strongly suggested as a key factor in the pathogenesis of atherosclerosis. Thus the inclusion of some anti-oxidant compounds such as Satureja Khozistanica,vitamin E and coenzyme Q10 in daily dietary food stuff may inhibit the production of oxidized LDL and may decrease both the development and the progression of atherosclerosis. The present st...
Background and Objective: Utilization of plants as antioxidants in food processing is a hope for substitution of synthetic antioxidants. Biological properties of Saturejasahendica Bornm. essential oils have not been studied yet. Materials and Methods: Ferrous ion chelating, nitric oxide radical scavenging and cytotoxicity of S. sahendica and commercial Satureja essential oils were studied. Re...
In this study, we aimed to determine chemical composition and antibacterial activities of Satureja hortensis and Calamintha nepeta against to 20 phytopathogenic bacteria causing serious crop loss. The essential oils of S. hortensis and C. nepeta were isolated by the hydrodistillation method and the chemical composition of the essential oils were analyzed by GC-MS. The antibacterial properties o...
