Introduction: The members of the genus Tanacetum are important medicinal plants. This study investigated the chemical composition and antibacterial activity of Tanacetum lingulatum and Tanacetum polycephalum essential oils on human infectious bacteria. Methods: The aerial part of two plants were collected from Urmia Province, Iran. The essential oils were extracted using a Clevenger device. The...

Essential oil extracted from the leaves of Myrtle, Myrtus communis L. (Myrtaceae)was tested in vitro for volatile toxicity against two stored-product insects (Tribolium confusum and Callosobruchus maculatus). The chemical composition of the plant oil was examined by gas chromatography-mass spectrometry (GC-MS). The major oil components were α-pinene (10.4%), α- Terpineol (10.1%), linalool (9.0%...

Fresh leaves of Litsea glutinosa (Lour.) C. B. Rob. from Ha Tinh were steam distilled to produce an oil in 0.15% yield. The essential oil was analysis by a combination of capillary GC and GC/MS. Seventy eight compounds were detected in the oil, of which more than 95.18% were terpenoids. The major components were (E)-β-ocimene (13.35%), β-caryophyllene (27.20%) and bicyclogermacrene (18.16%). Ke...

the essential oils of the aerial parts of three different artemisia species (a.scoparia, a. diffusa, a. turanica ) growing wildly in the northeast of iran were analyzed by gc-ms. twenty-two, twenty-six, and thirteen components were identified in the essential oils of these plants, respectively. the major constituents of the oil ofa. scoparia were b-pinene (16.10%), carvacrol (13.81%), limonene ...

In order to study the response of concentration and composition of essential oil of coriander (Coriandrum sativum) to cattle manure and nitrogen fixing bacteria, an experiment was conducted as factorial experiment in the base of randomized complete blocks design with twelve treatments and three replications at homand research station in Damavand of Iran in 2010. The factors were cattle...

Hydro-distilled volatile oil from the aerial parts of Chenopodium ambrosioides L. (Chenopodiaceae) was obtained and the oil was analyzed by a combination of GC and GC/MS. Air-dried aerial parts of Chenopodium ambrosioides (100 g) which were collected from Anzaly in Mazandaran province at full flowering stage on June 2003, were subjected to hydro-distillation for 3.5 h using a Clevenger-type app...

this study was conducted to evaluate the effects of different proportions of lemon bee brush essential oil on growth performance, carcass composition, and hematology and biochemical parameters of common carp (cyprinus carpio). common carp with an average weight of 8 ± 0.2 g were fed for one month with a diet supplemented with lemon beebrush essential oil (0.15 and 0.3 ml) and with normal diet a...

The physicochemical properties, composition and antimicrobial activity of cinnamon essential oil (Cinnamomum zeylanicum) were studied. The bioactivity of this essential oil against Paenibacillus larvae was analyzed by means of a combination of in vitro techniques, such as the tube dilution method and bioautography, a method employed to localize antibacterial activity on a chromatogram. Cinnamal...
