to investigate the effects of zataria multiflora boiss essential oil (zmb) on incidence of ascites syndrome and blood parameters of arian broiler chicks, an experiment with 500 one-day-old chicks were conducted. this experiment was based on completely randomized design with 5 treatments including 1) control (basal diet), 2) basal diet with 100 mg/kg probiotic, 3) basal diet with 150 mg/kg avila...

myocardial infarction (mi) is a common presentation of the ischemic heart disease. lavandula angustifolia is a herbaceous plant with antioxidative effects.this study was designed to investigate the cardioprotective effects of lavandula angustifolia essential oil against isoproterenol-induced mi in rats.the dried sample was subjected to hydrodistillation by using a clevenger and the oils were dr...

An indicator of bypassing is a premature drop in gas-oil ratio; i.e., earlier than expected collapse of gas saturation. Early gas collapse (water fillup) may indicate that channeling has occurred. In layered reservoirs with no or little vertical crossflow, water injection in an initially depressurized layer will cause GOR to drop rapidly. Often naturally fractured reservoirs exhibit fast gas co...

Essential oils on the market were analyzed using GC-MS and the main ingredients of each essential oil were quantified. Analysis of the essential oil of Lavandula officinalis (lavender oil) showed that each sample had a different ratio of the contents of main ingredients, such as linalool, linalyl acetate, and camphor. In addition, some commercial lavender oils were analyzed by GC-MS for compari...

ecosystem pollution and weed resistance to herbicides have led researchers to pay more attention to natural herbicides. to examine allelopathic effects of liquorice, rosemary, chamomile and eucalypt on germination characteristics and early growth of wheat (triticum aestivum l.) and wild oat (avena fatua l.), a factorial experiment based on completely randomized design with 20 treatments and fou...

background: nanosilver particles are among the potentially candidates for modulating the redox status and changing the growth, performance and quality of plants because of their physicochemical characteristics.   objective: this study was carried out to elucidate the potential effects of nanosilver particles application on variations of photosynthetic pigments (chlorophyll and carotenoids) and ...

The essential oils of the fruits and the leaves of pistachio (Pistacia vera L.) were analyzed by GC and GC/MS. Fresh unripe pistachio fruits were richer in essential oil (0.5%, w/w) than the leaves (0.1%, w/w). Twenty one compounds were identified in the essential oil of the fruits and the major components were (+)-alpha-pinene (54.6%) and terpinolene (31.2%). The enantiomeric ratio of the majo...

Saffron essential oil has a pleasant aroma and medicinal activities. However, it is sensible into the environmental condition. Therefore, it should be protected against unwanted changes during storage or processing. Encapsulation is introduced as a process by which liable materials are protected from unwanted changes. In the present study, different ratios (0:100, 25:75, 50:50, 75:25, and 100:0...
