the leaves of arum conophalloides (araceae) were used in some west areas of iran as a dessert. the aerial parts of the herb were collected from sahneh mountains, kermanshah province, west of iran and was hydrodistilled by klevenger-type apparatus. composition of the essential oil was determined by gc and gc/ms. totally, 18 components (92% of total essential oil) were identified. the oil contain...
ABSTRACT Background and Objectives: Due to their antimicrobial, anticancer and antioxidant properties (due to the presence of free radical scavengers), essential oils and extracts of medicinal plants are of great importance as natural medicinal compounds in public health, treatment of diseases, and protection of raw and processed foods.&...
This experiment was conducted to investigate the effects of flaxseed essential oil (0, 60 or 120 mg/kg) on chemical composition, aerobic stability, and in vitro gas production of alfalfa silage. Experimental treatments include: alfalfa treatment without additive (control), alfalfa with 60 mg/kg flaxseed oil and alfalfa with 120 mg/kg flaxseed essential oil, which were kept at room tempe...
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Background & Aim: Purslane (Portulaca oleracea L.), belongs to the Portulacaceace family, grows in many parts of Iran. Results of previous studies were indicated purslane is a rich source of essential fatty acids of omega-3 and omega-6. Portulaca oleracea is a widespread weed, being the eighth common plants of the world. The Aim of current study was to compare the essential f...
ABSTRACT Background and objectives: Utilization of essential oils instead of chemical preservatives has received significant attention in recent years. The present study aims to evaluate chemical composition and antibacterial and antioxidant properties of essential oils of Zataria multiflora, Artemisia deracunculus and Mentha piperita. Methods: Chemical profile of th...
The potential of three arbuscular mycorrhizal fungi (AMF) - Glomus mosseae, G. fasciculatum and G. intraradices- to enhance the production of essential oil and plant growth parameter was investigated in sweet basil (Ocimum basilicum). The AMF inoculation significantly increased plant height, fresh and dry matter yield, oil content and oil yield as compared to non-inoculated basil plants. Essent...
Growth regulators play a crucial role during plant growth and development and utilizing of them can a possible approach to improving plants economic yield. In this research, the effects of two elicitors [salicylic acid (SA) and indole acetic acid (IAA)] on the accumulation of essential oils in the shoot cultures of Mentha piperita L. and Melissa officinalis L. were studied.
