BACKGROUND: Autoxidation is an irreversible reaction which occurs with the effect of oxygen in the air, and results in unpleasant taste and smell that are known as the signs of rancidity in oil. OBJECTIVES: In this study, the antioxidant potential of clove, summer savory and tarragon essential oils (EOs) in grape seed oil was evaluated. METHODS: Effects of EOs at different concentrations (0.3, ...

fumigant toxicity of various doses of essential oils (185.2, 370.4, 555.5, 740.7, 925.4, 1111.1, and 1296.3 µl/l water) from five officinal plants, including rosemary (rosmarinus officinalis), lavender (lavandula vera), fennel (foeniculum vulgare), tarragon (artemisia dracunculus)and summer savory (satureja hortensis)on two stored products pests, cowpea weevil (callosobruchus maculatus) and red...

two-spotted spider mite (tetranychus urticae koch), is one of the most seriously important  polyphagous pests that causes considerable damage to agricultural crops. in recent years, due to problems associated with the use of synthetic pesticides, herbal essential oils have received due attention as natural plant pest control compounds. in the present study, repellency effect of herbal plant ess...

introduction savory (satureja hortensis l.) is an annual herbaceous plant that belongs to the lamiaceae family. nowadays, the use of biofertilizers is increased in agriculture and their role in increasing the crops production has been demonstrated in many research works (vessey, 2003; chen, 2006; mahfouz & sharaf- eldin, 2007). one of the most important visions is sustainable production of enou...

plant growth promoting bacteria with various mechanisms such as an increase in uptake and availability of nutrients can improve plant growth. in order to evaluate the effects of biofertilizers and vermicompost on quantitative characteristics and essential oil content of vegetative parts of summer savory, a field experiment was conducted during growing season of 2008- 2009 at agriculture researc...

In this study, the variability of essential oil composition in different parts of summer savory was investigated. Extraction of essential oils from air-dried leaves and healthy seeds was done using water-distillation in Clevenger-type apparatus for 4 h. In total, 23 and 24 components were identified in the leaves and seeds of summer savory, respectively. Carvacrol (46.023%), Estragole (Methyl C...

to evaluate the effect of different levels of nitrogen fertilizer and municipal compost on the essential yeild of savory pot experiment in 2009 was carried out in the darab region. different doses of compost was in four levels, including: zero c0:, 10c1:, 20c2: and 30c3: tons per hectare and nitrogen fertilizer include: zero n0:, 30n1:, 60 n2: and 90n3: kg of pure nitrogen from urea per hectare...

background: summer savory (satureja hortensis l.) is one of the most important medicinal and spice plants cultivated in many parts of the world. objective: a greenhouse experiment was conducted to study the effects of feso4 and citric acid application on the morphological traits and essential oil content and its component, gamma-terpinene in s. hortensis. methods: feso4 in four levels (0, 3, 4 ...
