Thymus daenensis is a medicinal plant endemic to semi-arid regions of Iran. A field experiment using a randomized complete block design with four replications was conducted to evaluate the effect of 20, 50 and 80% soil water depletion on morpho-physiological traits, essential oil content and composition and water use efficiency of T. daenensis during 2010-2011. Water stress reduced growth, ...

chemical compositions  and antimicrobial effects on E.coli and S.aureus of essential oils from lavandula anguifolia and salvia officinalis were stuied.disk diffusion method was conducted to evaluate the zone of microbial growth inhibition at 1,1:.2,1:.8 and 1:16 dilutions of the essenial oils at four stages of zero(fresh oil).1,2 and 3 months post-exeaction.the antimicrobial effect was also stu...

satureja sahendica bornm. is an endemic medicinal plant which grows wild in natural habitats of west and north-west regions of iran. in this study, for domestication of satureja sahendica and study it's essential oil content and composition, the seeds of seven populations were collected from natural habitats and cultivated in three replications as a complete randomized blocks design. the a...

the essential oil from the seeds of cuminum cyminum l. was isolated by hydrodistillation method and the chemical composition was determined by gas chromatography-mass spectrometry (gc/ms). the yield of the oil was found to be 3.0% (on dry weight basis). a total of twenty six components, representing 96.7% of the oil were identified. cuminaldehyde (49.4%), p-cymene (17.4%), b-pinene (6.3%), a-ter...

Tribolium confusum and Sitophilus oryzae are stored product pests found worldwide. Environmental damages, human health issues the emergence of resistance driving scientists to seek alternatives synthetic insecticides for its control. Under this scenario, plant secondary metabolites being increasingly studied as bioinsecticides because they renewable, natural, biodegradable, non-persistent in en...

Aims: This study aimed to the extraction of Melaleuca cajuputi essential oils by microwave-assisted method. The comparison for productivity method and traditional hydro-distillation was also established figure out optimum condition isolation process.
 Methodology: Microwave-assisted employed oils. components contained in were analyzed gas chromatography-mass spectrometry. Standard methods ...

Objectives: Zataria multiflora Boiss has been used as a conventional medicinal plant for treating infections in traditional medicine. Therefore, the aim of this work was to reveal composition and antibacterial effect leaves essential oil. Materials Methods: Z. oil isolated through two different methods: hydro isolation steam isolation. Essential analyzed by gas chromatography–mass spectrometry ...

Bay laurel leaves, also known as bay are an important herb in many cuisines around the world. In addition to their use cooking, leaves have been used for medicinal properties and thought anti-inflammatory antimicrobial effects. Gas chromatography/mass spectrometry (GC-MS) device was determine secondary metabolites essential oil of samples kept at different temperatures (−22, −20, −18, 2, 4, 6, ...
