Background & Aim: Tanacetum is a member of Asteraceae family and its twelve species such as Tanacetum walteri are endemic to Iran. In this investigation, chemical compounds and antimicrobial activity of essential oils of Tanacetum turcomanicum (Krash.) and Tanacetum walteri (C.Winkl.) were studied. Experimental: The pla...

Ruta species are known as a potential source of natural products with biological activities. They are used in several fields such as in therapeutic and traditional medicine. In order to contribute to the valorization of these plants, this work investigated the chemical composition and antibacterial activity of the essential oils of Ruta montana and Ruta gravelons growing in tunisia (north o...

As one of the major biofuels to replace fossil fuel, biodiesel has now attracted more and more attention due to its advantages in higher energy density and overall less greenhouse gas generation. Biodiesel (fatty acid alkyl esters) is produced by chemically or enzymatically catalyzed transesterification of lipids from microbial cells, microalgae, oil crops, or animal fats. Currently, plant oils...

we studied the antioxidant activities of the essential oils of zataria multiflora boiss. (zeo) and bunium persicum (boiss.) b. fedtsch (beo) in mixed form on linseed oil using (dpph•), ­(­abts•+), h2o2 scavenging, and reducing power assays. after calculation of ic50 for zeo and beo separately, interactions of the essential oils were investigated at the form of mixture and the results were given...

Ferulago angulata subsp. carduchorum (Boiss. & Hausskn.) D.F. Chamb is a perennial species of the family Apiaceae and is locally used as a flavouring agent and for some medicinal properties. The essential oil of this plant if found to possess antibacterial and antifungal activities. The present study is aimed to determine constituents of essential oils from inflorescence of four F. angulata sub...

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...

The efficacy of target-released butyric acid, medium-chain fatty acids (C(6) to C(12) but mainly lauric acid) and essential oils (thymol, cinnamaldehyde, essential oil of eucalyptus) micro-encapsulated in a poly-sugar matrix to control necrotic enteritis was investigated. The minimal inhibitory concentrations of the different additives were determined in vitro, showing that lauric acid, thymol,...

Background Hydro-distillation (HD) method is a traditional technique which is used in most industrial companies. Microwave-assisted Hydro-distillation (MAHD) is an advanced HD technique utilizing a microwave oven in the extraction process. Methods In this research, MAHD of essential oils from the aerial parts (leaves) of rosemary (Rosmarinus officinalis L.) was studied and the results were co...
