'Mato Peiyu' pomelo (Citrus grandis (L.) Osbeck 'Mato Peiyu') leaves from pruning are currently an agricultural waste. The aim of this study was to isolate essential oils from these leaves through steam distillation (SD) and solvent-free microwave extraction (SFME) and to evaluate their applicability to skin care by analyzing their antimicrobial, antioxidant (diphenyl-1-picrylhydrazyl scavengin...

background & aim: ziziphora l. genus belongs to the lamiaceae family, which has important medicinal and aromatic plant species. in current study, essential oil chemical compositions of two ziziphora l. species (z. tenuior l. and z. clinopodioides lam.) were investigated. experimental: the flowering branches of z. tenuior and z. clinopodioides were collected in spring and summer 2011. the ae...

tomato fusarium wilt, caused by fusarium oxysporum f. sp. lycopersici (fol), is one of the most important diseases of tomato in iran and in the whole world. recently, in order to reduce hazardous effects of chemical pesticides, these days, attempts have been made to use safer methods for controlling plant pathogens. therefore, using antifungal plant materials has been highly regarded during pas...

the effect of thyme and ajowan essential oils (200µg/l and 300µg/l respectivilly ) on growth of aflatoxin-producing strain of aspergillus parasiticus on 2 stages of pistachio (green and with dry peel ) was studied . also organoleptic tests for evaluating odor and flavor residual of essential oils on pistachio were also performed tested . the collected data were statistically analyzed. the resul...

background: malaria and leishmaniasis are two most significant parasitic diseases which are endemic in iran. over the past decades, interest in botanical repellents has increased as a result of safety to human. the comparative effi- cacy of essential oils of two native plants, myrtle ( myrtus communis ) and marigold ( calendula officinalis ) collected from natural habitats at southern iran was ...

objective: oxidation of oils has an important effect on nutritional and organoleptic properties of foodstuffs. nowadays, new tendency has created a necessity to use natural compounds such as essential oils for producing functional foods. in this study, antioxidant, antifungal, and organoleptic properties of zataria multiflora boiss.(zmeo) and cinnamon zeylanicum essential oils (czeo) have been ...

abstract       background and objective: the aim of this study was to determine the chemical composition, antibacterial and antifungal effects of thymus vulgaris and cuminum cyminum essential oils against foodborne pathogens and candida species in vitro.       methods: the essential oils were extracted from the aerial parts of thymus vulgaris and dried cuminum cyminum seeds using a clevenger ap...

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...

fumigant toxicity of essential oils from foeniculum vulgare (apiaceae), teucrium polium (lamiaceae) and satureja hortensis (lamiaceae) were evaluated against the adults of cowpea seed beetle, callosobruchus maculatus exposed for 24h. essential oils were obtained through steam-distillation using a clevenger-type apparatus. bioassays were conducted at 28±2 °c and 60±5% r.h. in dark conditions. si...
