This work aimed to determine the efficacy of the essential oil of A. gratissima as anesthetic for silver catfish, and to perform the bio-guided fractionation of essential oil aiming to isolate compounds responsible for the noted effects. Fish were submitted to anesthesia bath with essential oil, its fractions and isolated compounds to determine time of anesthetic induction and recovery. Eugenol...

The inhibitory effect of Lippia alba and Lippia citriodora essential oils on dengue virus serotypes replication in vitro was investigated. The cytotoxicity (CC50) was evaluated by the MTT assay and the mode of viral inhibitory effect was investigated with a plaque reduction assay. The virus was treated with the essential oil for 2 h at 37 masculineC before cell adsorption and experiments were c...

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...

Background: Listeria monocytogenes is an important Gram-positive disease-causing bacterium existing in milk and dairy products. Inhibitory effects of Mentha pulegium essential oil at concentrations of 0.03, 0.015, and 0.0075% on growth of L. monocytogenes were studied in Iranian white cheese during 60 days of storage. Methods: Essential oil of M. pulegium plant, collected from north of Iran,...

Sweet flag, Acorus calamus L., is a member of the family of Araceae; various part of specie has Essential oil i.e. Rhizomes, root, leaves and roots. Essential oil from rhizome of Acorus calamus L. (sweet flag) growing wild in different parts of regions essential oil root of the species extracted and analyzed by GCGC-MS The yield of calamus oil was in the range of 2.94.7% by hydro stem distillat...

inhibitory effects of lavandula angustifolia and zataria multiflora essential oils were evaluated on reproduction and f1 progeny production of callosobruchus maculatus. insect’s culture and bioassays were conducted at 29 ±1ºc, 60±5% rh and dark condition. essential oils were taken by hydrodistilation. the results indicated that there was a negative and significant linear relationship between re...

Amomum maximum Roxb. is a perennial herb distributed in South China and Southeast Asia. The objective of this work was to analyze the chemical constituents and assess insecticidal and repellent activities of the essential oil from Amomum maximum fruits against Tribolium castaneum (Herbst) and Liposcelis bostrychophila (Badonnel). The essential oil was obtained by hydrodistillation and analyzed ...

To develop natural product resources to control cigarette beetles (Lasioderma serricorne), the essential oil from Artemisia lavandulaefolia (Compositae) was investigated. Oil was extracted by hydrodistillation of the above-ground portion of A. lavandulaefolia and analyzed using gas chromatography-mass spectrometer (GC-MS). Extracted essential oil and three compounds isolated from the oil were t...

In this study, Rosmarinus officinalis L. essential oil and three of its main components 1,8-cineole (27.23%), α-pinene (19.43%) and β-pinene (6.71%) were evaluated for their in vitro antibacterial activities and toxicology properties. R. officinalis L. essential oil possessed similar antibacterial activities to α-pinene, and a little bit better than β-pinene, while 1,8-cineole possessed the low...

in last two decades, considerable attempts have been made to introduce new botanical based insecticides. in this study, repellent effects of the essential oils taken from lavandula angustifolia and zataria multiflora on callosobruchus maculatus adults were evaluated. the essential oils were extracted using a clevenger apparatus. bioassays were conducted under 30±1ºc, 60±5% rh and dark condition...
