The β2-adrenergic effects of macerated extract, aqueous extract, ethanol extract, and essential oil of Carum copticum, 5 nM propranolol, and saline were tested by performing cumulative Log concentration-response curves of isoprenaline-induced relaxation of precontracted isolated guinea pig tracheal chains in three different conditions including: non-incubated (group 1, n=9) incubated with 1...

This study was outlined to examine the chemical composition of hydrodistilled essential oil and in vitro antioxidant potentials of the essential oil and different solvent extracts of endemic Phlomis bourgaei Boiss. used as folk remedy in Turkey. The chemical composition of the oil was analyzed by GC and GC-MS, and the predominant components in the oil were found to be β -caryophyllene (37.37%),...

abstract: the growing interest in substitution of chemical food preservatives by naturalones has fostered researchs on plantessentiak oils and extracts. in this study effect of different concentrations of zataria multiflora boiss. essential oil (0, 0.005, 0.015 and 0.03%) on bacillus cereus atcc 11778, (103cfu /ml), was evaluated using sterilized samples (16 bottles containing 80 ml barley soup...

Many species of the genus Eucalyptus from the Myrtaceae family are used in Brazilian folk medicine for the treatment of various medical conditions such as cold, flue, fever, and bronchial infections. In the current investigation, we evaluated the analgesic and anti-inflammatory effects of essential oil extracts from three species of Eucalyptus employing various standard experimental test models...

This study was designed to examine the chemical composition of essential oil and the in vitro antimicrobial activities of essential oil and methanol extract of Teucrium montanum. The inhibitory effects of essential oil and methanol extracts of T. montanum were tested against 13 bacterial and three fungal species by using disc-diffusion method. GC/MS analyses revealed that essential oil contains...

In a previous study, the relaxant and anticholinergic (functional antagonism) effects of Bunium persicum (B. persicum ) have been demonstrated on guinea pig tracheal chains. To elucidate the other mechanisms responsible for this relaxant effect, the inhibitory effect of this plant on histamine H1 receptors was examined in this study. The antihistaminic effects of aqueous and macerated extracts,...
