Background & Aim:According to globally development of stomach cancer especially in Ardabil, Iran, as the second major cause of mortality throughout the world, increased drug-resistant bacteria including Helicobacter pylori as the most important risk factors for stomach cancer, and side effects of antibiotics and chemical drugs normally used to treat. Expe...

background:pneumonia and respiratory tract infections, is associated with high mortality and complications in humans. current antibiotics are used to treat this infectious disease, but may lead to many problems such as unwanted side effects and resistance to antibiotics. this study investigated the antibacterial activity of the hydro alcoholic extracts of the native medicinal plants peganum har...

ÐThe essential oils from Piper capense, P. nigrum, P. guineense and P. umbellatum from S. Tome e Prõ ncipe were investigated for the ®rst time. They were analysed by GC, GC-mass spectrometry and C NMR. Monoterpene hydrocarbons were the main group of constituents in three of the samples (P. capense, P. nigrum and P. umbellatum), whereas for the other species (P. guineense) phenylpropanoid deri...

This study reports chemical composition of the essential oils and in vitro antioxidant, antimicrobial and cytotoxic activity of the volatile fraction, extracted using simulations steam distillation-solvent extraction (SDE) method, and methanolic extract from the stems and young leaves of Pterocarya fraxinifolia from Gilan, west-north of Iran for the first time. The extraction yield of volatile ...

The chemical composition of the essential oil from Hesperozygis marifolia was analyzed by gas chromatography-mass spectrometry (GC-MS), and fourteen compounds were identified. (R)-pulegone (40.75%), isomenthone (30.34%) and menthone (4.46%) were found to be the main components of the oil. The essential oil at a concentration of 2.0 mg/mL and (R)-pulegone at concentration of 0.8 mg/mL completely...

The composition of essential oil of the leaves of Lavandula stoechas ssp. stoechas, was analyzed by means of capillary GC-MS. The main components of L. stoechas ssp. stoechas oil were pulegone (40.4%), menthol (18.1%), menthone (12.6%). The essential oil of the plant was evaluated for antibacterial and a panel cytotoxic activities.
