Essential components of the aerial parts of Œnante virgata have been studied by gas chromatography-mass spectrometry to afford 27 component, the major components were found to be, Citral (41.71%), α-Bisabolol (21.81%) Dihydrocarviol acetate (11.37%). The antimicrobial activitiy of the essential oils were evaluated by disc diffusion method and tested against Gram-negative Escherichia coli, Staph...

aluminum is very sensitive to oxidation reactions. if a fresh surface of melt is exposed to air, it oxidizes quickly and an oxide layer covers the melt surface. new oxide films formed in a very short time during casting are thin and folded. the metal surface can be folded and create a double-oxide film as a result of the melt turbulence. the entrance of this double-oxide film into the melt is o...

BACKGROUND The current chemotherapy for cutaneous leishmaniosis (CL) has a series of drug limitations such as toxic side effects, long duration, high costs and drug resistance, which requires the development of new drugs or effective alternatives to the CL treatment. Essential oils (EOs) are complex mixtures of secondary metabolites from various plants. It has been shown that several EOs, or th...

chemical constituents of the essential oil of flowers of lavandula officinalis chaix. growing in isfahan, iran, were studied by tlc and gas chromatography-mass specrtometery (gc-ms) methods. twelve components which constitute 94.8% of the examined oil were identified. the main constituents were linalool (34.1%), 1,8-cineole (18.5%), borneol (14.5%), camphor (10.2%), terpinen-4-ol (4.5%), linaly...
