This experiment was conducted to investigate the effects of flaxseed essential oil (0, 60 or 120 mg/kg) on chemical composition, aerobic stability, and in vitro gas production of alfalfa silage. Experimental treatments include: alfalfa treatment without additive (control), alfalfa with 60 mg/kg flaxseed oil and alfalfa with 120 mg/kg flaxseed essential oil, which were kept at room tempe...
Purpose: To investigate the chemical composition and insecticidal activity of the essential oil of the aerial parts of Paederia scandens against the maize weevil, Sitophilus zeamais. Methods: Steam distillation of the aerial parts of P. scandens was carried out using Clavenger apparatus in order to obtain the volatile oils. Gas chromatography/mass spectrometric (GC/MS) analyses (HP-5MS column) ...
Background & Aim: By increasing resistance of fish pathogens to chemical drugs, using herbal plants with antimicrobial properties is necessary.In this study, the composition of the essential oil and antimicrobial activity of aerial parts of Achillea wilhelmsii C.Koch growing wild in Zagross mountain (Southwest of Iran) was analyzed against common bacterial and fungal pathogens of fish....

The roots and rhizomes of Tanacetum parthenium (L.) Schulz. Bip. (Asteraceae), have been used in Iranian traditional medicine under the name of Aqhovan, as digestive and stomachic tonic. Composition of the essential oil, which was obtained from the root of T. parthenium collected from Karaj, was determined by gas chromatography, combined GC/MS and GC/IR. In total, 20 components (92% of essentia...

The chemical composition of the essential oil obtained from aerial parts of Galium verum L. (Rubiaceae) from Iran was examined by a combination of GC and GC/MS. The oil isolated by hydro-distillation using a Clevenger-type apparatus. Air-dried aerial parts of Galium verum (80 g) which were collected from Bomehen in Tehran province at full flowering stage on May 2003, were subjected to hydro-dis...
