The volatile constituents of the aerial parts of Varthemia. persica DC. var. persica, growing wild in Iran, were investigated by GC-MS. Sixty seven constituents were identified. ?-Cadinene (9.7%), Selin-11-en-4-?-ol (5.30%), Germacrene D (4.9%), Bicyclogermacrene (4.7%), ??Muurolene (4.7%), ?-Eudesmol (4.52%), ?-Himachalen oxide (3.6%), ?-Eudesmol (3.54%), ?-Bourbonene (3.21%) were found to be...

the volatile constituents of the aerial parts of vervain (verbena officinalis l.) cultivated locally were investigated. analysis of the volatile fraction by gc and gc-ms is described. compounds were identified by various methods, the major compounds being 3-hexen-1-ol (7.28%), 1-octen-3-ol (32.76%), linalool (4.66%), verbenone (20.49%) and geranial (7.22%).

background & aim:  non-steroidal anti-inflammatory drugs (nsaids) are commonly used in clinical medicine. the adverse effects they produce in the gastrointestinal tract however, often limit their utility. oxidative stress has been shown to occur in the small intestine in response to the oral administration of indomethacin. in view of this, the effect of thyme essential oil, an agent with an...

BACKGROUND: Chicken meat is susceptible to microbial and chemical contamination and using antimicrobial agents helps to prolong its shelf-life. OBJECTIVES: This study focuses on the effect of chitosan-based coating and Trachyspermum ammi essential oil on qualitative properties of refrigerated chicken fillet meat. MATERIAL and METHODS: chicken fillets treated with chitosan solution (2 %wv-1) and...

Molecular distillates of butter oil consisting of the four most volatile 2.5% cuts (obtained by a redistillation of the first 10% cut), the next most volatile 40% cut, and the 50% residue obtained from 777 pounds of oil were subjected to fractionation by adsorption and gas-liquid chromatography. Only the most volatile 2.5oj, cut, which contained 10% unsaponifiable matter, was examined in detail...

A steam distilled volatile oil obtained from the leaves of Chrysanthemum indicum Linn. (FamilyCompositae) was analyzed by capillary GC and GC-MS. The volatile oil mainly comprises of thirty nine (39) components out of which thirty one (31) constituents comprising 82.6% of the oil were identified. The volatile oil mainly contains monoterpenes (48.1%). Isoborneol, a monoterpene, was the predomina...

Cyperus rotundus L. has been widely distributed in China. In the exploration of Cyperi Rhizoma to pat attention on its geoherbalism is very necessary. The current index of quality control for Cyperi Rhizoma and Cyperus rotundus-volatile oil is the αCyperone contained in the Cyperus rotundus-volatile oil, different processing methods influence the content of their αCyperone. On the basis of the ...

Background and objectives: Scrophularia umbrosa Dumort is used as a traditional herb in China. In this study, chemical profile, free radical suppression capability, general toxicity and cardiovascular activities of the volatile compounds from S. umbrosa were investigated. Moreover, methanol (MeOH) extract of rhizomes were analyzed to purify and identify the co...
