Thyme (Thymus sp.), a medicinal plant of the family Lamiaceae, is used in traditional medicine, contains wide array medicinally active components, their great majority rather complex mixture thymol, ρ-Cymene, γ-Terpinene, β-Caryophyllen, etc. This study aimed to evaluate efficacy Thymus vulgaris extract against Fusarium oxysporum f. sp.radicis-lycopersici strain under saline conditions, assuming...

        The composition of the essential oils of two African (“white” and “yellow”) olibanums available in the commercial market of Isfahan (Iran) was analyzed by gas chromatography (GC) and GC-mass spectroscopy methods. The main constituents of the “White” olibanum oil were alpha-pinene (34.8%), li...

The prevalence of gastric ulcers has increased in recent years, mainly because non-steroidal anti-inflammatory drug utilization. Therefore, the current study investigates gastroprotective effect p-Cymene on absolute ethanol-induced acute mucosal hemorrhagic lesions rats. Thirty Sprague Dawley rats were randomly separated into five groups: normal control, ulcer reference, and two experimental gr...

A steam distillation extraction kinetics experiment was conducted to estimate essential oil yield, composition, antimalarial, and antioxidant capacity of cumin (Cuminum cyminum L.) seed (fruits). Furthermore, regression models were developed to predict essential oil yield and composition for a given duration of the steam distillation time (DT). Ten DT durations were tested in this study: 5, 7.5...

A diesel fuel spill was simulated on a 12-m(2) plot of agricultural land, at a concentration of 1 Lm(-2) of soil. The natural attenuation of Volatile Aromatic Hydrocarbons (VAHs) was monitored at different soil depths over a period of 50 days. The natural attenuation of VAHs in the surface layer would be attributed to two processes, namely: volatilisation (mainly linked to the boiling point of ...

Noyori et al. in 1996 showed that the Ru(II)Cl(h-pcymene)[N-p-tosyl-1,2-diphenylethylenediamine] (= [RuCl(h-p-cymene)TsDPEN]) in a HCOOH / triethylamine (TEA) mixture was able to efficiently hydrogenate substituted isoquinolines with high enantioselectivity (asymmetric transfer hydrogenation (ATH)) [1]. Almost simultaneously, the same system was reported to reduce ketones superbly by Fujii et a...

Hydro-distilled volatile oil from the aerial parts of Chenopodium ambrosioides L. (Chenopodiaceae) was obtained and the oil was analyzed by a combination of GC and GC/MS. Air-dried aerial parts of Chenopodium ambrosioides (100 g) which were collected from Anzaly in Mazandaran province at full flowering stage on June 2003, were subjected to hydro-distillation for 3.5 h using a Clevenger-type app...
