The essential oil of Rosmarinus officinalis L. (rosemary) was obtained by hydro-distillation and analysed by gas chromatography-mass spectrometry. Sixty-two constituents were identified, representing 98.06% of the total oil content. Oxygenated monoterpenes were the predominant components. The rosemary oil was characterized as having prominent (> 5%) contents of camphor (18.9%), verbenone (11.3%...

Rosemary (Rosmarinus officinalis L.) has traditional reputations that justify investigation for a potential role in reducing widespread cognitive decline in the elderly. A randomized, placebo-controlled, double-blinded, repeated-measures crossover study was conducted to investigate possible acute effects of dried rosemary leaf powder on cognitive performance. Twenty-eight older adults (mean age...

The compostion of the oils from flower and leaf of Achillea mellifolium L. subsp. mellifolium were collected during the flowering priod from Lar area to Damavand montain, altitude 3400 m in July 2003. The essential oils obtained by different methods of distillation (steam distillation and hydro-distillation), the percentage of oils for flower and leaf by steam distillation were 0.2 and 0.05% an...

background: rosemary (rosmarinus officinalis l.) as a member of the lamiaceae family is a valuable aromatic and medicinal plant which is cultivated in large scale in iran. therefore, it is necessary to determine influence of factors affecting plant growth and drug metabolite production. objectives: this experiment was carried out to evaluate the effects of bio-stimulators compounds on growth an...

This study investigated the cytotoxic activity of Rosmarinus officinalis L. (rosemary) aqueous extract on the cell cycle of Allium cepa. To this end, crude aqueous leaf extracts at four concentrations, 0.02, 0.04, 0.06 and 0.08 mg/mL, were tested on A. cepa meristematic root cells, at exposure times of 24 and 48 h. Slides were prepared by the crushing technique, and cells analyzed throughout th...

The leaf essential oil yields of clementine, cypress, rosemary, tea, and thyme were 0.22, 0.87, 1.46, 1.20, 0.72%, respectively, based on the dry weight plant material. oils contained highest levels oxygenated monoterpenes (60.14-91.70%). Rosemary tea rich in 1,8-cineole (49.98% 57.55%, respectively), they have potent antifungal activity against Alternaria alternata strain (MIC = 5000 μg/ml). T...
