Aqueous solubility is often a limiting factor in any concentration-dependent process and n-octanol/water partition coefficient, usually expressed as log P, is equilibrium between surrogate of nonaqueous biophases and water phase. The aqueous solubility of seven liquid monoterpenes: (+/-)-beta-citronellol, (+/-)-linalool, linalyl acetate, (-)-alpha-pinene, (-)-beta-pinene, eucalyptol and terpine...
This study examined the effects of odors on sustained attention during a vigilance task. Two essential oils (lavender and eucalyptus) and two materials (l-menthol and linalyl acetate) were compared with a control. The increase in reaction time was significantly lower with lavender than with the control. The results suggest that the administration of lavender helped to maintain sustained attenti...
The essential oil content in the inflorescence of lavender (Lavandula angustifolia Mill.) cultivated in the mid hills of Uttarakhand was found to be 2.8 % based o n the fresh weight. The oil was an alysed by capillary GC and GC– MS. Thirty seven constituents, representing 97.81 % of the o il were identified. The major components of the oil were linalyl acetate (47.56 %), linalool (28.06 %), lav...
مریم گلی کارواندری یا مورپوژو (Salvia mirzayanii Rech. f. & Esfand) یکی از انواع گونههای انحصاری جنس Salviaاست که متعلقبه خانواده لابیاته میباشد. سرشاخه گلدار تازه این گونه معطر دراواخر اسفندماه از خاش جمعآوری و به روش تقطیر با آب استخراج وسپس ترکیبهای موجود در آن با استفاده از گاز کروماتوگراف متصل شده باطیف سنجی جرمی (GC/MS) شناسایی گردیدند. اسانس حاصله از این گیاه با بازده 0.9% حاوی 28 ت...
Peel and leaf oils of 58 mandarin cultivars, belonging to 15 different species were obtained from fruits and leaves collected on mandarin-trees submitted to the same pedoclimatic and cultural conditions. Their chemical composition was investigated by capillary GC, GC/MS and 13C NMR and the results were submitted to a cluster analysis and a discriminant analysis. Three major chemotypes, limonene...
