Two species belonging to the genus Salvia (Salvia brachyodon Vandas and Salvia officinalis L.) from Dalmatian region were studied for their essential oil composition, genome size and base composition. These species showed the same chromosome number (2n 1⁄4 14), similar genome size (0.95 and 0.97 pg/2C) and base composition (38.52 and 38.55 GC%), respectively. This is the first estimation of DNA...

BACKGROUND The cholesterol-lowering abilities of rice bran's fiber and oil apart from its fatty acid composition remain unclear. OBJECTIVE The objective of the study was to assess the effects of defatted rice bran and rice bran oil in an average American diet on blood lipids in moderately hypercholesterolemic persons. DESIGN Study 1 used a parallel-arm design. Twenty-six healthy volunteers ...

Tanacetum santolinoides, Essential Oil Composition, n-Hexane-Ether Extract Composition The essential oil of the aerial parts of Tanacetum santolinoides was analyzed by capillary GLC and GLC-MS. Altogether 30 components were identified. The main constituents were thymol (18%), trans-thujone (17.5%), trans-chrysanthenyl acetate (13.2%), cis-chrysanthenyl acetate (9.2%), umbellulone (9.7%) and 1,8...

in this study, the oil yield, fatty acid (fa) composition and the physicochemical and quality characteristics of salvia macrosiphon crude seed oil were determined. the main fatty acids ranked in the following order of abundance: α- linolenic acid> linoleic acid> oleic acid. the n3 /n6 fa ratio and polyunsaturated fa/ saturated fa ratio were 1.6 and 7.23, respectively. the fa composition reveale...

The essential oil from the aerial parts of Salvia sclarea L., growing wild in Tajikistan, were obtained by hydrodistillation and analyzed by gas chromatography – mass spectrometry. A total of 59 compounds were identified representing 94.2% of total oil composition. Major components of the essential oil were linalyl acetate (39.2%), linalool (12.5%), germacrene D (11.4%), α-terpineol (5.5%), ger...

Peppermint (Mentha × piperita L.) was transformed with various gene constructs to evaluate the utility of metabolic engineering for improving essential oil yield and composition. Oil yield increases were achieved by overexpressing genes involved in the supply of precursors through the 2C-methyl-D-erythritol 4-phosphate (MEP) pathway. Two-gene combinations to enhance both oil yield and compositi...

Purpose: Suitable ratio of essential fatty acids has an important role in maintaining good health. There is no pure oil with an ideal fatty acid composition and oxidative stability. The main goal of the present study was to evaluate the physical, chemical and nutritional properties of oil obtained by blending flaxseed oil as a rich source of ω3 fatty acids with sesame and olive oils. Methods: T...

The chemical composition of the volatile oil from aerial parts of Hypericum triquetrifolium Turra was studied by GC-MS. Fifty components (97.1% of the total composition) were detected in the volatile oil. Germacrene-D (21.7%), β-caryophyllene (18.3%), δ-cadinene (6.4%), trans-β-farnesene (4.3%), α-humulene (3.8%), β-selinene (3.7%), γ-cadinene (3.3%) and trans-phytol (3.2%) were found to be the...

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...

the genus hypericum is one of the most important medicinal plants that contain 17 species in iran, three of them are endemics. this paper reports the essential oil composition of eight hypericum species from iran. the essential oil analysis of a number of the studied plants has already been reported but their report from iran may be valuable for scientists.  samples collected from different pla...
