The study was aimed at investigating the antimelanogenic and antioxidant properties of essential oil when extracted from the leaves of Artemisia argyi, then analyzing the chemical composition of the essential oil. The inhibitory effect of the essential oil on melanogenesis was evaluated by a mushroom tyrosinase activity assay and B16F10 melanoma cell model. The antioxidant capacity of the essen...

 The study aims to determine the influence of frying (shallow and deep) with olive, canola and sunflower oil on fatty acid composition of silver carp < /font>. Frying by olive oil and canola oil increased the monounsaturated fatty acids (MUFA) significantly (p < 0.05) that consequently decreased saturated fatty acids (SFA), polyunsaturated fatty acids (PUFA) and ω-3 fatty acids. Frying by sunfl...

Dietary fat plays a major role in obesity, lipid metabolism, and cardiovascular diseases. To determine whether the intake of different types of dietary fats affect the muscle fiber types that govern the metabolic and contractile properties of the skeletal muscle, we fed male Wistar rats with a 15% fat diet derived from different fat sources. Diets composed of soybean oil (n-6 polyunsaturated fa...

background & aim:mentha longifolia (l.) huds is an aromatic perennial herb that belongs to the   family lamiaceae. the aim of this study was to identify chemical composition of aerial parts   (including leaf, stem and flowers) of m. longifolia collected from   (kamu mountain) isfahan province. experimental: the essential oils were extracted   using the hydrodistillation method and analysed by g...

chamomile is a medicinal plant with high economic value. in this research, 20 chamomile ecotypes collected from different regions of iran were evaluated for genetic and chemical diversity. dna was extracted by ctab and polymerase chain reaction was performed using 13 rapd markers. essential oils extraction was performed by water distillation using clevenger system. components of the essential o...

Many industrial fermentations use complex medium containing both carbohydrate and oils as their carbon sources. Oil supplements have been shown to increase the antibiotic titre and are a cheaper alternative carbon source, in terms of carbon per unit volume, when compared to carbohydrates. Oil supplements are also preferred on an energy supply basis and have natural antifoam properties. The majo...

Quantitative information regarding the endmember composition of the gas and oil that flowed from the Macondo well during the Deepwater Horizon oil spill is essential for determining the oil flow rate, total oil volume released, and trajectories and fates of hydrocarbon components in the marine environment. Using isobaric gas-tight samplers, we collected discrete samples directly above the Macon...

Hydrodistillation of berries and leaves of Juniperus phoenicea grown in Sinai yielded volatile oils in the yield of 0.36 and 1.96%, respectively. Using gas chromatography/mass spectrometry technique, fifty eight compounds were identified in berry oil representing 99.2% of the oil composition. alpha-Pinene was the major compound in berry oil (39.30%) followed by sabinene (24.29%). Berry oil comp...

In general olive oil is defined on the basis of its sensory characteristics. European Union (EU) regulations establish the organoleptic quality of virgin olive oil by means of a panel test, evaluating positive and negative descriptors (EU regulations). For the organoleptic assessment, several volatile compounds are considered as the main responsible for negative and positive attributes. Volatil...

The fatty acid and volatile compound compositions of camellia oil were analyzed in this study. The impacts of the replacement of conventional vegetable oil with camellia oil on the sensory attributes of dried seaweed were also determined. C18:1 (83.59%), followed by C16:0 and C18:2, were the most abundant fatty acids in camellia oil. A total of 11 and 32 volatile compounds were identified in ca...
