The biomass i.e. wheat-hemlock used in this study was first characterized for its composition. The physical and chemical characterization of biomass was estimated using proximate analysis, calorific value, crystallinity, devolatilization behaviour, ultimate analysis, ICP-MS of ash, FT-IR, XRD, CHNS, and HPLC analysis. For commercial purpose the same biomass was used for conversion to bio-oil by...

ABSTRACT: Olives belong to the family of olea europaea L. is a popular fruit tree. The fruit and the oil extracted from it is consumed worldwide particularly in the Mediterranean regions. In this study changes in the fatty acid composition of the oil extracted from olive fruit during the course of maturation is investigated. This work is concerned with the best harvesting point when oleic acid ...

Improvement of oxidative stability of soybean oil by blending with a more stable oil was investigated. Autoxidation of blends and interesterified blends (9:1, 8:2, 7:3 and 1:1, w/w) of soybean oil and palm olein was studied with respect to fatty acid composition, fatty acid location and triacylglycerol composition. Rates of formation of triacylglycerol hydroperoxides, peroxide value and volatil...

A novel longitudinal feeding design was used to investigate the controlling influence of dietary fatty acids on the dynamic incorporation of fatty-acyl chains into phosphatidylcholine, phosphatidylethanolamine and cardiolipin in inner membrane of cardiac mitochondria. Rats were fed a polyunsaturated-fatty-acid-rich oil (soya-bean oil) for 12 days, crossed-over to a monounsaturated-fatty-acid-ri...

The influence of fatty acid composition and tocopherol on cholesterol oxidation in fish, flax, sunflower, and palm oil to which cholesterol was added were examined during storage and heating. The contents of cholesterol oxides in all oils increased (p < 0.05) during storage and heating. Total cholesterol oxides in fish oil were higher (p < 0.05) than that in vegetable oils. Addition of R-tocoph...

  Background: Lavender’s essential oil is commonly used in aromatherapy and massage. Its major clinical benefits are on the central nervous system. Linalyl acetate and linalool are the most predominant chemical constituents in the essential oil of Lavandula angustifolia.   Objective: Comparison of super critical fluid extraction (SCFE) and hydrodistillation (HD) methods on Lavander΄s essential ...

The physicochemical properties and fatty acid composition of Attalea dubia (Mart.) Burret (indaiá) seed oil were investigated. The oil was extracted in a soxhlet apparatus using petroleum ether and evaluated for iodine, acid, peroxide, ester, and saponification values. The oil was also analyzed using infrared and nuclear magnetic resonance spectroscopy. The fatty acid profile of the oil was de...

objectives: the objective of this research was to investigate the chemical composition and antibacterial activities of the fatty acids and essential oil from various parts of ligularia persica boiss (l. persica) growing wild in north of iran. materials and methods: essential oils were extracted by using clevenger-type apparatus. antibacterial activity was tested on two gram-positive and two gra...

objective: this study is designed to extract and examine chemical composition, antimicrobial and antioxidant activity of the hydro-distillated essential oil of murraya koenigii leaves from the south region of tamilnadu, india. matherials and methods: gas chromatography (gc) and gas chromatography-mass spectrometry (gc-ms) analysis of the essential oil result was indicates the 33 different compo...

background: thymus deanensis is a known aromatic plant which grows widely in iran and many mediterranean regions. in previous studies composition of essential oils of many species of thymus genus reported which they were rich of phenols like thymol and carvacrol. methods: water distilled essential oils from aerial parts of thymus deanensis var. deanensis from three different localities in iran ...
