Response surface methodology for optimization of supercritical fluid extraction of orange peel essential oil
Background: Orange peel essential oils were obtained using supercritical fluid extraction. This method is an important high scaling extraction methods that used for extraction of plant and animal extracts. Methodology: The experimental parameters of SFE such as temperature, pressure, and extraction time and modifier volume were optimized using a central composite design after a 24-1fractional ...

chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
15 صفحه اولHigh Boiling Compounds of Neutral Essential Oil from Tea 1029 TABLE I. FRACTIONATION BY SILICA-GEL COLUMN CHROMATOGRAPHY
gaschromatography (PGLC) as shown in Fig. 2. Fraction C had a typical aroma of tea, and the yield was about 10 g. In this com munication, we wish to report components in the fraction. Fraction C was subjected to silica gel column chromatography using solvents system as shown in Table I and the eluate was collected every 100 ml, which was analyzed by GLC. The eluate was finally separated into te...
متن کاملEXTRACTION OF CITRONELLA (Cymbopogon nardus) ESSENTIAL OIL USING SUPERCRITICAL CO2: EXPERIMENTAL DATA AND MATHEMATICAL MODELING
Citronella essential oil has more than eighty components, of which the most important ones are citronellal, geranial and limonene. They are present at high concentrations in the oil and are responsible for the repellent properties of the oil. The oil was extracted using supercritical carbon dioxide due to the high selectivity of the solvent. The operational conditions studied varied from 313.15...
متن کاملDetermination of bactericidal efficacy of essential oil extracted from orange peel on the food contact surfaces
Essential oil was extracted from peels of sweet orange fruits by supercritical technique and the resulting compounds were analyzed by gas chromatography. After emulsifying with tween-20 in sterile water, the antibacterial efficacy against Vibrio parahaemolyticus, Salmonella typhimurium, Escherichia coli, and Staphylococcus aureus, which were inoculated on the surfaces of samples of stainless st...
