Static headspace analysis of Gabon Estuary okoume (Aucoumea klaineana Pierre) oleoresins indicated that nine products represented the major part (>96%) of the volatile compounds: six monoterpenes (α-pinene, β-pinene, limonene, α-phellandrene, β-phellandrene, 3-carene), one monoterpenic alcohol (α-terpineol) and two other derivatives (p-cymene, eucalyptol). The relative amount of each product ap...

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...

Volatile components in cape gooseberry fruit at ripe stage were collected using headspace-solid phase microextraction, and analyzed by gas chromatography-mass spectrometry. Three solid phase microextraction fiber coatings (DVB/CAR/PDMS, CAR/PDMS, and PDMS/DVB) were tested for evaluation of volatile compounds. DVB/CAR/PDMS fiber showed a strong extraction capacity for volatile compounds and prod...

The chemical composition of laurel leaves and fruits essential oils (content of 0.917 and 0.747%, respectively) and laurel leaves extracts obtained at different pressures/temperatures by supercritical fluid extraction (SFE) were studied by GC-MS. The predominant compound in the essential oils and in CO2 extracts obtained at pressures/temperatures of 100 bar/40°C and 250 bar/40°C was 1,8-cineole...

the chemical composition of the hydrolate of citrus aurantium l. (rutaceae) flowers (neroli) grown in iran, and two commercial hydrolates were analyzed by gc/ms. thirty compounds (90.3%) were identified in the hydrolate by the use of laboratory apparatus, thirty-eight compounds (83.4%) in the hydrolate from the traditional method and fifteen compounds (98.3%) in the industrially produced sample...

In order to qualitative and quantitative study on essential oil, obtained from leaf and peel of Citrus aurantium L. cultivated in North of Iran (Sari city) the leaves and fruits were gathered on April and November 2002, respectivelly. Clevenger apparatus was used for hydro-distillation extraction in order to provide the oil of leaf and peel of Citrus aurantium L. The outputs of each essential o...

In the current study, an effective and simple procedure of extraction for four benzophenone compounds from water samples was achieved by dispersive liquid–liquid microextraction (DLLME) based on solidification floating organic droplets (SFO) with a natural monoterpene enol as extractant. As natural, high point, inexpensive, environmentally friendly hydrophobic solvent, α−terpineol selected firs...

Tagetes minuta L. belongs to Asteracea family it is an annual species native of South American, although it has become widespread throughout the world. This species is especially well adapted to disturbed habitats. Tagetes minuta oil found a good market in perfumery and flavour industry. Many studies on Tagetes minuta have reported that the composition of exteracted volatile components varied a...
