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...

This study was designed to examine the chemical composition of essential oil and the in vitro antimicrobial activities of essential oil and methanol extract of Teucrium montanum. The inhibitory effects of essential oil and methanol extracts of T. montanum were tested against 13 bacterial and three fungal species by using disc-diffusion method. GC/MS analyses revealed that essential oil contains...

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...

Artemisia afra is a medicinal plant with antimicrobial activities, known to treat tuberculosis, measles, cough, and influenza. In consequence, its applications have increasingly become pivotal control various microbes which cause different diseases. This study therefore, evaluated the chemical composition antifungal activity of A. essential oil. The extraction oil was done using steam distillat...
