“…The Tunisian oil 18 had a high content of sesquiterpene hydrocarbons (5.1%). The results presented herein were in line with those of the previous works, 19,20 but revealed some differences due to geographical origin. According to a previous study, 21 α-pinene and 1,8-cineole constituted the major fraction of Tunisian M. communis oil; α-pinene is found in level above 50%.…”

The essential oils from Thymus capitatus (L.) Hoffmgg. et Link, Ocimum basilicum (L.), Myrtus communis (M.) and Laurus nobilis (L.) have been characterized and tested against two bacteria (Lactobacillus plantarum and Escherichia coli) and a fungus (Geotrichum candidum), using a submerged broth culture method. The results obtained showed that T. capitatus and O. basilicum were the greatest inhibitors of all the strains tested, and that Escherichia coli was more inhibited than Lactobacillus plantarum by all the essential oils tested.

“…The chemical composition of L. nobilis volatile oil from different locations has been studied by different researchers. In all studies, 1,8-cineole was the major component with percentages ranging between 26.70% and 68.48% [14,30]. Moreover, alpha-terpinyl acetate with percentages ranging between 0.65-25.70% [31,32] and terpinen-4-ol with percentages ranging between 1.50-4.56% [32,33] were found as major components.…”

In this study, the components of the volatile oil obtained from Laurus nobilis leaves by steam distillation were determined using Agilent 6890 Gas Chromatography (GC) -5975 Mass Spectrometry (MS). The antioxidant activities of different extracts of L. nobilis leaves were determined by using DPPH • (2,2-diphenyl-1picrylhydrazyl) free radical scavenging activity, β-carotene-linoleic acid bleaching assay and ABTS •+ (2,2'-azinobis(3-ethylbenzothiazoline-6-sulphonic acid) cation radical decolorization assay. Determination of the total phenolic contents of L. nobilis leaf extracts were performed using the Folin-Ciocalteau procedure and total flavonoid contents were measured using a spectrophotometric assay. According to the GC/MS results, 1,8-cineole (46.16%), alpha-terpinyl acetate (10.62%), alpha-pinene (6.27%), terpinen-4-ol (5.07%) and sabinene (4.99%) were found to be the major compounds in volatile oil. The obtained volatile oil was used to make skin care lotion. Stability tests and organoleptic analyses of final product were performed after 1, 5, 30 and 90 days of production. The highest amounts of total flavonoid content were found to be 5.48 ± 0.65 and 8.60 ± 0.12 µg QEs/mg in ethyl acetate and ethanol extracts, respectively. The highest amounts of total phenolic compounds were found to be 54.42 ± 0.14 and 25.32 ± 0.10 µg PEs/mg in ethyl acetate and ethanol extracts, respectively. According to the results of ABTS •+ , DPPH • and β-carotene linoleic acid assays, ethyl acetate extract was found to be the most active extract (24.98±0.87 µg mL -1 , 75.65±0.77 µg mL -1 and 19.32±1.04 µg mL -1 ).

Headspace solid-phase microextraction analysis of volatile components of spices

SummaryHeadspace solid-phase microextraction (HSSPME) coupled with gas chromatography-mass spectrometry (GC-MS) has been used to isolate volatile compounds from three different spices (basil, oregano, and bay leaves). SPME conditions were optimized before the experimental extractions, to achieve optimum recovery of the volatile compounds. Method reproducibility and linearity were evaluated. Relative standard deviations (RSD) bel',,veen 1.4 and 9.3% were obtained. Typical components of the essential oils of spices and other plant materials, e.g. terpenes, hydrocarbons, and oxygenated terpenes were identified. These results indicate that headspace SPME coupled with GC-MS is an excellent method for analysis of the odors of spices.
