Essential oils and fatty acids composition of Tunisian, German and Egyptian caraway (Carum carvi L.) seed ecotypes: A comparative study

Alternative solvents for extraction of food aromas. Experimental and COSMO-RS study

“…The comparison detailed composition for each extract are reported in Table 3. A total of 26 major compounds (in agreement with literature: Chemat, Aït-Amar, Ahc ene Lagha & Esveld, 2005;Laribi et al, 2009;Laribi, Kouki, Bettaieb, Mougou, & Marzouk, 2013) were identified in caraway extract. The chemical class characterization of caraway seed essential oil showed the prevalence of ketones, represented by carvone (73.20%, of the total GC area), trans-dihydrocarvone (0.37%) and cis-dihydrocarvone (0.36%).…”

"Comparative study on essential oils of selected apiaceous seeds cultivated in Transylvania "

“…Caraway essential oil obtained yield was higher than some literature results (0.48-1.41) [25], but also comparable with other results obtained from literature 6 . The literature reported yields for anise seed essential oils vary from 1.4% to 6% [6,24,26,27].…”

An original approach for lipophilic natural products extraction: Use of liquefied n-butane as alternative solvent to n-hexane

“…Extraction yield using n-butane is dependent on temperature: an increase of 6.5%e10.9% could be noted by increasing extraction temperature from 20 C to 40 C. The highest extraction yield was reached for n-hexane (15% at 68 C). Caraway seeds contain up to 6 g/100 g of essential oil and a higher amount of fatty acids (up to 8 g/100 g) (Bailer, Aichinger, Hackl, de Hueber, & Dachler, 2001;Laribi, Kouki, Bettaieb, Mougou, & Marzouk, 2013). Given the extraction yields obtained, the extract is most probably a mixture of essential oil and fatty acids.…”
