|Isolation and characterization of known or unknown bioactive compounds from complex mixtures have always been important challenge for researchers. Preparative fractionation of compounds is one of the most widely discussed applications in essential oil studies. In scope of ongoing research projects, mono-, sesqui- and diterpenes were precisely separated by using preparative gas chromatography (Prep-GC) technique from different essential oils with a high purity (>95%). In this context, the compounds such as limonen-10-al (monoterpene) from the aerial part oil of Dracocephalum moldavicum, suberosin (sesquiterpene) and 3,7(11)-eudesmadien-2-one (sesquiterpene ketone) from the fruit oil of Prangos pabularia and the leaf oil of P. heyniae respectively, 11-hydroxy-2,4-cycloeudesmane (juglaterpene) from the leaf oil of Juglans regia, 4-acetoxymethy-2-[(5-methyl-1-methylene)-hex- 4-enyl]-1-methyl-1-4-methy-pent-3-enyl)-cyclobutane (diterpene) from the fruit oil of Ammi visnaga and cis- and trans-artemidin (isocoumarin) from the aerial part of oil of Crinitaria tatarica have been successfully isolated and identified by using different spectroscopic techniques (NMR, MS, IR etc.). In similar way, enantiomeric separations were also performed for (+)-carvone from Anethum graveolens, (+)-piperitone from Mentha pulegium, (+)-pulegone from Ziziphora bungeana, (+)-linalool from Nepeta italica, (-)-linalool from Ocimum basilicum, (-)-menthol from Mentha piperita and (-)-β-pinene from Achillea grandifolia essential oils by using different chiral GC columns.|
