MULTIDIMENSIONAL CAPILLARY GC-CC FOR THE ANALYSIS OF REAL COMPLEX SAMPLES - PART II - ENANTIOMERIC DISTRIBUTION OF MONOTERPENE HYDROCARBONSAND MONOTERPENE ALCOHOLS OF COLD-PRESSED AND DISTILLED LIME OILS

The enantiomeric distribution of sabinene, beta-pinene, limonene, lina lool, terpinen-4-ol, and alpha-terpineol for cold-pressed Key lime oil s type A and type B, cold-pressed Persian lime oils, and distilled lim e oils has been determined by a fully automated, multidimensional, dou ble-oven (GC-GC) system using a SE-52 precolumn and a beta-cyclodextri n main column. This system allows fractions to be multransferred durin g the same GC analysis and the use of the two GCs independently when t he multitransfer option is not used. The results allow us to distingui sh cold-pressed Key lime oils type A and type B, cold-pressed Persian lime oils, and distilled lime oils. (C) 1998 John Wiley & Sons, Inc.
