Figure 3.6 Two-dimensional gas chromatogram of an orange oil extract, in which a 2 s
heart-cut has been made in the region A where -mrycene has eluted on a non-polar column.
Secondary analysis on a polar Carbowax 20M column indicated two compounds (marked B
and C), both identified as ‘odorous’ by organoleptic assessment. Reproduced from P. A.
Rodriguez and C. L. Eddy, J. Chromatogr Sci. 1986, 24, 18 (32).
