Fig. 9. Experiment 2, comparison of N1, N7, and N11 GC traces (standardized TIC responses). Different colored sample at right (N1 – blue, N7 – green, and N11 – red) correspond to colored peaks at left (as indicated by arrows). N1 samples had higher percentages of β-pinene, N7 samples had higher percentages of α-pinene and limonene (and β-phellandrene), and N11 had higher percentages of camphene, β-myrcene and 1,8-cineole.
