Figure 10: Thymol signals from the one-dimensional 13C NMR spectrum of T. transcaucasicus flowers. Flowers were harvested and extracted with chloroform 12 days after the labelling with 13CO2 (4 hours). The solvent was CDCl3. The spectrum was processed with MestReNova Software (zero filling 256k). The original spectrum was multiplied by a Gaussian window function of 0.7 Hz except for signals C-8/9 and C-5. For signal C-8/9 and signal C-5 a function of 0.5 Hz and of 1.2 was applied. The numbering of the carbon atoms is displayed in Figure 3.
