  • Figure 1. From the left: tobacco leaves, basic solution for extraction, concentrate solution containing nicotine
  • Figure 2. TLC treatment with ninhydrin should result in a dramatic purple color if the nicotine is present
  • Figure 3. From the left: CoCl2 (pink); CoCl2 and nicotine (green complex); cigarette for extraction; Cu(NO3)2 and nicotine (green complex); Cu(NO3)2 solution (light blue)
  • Figure 4. Hot solution presented in Figure 3, observe the differences in the Co solutions
  • Figure 5. a) ESI spectrum of nicotine from tobacco extraction; b) ESI-ms/ms spectra of peak at 163.04 and fragmentation patterns of nicotine
  • Figure 6. ESI spectrum of Co-nicotine solution from the green solution obtained in the qualitative experiment
  • Figure 7. ESI-MS/MS spectra of Co-NIC complexes. On the left: ESI-MS/MS spectra of the peak at m/z= 580 and fragmentation patterns (loss of a nicotine ligand); on the right: ESI-MS/MS spectra of the peak at m/z= 561 and fragmentation patterns (loss of a nicotine ligand)
  • Figure 8. ESI spectrum of Cu-nicotine solutionfrom the green solution obtained in the qualitative experiment
  • Figure 9. ESI-MS/MS spectra of the peak at m/z= 448.69 and fragmentation patterns (loss of a nitrate)
