Methods
| Ion source | ChemZo (BioChromato) |
| Mass Spectrometer | compact QTOF (Bruker) |
| Measurement Method | 1g each of commercially available aromatic herbs (coriander, rosemary, sage, and thyme) was rubbed with a mortar and pestle to introduce the aromatic components into the MS through a tube. |
| Data Processing | Extraction of aromatic components from mass spectra using Spectra Scope and Data Analysis software. |
Results
Fig. 1 shows the TICs of the four aromatic herbs. Rosemary, sage, and thyme of the Perilla family showed similar intensities, while coriander of the Apiaceae family showed low intensities. Fig. 2 shows the mass spectra (30-second sample). Ions of 1,8-cineole and 2-dodecenal were detected in the three species from the Perilla family, and in coriander.
