| Steam distillation or chromatography of wood and wood residues can release terpenes. |
| He experimented by exposing paraffin wax to crushed Salvia leaves and found the solid wax readily adsorbed the volatile terpenes from the air. |
| Essential oils contain many terpenes, which are rapidly absorbed through the lungs and cross the blood-brain barrier. |
| Petrichor comes from atmospheric haze, which contains the terpenes, creosotes and other volatile compounds that emanate from plants. |
| Larger terpenes are uncommon, with the exception of polymeric isoprene, well known as rubber. |
| We conclude that the role of terpenes in Eucalyptus-marsupial folivore interactions is secondary. |
