Supercritical CO2 extraction of Tetraclinis articulata: Chemical composition, antioxidant activity and mathematical modeling

- SC-CO2 extraction of Tetraclinis articulata was performed at 90, 280 and 1000 bar.
- Extraction yields varied from 0.61 (HD) to 25.5 g/kg (SC-CO2 1000 bar).
- SC-CO2 volatile oil exhibited higher antioxidant activity than HD essential oil.
- The extraction process at 90 bar was shown to be limited by solid-fluid equilibrium.
