The solubilities of two different non-psychoactive cannabinoids i.e., cannabigerol (CBG) and cannabidiol (CBD), in supercritical carbon dioxide (CO 2 ) have been determined at 315, 326 and 334K and in the pressure range from 11.3 to 20.6MPa. These solubility data have been compared to the previously determined solubilities of two psychoactive cannabinoids i.e., (−)-Δ 9 -tetrahydrocannabinol (Δ 9 -THC) and cannabinol (CBN), in supercritical CO 2 . An analytical method with a quasi-flow apparatus was used for the experimental determination. Within the investigated temperature and pressure range, the molar solubility of CBG ranged from 1.17 to 1.91×10 −4 and the molar solubility of CBD ranged from 0.88 to 2.69×10 −4 . The solubility of the different cannabinoids in supercritical CO 2 increases at 326K in the following order: Δ 9 -THC<CBG<CBD<CBN. The solubility data were correlated using the Peng–Robinson equation of state in combination with Van der Waals mixing rules. Deviations between calculated results and the experimental data ranged from 0.81 to 6.35% absolute average relative deviation (AARD), except for CBD at 334K, where the AARD was 18.4%.
