Solubilities prediction of ginger bioactive compounds in liquid phase of water by the COSMO-RS method
The solubilities in water of four main ginger bioactive compounds, 6-gingerol, 6-shogaol, 8-gingerol and 10-gingerol, were predicted using a conductorlike screening model for real solvent (COSMO-RS) calculations. This study was conducted since no experimental data are available for ginger bioactive...

The solubilities in water of four main ginger bioactive compounds, 6-gingerol, 6-shogaol, 8-gingerol and 10-gingerol, were predicted using a conductorlike screening model for real solvent (COSMO-RS) calculations. This study was conducted since no experimental data are available for ginger bioactive compounds solubilities in liquid phase of water. The s-profiles of these selected molecules were calculated using Gaussian software and the solubilities were calculated using the COSMO-RS method. The solubilities of these ginger bioactive compounds were calculated at 50–200 °C. In order to validate the accuracy of the COSMO-RS method, the solubilities of five hydrocarbon molecules were calculated using the COSMO-RS method and compared with the experimental data in the literature. The selected hydrocarbon molecules were 3-pentanone, 1-hexanol, benzene, 3-methylphenol and 2-hydroxy-5-methylbenzaldehyde.
