- •
Extraction of three antioxidants by ionic liquids (ILs) was studied.
- •
ILs containing hydroxyl group had better extraction ability for gallic acid.
- •
The role of hydrophobic interaction between ILs and solutes should be considered.
- •
Hydrogen bonding was the main driving force for the extraction of the three acids.
