[Ionic liquid based ultrasonication-assisted extraction of essential oil from the leaves of and conductor-like screening model for realistic solvents study].

Ionic liquids (ILs) based ultrasonic-assisted extract has been applied for the extraction of essential oil from leaves. The effects of temperature, sonication time, and particle size of the plant material on the yield of essential oil were investigated. Among the different ILs employed, 1-ethyl-3-methylimidazolium acetate was the most effective, providing a 9.
