Extraction of Essential Oils of L. by Two Different Methods: Hydrodistillation and Microwave Assisted Hydrodistillation.

The extraction of essential oils is generally carried out by two main techniques: azeotropic distillation (hydrodistillation, hydrodiffusion, and steam distillation) and extraction with solvents. However, these traditional methods are a bit expensive, especially since they are extremely energy and solvent consuming. This work consists in studying two methods of extraction of the essential oils of L.
