Synopsis

The objective of this work is a comparative study, on the one hand, between two methods of extraction of essential oils of Inula viscosa, namely a conventional process which is the training with water vapor (EV) and an innovative process that is the training of steam assisted by microwave (EVMO), and on the other hand, a qualitative and quantitative comparative study between essential oils of inula viscosa harvested in two different regions: Algiers and Boumerdes. The GC-MS analysis of two samples demonstrated the impact of the Microwave Assisted Steam Drive (EVMO) extraction method on the chemical composition and is considered the best process to preserve volatile compounds. The various tests and analyses have proven that the essential oils of the Boumerdes region give better results than those of the Algiers region in terms of yield and composition, this difference is probably due to the climate difference between the two regions.
