Abstract
A comparative study between hydrodistillations with and without ultrasons, was carried out for the extraction of essential oils of Melaleuca armillaris leafs cultivated in Tunisia.
We studied, for each method, the yield and the chemical composition of essential oils obtained.
The chromatographic analysis of essential oils by GC-MS, shows that the majority compounds are the same for both oils: 1.8-cinéole, borneol, α-pinene, γ-terpinene.
The extraction under ultrasons allows a better output to be obtained in a shorter time.
The extraction of essential oils of Melaleuca armillaris under ultrasons is moreover more effective than that by simple hydrodistillation.
