EXTRACTION ET ETUDE DES HUILES ESSENTIELLES DE LA SALVIA OFFICINALIS.L CUEILLIE DANS DEUX REGIONS DIFFERENTES DE LA TUNISIE
Extraction and a study of essential oils of Salvia officinalis from two different regions in Tunisia. The composition of the essential oils of the aerial parts of Salvia officinalis, obtained by hydrodistillation, collected from two areas in Tunisia, was analyzed by GC-MS and GC-FID. The essential oils of the organic phase and those extracted from the aqueous phase, obtained from the two plants materials collected, have a different chemical composition. More than 90% of the total of components was detected. The main components are: α-thujone (26,49%- 10,58%), β-thujone (13,09%-3,09%), 1,8-cineol (31,89%-8,58%), camphor (40,14%-2,10%), the viridiflorol (18,96%-1,73%) and the caryophyllene (9,04%-0,5%). The chemotype of the Salvia officinalis studied is the α-thujone.
