Essential Oils Chemical Variability of Seven Populations of Salvia Officinalis L. In North of Albania

Abstract

Essential oils from seven populations of Dalmatian sage from the North of Albania were extracted and analyzed according European Pharmacopeia 7.0. The yield differed from 1.95 to 2.75% v/w. The GC-FID-MS analysis of the sage oil revealed 42 constituents. Camphor (20.50-29.74%), followed by α-thujone (19.87-24.29%), 1,8-cineole (6.88-12.64%) and β-thujone (4.00-9.14%) were predominant constituents in all analyzed populations, representing 55.70-68.00% of the total components. All of the analyzed sage populations from northern Albania comply with ISO 6571/2008 standard and European Pharmacopeia 7.0. for Dalmatian sage essential oil content, while only four populations met the requirements of the ISO 9909/1997 standard for Dalmatian sage essential oil’s composition.
