Essential Oil Variability in Indigenous Ppopulations of Dalmation Sage (Salvia officinalis L.)

Essential oils of 25 indigenous populations of Dalmatian sage (Salvia officinalis L.) from Croatia and Bosnia and Herzegovina were analyzed using analytical gas chromatography (GC/FID) and gas chromatothography - mass spectrometry (GC/MS) techniques to check for biochemical variability. The percentage of essential oil ranged from 1.93% to 3.70% with average of 2.83%. Out of 62 compounds detected eight were found in concentrations higher than 5% in at least one sample and were considered as major: cis-thujone, camphor, trans-thujone, 1, 8-cineole, β-pinene, camphene, borneol and bornyl acetate. Using multivariate analyses on the basis of eight major compounds, three chemotypes were distinguished: (A) cis-thujone, (B) trans-thujone and (C) camphor/β-pinene/borneol/bornyl acetate. The chemotypes differed significantly in six out of eight main essential-oil compounds as well as in total thujone content and cis-/trans-thujone ratio.
