Sažetak
To identify how many chemotypes of Salvia officinalis exist in Montenegro, the chemical composition of the essential oils of 12 wild–growing populations was determined by GC–FID and GC/MS analyses. Among the 40 identified constituents, the most abundant were cis–thujone (16.98–40.35%), camphor (12.75–35.37%), 1, 8–cineol (6.40–12.06%), trans–thujone (1.5–10.35%), camphene (2.26–9.97%), borneol (0.97–8.81%), viridiflorol (3.46–7.8%), limonene (1.8–6.47%), alpha–pinene (1.59–5.46%), and alpha–humulene (1.77–5.02%). The composition of the essential oils under study did not meet the ISO 9909 requirements, while the oils of populations P02–P04, P09, and P10 complied with the German Drug Codex. A few of the main essential–oil constituents appeared to be highly intercorrelated. Strong positive correlations were observed between alpha–pinene and camphene, camphene and camphor, as well as between cis–thujone and trans–thujone. Strong negative correlations were evidenced between cis–thujone and alpha–pinene, cis–thujone and champhene, cis–thujone and camphor, as well as between trans–thujone and camphene. Multivariate analyses allowed the grouping of the populations into three distinct chemotypes, i.e., Chemotype A, rich in total thujones, Chemotype B, with intermediate contents of thujones, alpha–pinene, camphene, and camphor and high borneol contents, and Chemotype C, rich in camphor, camphene, and alpha–pinene. The chemotypes did not significantly differ in the total essential–oil content and the cis/trans–thujone ratio.
