Thirty-one and fourty constituents were identified in the oils of both plants, representing 96.33 and 98.23% of the total oil. While alpha-pinene (9.65%), camphene (9.46%), eucalyptol (9.18%), thujone-cis (24.59%) and camphre (23.06%) were established as major constituents of S. officinalis L., alpha-pinene (3.62%), camphene (5.26%), camphre (26.76%), borneol (8.91%) and eucalyptol (40.11%) were found as major constituents of S. fruticosa
