J.R.Edm., S. albida L. subsp. condensata (Rech.f.) J.R.Edm., and S. albida L. subsp. velenovskyi (Rech.f.) Greuter et Burdet from Turkey were analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GUMS), simultaneously. Linalool (20% and 29%) was identified as major component in the oils of'S. albida subsp. albida and S. albida subsp. condensata oil, respectively. In the oil of S. albida subsp. colchica, hexadecanoic acid (13%) was found as major component. beta-Caryophyllene (20%) was the main component of the oil of S. albida subsp. velenovskyi.
