SUMMARY Chemical Composition and Antimicrobial Activities of the Essential Oils of
Some Teucrium L. Taxa In this study, the composition of the essential oils obtained from the air-dried Teucrium chamaedrys L.subsp. chamaedrys, Teucrium orientale L. var. puberulens (T.Ekim), and Teucrium chamaedrys L. subsp. lydium (O.Schwarz) were analyzed by GCMS. Thirty-six, thirty-five, and thirty-three components identified in the essential oils. Germacrene D (16.7%) was the most abundant constituent in T. chamaedrys subsp. chamaedrys, -caryophyllene was the most abundant component in both T. orientale var. puberulens, and T. chamaedrys subsp. lydium in ratios 21.7 and 19.7%, respectively. The isolated essential oils of the plants were tested for antimicrobial activity and showed moderate antibacterial activity against Gram-positive and Gram-negative bacteria, but no antifungal activity was observed against two yeastlike fungi. Key Words: Teucrium chamaedrys subsp. chamaedrys, T. orientale var. puberulens, T.
chamaedrys subsp. lydium, Lamiaceae, Essential oil, Antimicrobial activity, GC-MS.
