Özet

Teucrium chamaedrys L. is a member of the Lamiaceae family and is represented in the Flora of Turkey by six subspecies. The aerial organs of 7: chamaedrys L. subsp. trapezunticum RECH. fit. and subsp. syspirense (C. KOCH) RECH. fil. bears numerous eglandular and glandular trichomes. Eglandular trichomes are simple, long-multicellular with cuticular micropapillae and glandular hairs are of peltate and capitate types. The peltate hairs consist of a basal cell, a short unicellular stalk, and multicellular secretory head, and the capitate ones possess 1-2 stalk cells and one glandular head cell. The aerial parts were subjected to microdistillation for the isolation of volatiles. The analysis was simultaneously performed by using gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). The major components were characterized as beta-caryophyllene (18%), nonacosane (12%), germacrene D (11%), caryophyllene oxide (7%), and a-pinene (7%) for subsp. trapezunticum, and caryophyllene oxide (23%), alpha-pinene (11%), and caryophyllenol II (5%) for subsp. syspirense.
