Essential Oil Composition of Stachys antalyensis Y. Ayasligil and P.H. Davis Described Endemic Species from Turkey

Abstract

The essential oil obtained from the aerial parts of Turkish endemic
 
Stachys antalyensis Y.Ayasligil and P.H. Davis (Lamiaceae) has been
 
studied. Plant material of S. antalyensis was collected from the locality:
 
C3 Çandir (Isparta), Yazili Canyon Nature Park in Turkey. Aerial parts
 
of plants were dried in shadow than the leaves and flowers were separated
 
from the stems. The essential oil was extracted from the leaves and
 
flowers by hydro distillation method. The average content of essential
 
oil was obtained as 0.2 %. The water-distilled essential oil from dried
 
leaves and flowers of this species was analyzed by GC-MS. A total of
 
19 components, representing 94.5 % of the oil, were characterized. The
 
major component of essential oil was bicyclogermacrene as 29.4 %.
 
The other important compounds were identified such as β-caryophyllene,
 
spathulenol, β-pinene, viridiferol and elemol.
