Özet:

In this study, it was investigated essential oil yield and compositions of endemic mountain tea (Sideritis libanotica Labill. and Sideritis bilgerana P.H. Davis) cultivated in Konya ecological conditions, Turkey. The essential oil yield of cultivated Sideritis libonitica Labill. flowers was 0.20 % while the essential oil yield of Sideritis bilgerana P.H. Davis flowers was 0.15%. The highest essential oil components were determined as 19.82 % β-pinene, 14.60 % α-pinene from Sideritis bilgerana P.H. Davis; 25.92 % hexadecanoic acid and 21.49% δ- cadinene from Sideritis libonitica Labill. According to the results of this study, it was determined that significant differences between essential oil yield and components of cultivated the endemic mountain tea species in Konya ecological conditions were determined.
