Abstract:
The genus Origanum is represented in Turkey by 22 species or 32 taxa, 21 being endemic to
Turkey. The rate of endemism among the Turkish Origanum species is 63%. Out of 52 known
taxa of Origanum, 60% are recorded to grow in Turkey. Origanum saccatum is called as "Tahtac?
Keki?i" in Alanyaregion around Antalya. It grows on the slopes at limestone rocks and the pine
forests. It is endemic for C3 and C4 squares.
In this study, essential oil content and compositions of four O. saccatum plants were collected
from Ermenek (Southern part of Turkey). The altitudes of collected places of plants were 1196
m, 1323 m, 1449 m and 1523 m from sea level. The essential oil content of O. saccatum plants
was hydro-distilled by Clevenger apparatus, and they were determined between 0.20% and
0.33%. The highest essential oil content (0.33%) was obtained from 1196 m. The composition
of essential oils was analyzed by GC/MS. The main components were: p cymene (37.91 to
49.21%), carvacrol (6.71 to 27.58%), ?-terpinene (6.04 to16.69%), Isoborneol (6.31 to 12.56%). |
