Abstract :In this study, it was aimed to compare the volatile components of Sideritis condensata Boiss. Et. Heldr. Apud Bentham species mountain tea collected from nature and grown under field conditions with HS-SPME GC-MS technique. The cuttings of the plant were collected from Isparta Province, Yenişarbademli District, rocky location of Dedegöl Mountain in April 2020, and were transferred to field conditions at the end of May in the same year after rooted in a greenhouse environment. In June-July 2021, during the flowering period, leaf and flower samples peculiar to the species were collected from both field and natural environments and dried under room conditions. Using solid based micro-extraction technique, 72 volatile components were determined in natural growing environment and 88 volatile components in field envi-ronment in S. condensata by gas chromatography mass spectrometry (GC-MS). Among the volatile com-ponents found in natural habitat and field environment, α-pinene (9.30%-2.32%), β-pinene (18.12%-5.66%), β-ocimene (4.46%-1.06%), trans-caryophyllene (12.77%-0.83%), germacrene-D (10.59%-0.67%), γ-cadinene (2.09%-10.94%), α-gurjunene (0.03%-16.68%), farnesene (0.98%-6.00%) were identified as the main components of Sideritis condensata. When the volatile components were examined, it was obser-ved that sesquiterpene hydrocarbons were high.
