Özet
The aim of this study was to cultivate Sideritis spp. taxa that are naturally distributed in the province of Isparta, Türkiye and evaluate agricultural performance. The taxa investigated included Sideritis perfoliata L., Sideritis hispita P.H.Davis, Sideritis libanotica Labill. subsp. linearis ((Benth.) Bornm., Sideritis libanotica subsp. libanotica, Sideritis condensata Boiss. & Heldr., Sideritis cilicica Boiss. & Balansa, Sideritis congesta P.H.Davis & Hub.-Mor., Sideritis stricta Boiss. & Heldr., Sideritis leptoclada O.Schwarz & P.H.Davis, Sideritis syriaca subsp. nusairiensis (Post) Hub-Mor., Sideritis pisidica Boiss. & Heldr., Sideritis phrygia Bornm., Sideritis dichotoma Huter and Sideritis erythrantha var. erythrantha. Twelve of these taxa are endemic to the region. Successful cultivation was achieved in nine species among these taxa: S. perfoliata, S. hispita, S. libanotica subsp. linearis, S. libanotica subsp. libanotica, S. condensata, S. congesta, S. stricta, S. leptoclada, and S. syriaca subsp. nusairiensis. These species showed high total phenolic content values and high antioxidant activity in both wild and cultivated conditions. The highest total phenolic content (mg GAE/g dry sample) values were found in Sideritis libanotica subsp. Linearis, with 14.06 mg/g GAE in wild conditions and 12.56 mg/g GAE under cultivation conditions. Among all taxa, the highest antioxidant activity was for Sideritis leptoclada in wild conditions. SPME analyses showed the main volatile compounds under wild conditions were: β-pinene (18.12-5.66%), trans-caryophyllene (12.77-0.83%), and germacrene-D (10.59-0.67%) in Sideritis condensata. In Sideritis perfoliata, the primary compounds were α-pinene (51.72-43.36%), β-pinene (14.07-12.25%), and limonene (10.96-14.09%), while in Sideritis hispita, they were α-pinene (22.86-13.74%), β-pinene (28.31-16.39%), and trans-caryophyllene (11.24-14.49%). Other species such as Sideritis libanotica subsp. linearis, Sideritis libanotica subsp. libanotica, Sideritis stricta, Sideritis leptoclada, and Sideritis syriaca subsp. nusairiensis showed varying dominant compounds including α-pinene, β-pinene, germacrene-D, caryophyllene, and bicyclogermacrene. For Sideritis congesta, the highest compound concentrations were trans(β)-caryophyllene (25.03%), β-bisabolene (13.24%), and bicyclogermacrene (9.47%), while other compounds varied between wild conditions and cultivated conditions, including β-pinene, dl-limonene, α-pinene, (Z)-2-heptenal, Z-3-hexenyl 2-methylbutanoate, and benzoate
