Sarıkaya, Ayşe GülFakir, H.2021-03-202021-03-2020191589-16231785-0037http://doi.org/10.15666/aeer/1702_19231928https://hdl.handle.net/20.500.12885/726In this study, conducted between 2015 and 2017, 49 different volatile components were identified from Phlomis rigida Labill that was reaped from Golcuk highland located on Konya Seydisehir-Bozkir road and Phlomis monocephala P.H.Davis that was reaped from Mersin Silifke Bahcederesi Village in Turkey at three different periods (pre-flowering, flowering and post-flowering) through gas chromatography mass spectroscopy (GC-MS) after solid phase micro extraction (SPME). The main components of Phlomis rigida were found to be (E)-2-Hexenal (9.21%), beta-Calyophyllene (60.23%) and Germacrene D (9.76%). The main components of Phlomis monocephala were found to be alpha-Pinene (15.59%), (E)-beta-Farnesene (17.69%) and Germacrene D (18.92%). It was concluded that reaping P. rigida and P. monocephala species during the flowering period was important for the yield of volatile components.eninfo:eu-repo/semantics/openAccessPhlomisGC-MSGermacrene Dalpha-PineneTurkeyArticle10.15666/aeer/1702_1923192817219231928WOS:000462830400029Q4Q3
