In this study, conducted between 2015 and 2017, 49 different volatile components were identified from Phlomis rigida Labill that was reaped from Gölcük highland located on Konya Seydişehir-Bozkır road and Phlomis monocephala P.H.Davis that was reaped from Mersin Silifke Bahçederesi 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%), β-Caryophyllene (60.23%) and Germacrene D (9.76%). The main components of Phlomis monocephala were found to be α-Pinene (15.59%), (E)-β-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.

Medicinal and aromatic plants have a special importance with volatile oil components. Lamiaceae family members are important in pharmacology and perfumery industry because they contain volatile and aromatic oil. Origanum onites L. and Thymbra spicata var. spicata L. are the most widely used and most exported species. The volatile components of the leaves and flowers of Origanum onites L. and Thymbra spicata var. spicata taxa were determined by Headspace Solid Phase Microextraction (HS-SPME) technique combined with gas chromatography/mass spectrometry (GC / MS). 33 different components of Origanum onites were identified and the main components were p-cymene (11.45%), γ-terpinene (11.89%), linalool (14.35%), thymol (20.03%) and carvacrol (26.91%), respectively. For Thymbra spicata var. spicata L., 36 different compounds were identified and the main components were p-cymene (11.72%), γ-terpinene (10.96%), linalool (13.44%), thymol (18.92%) and carvacrol (27.34%), respectively. Oxygen containing monoterpenes have been found to be high.
