Composition of the essential oils of two Sideritis species from Turkey and antimicrobial activity
The genus Sideritis (Lamiaceae) is represented in Turkey by 46 species and altogether 55 taxa, 42 taxa being endemic [1, 2, 3]. Some species of Sideritis are used as medicinal and aromatic plants. S. perfoliata L. is known as “adacayi, dagcayi, and Kandil cayi” in different regions of Turkey and are widely used as diuretic and in the treatment of coughs and gastrointestinal disorders . S. trojana Bornm. is an endemic species for Turkey and is known as “kazdagi cayi” [4, 5].
The essential oil compositions of some Sideritis species have been subjected to previous studies. Previous phytochemical investigations of S. perfolita and S. trojana have revealed the presence of diterpenes [6, 7], fatty acids , and essential oils [9, 10].
The composition of the essential oil of S. perfoliata was investigated and limonene was identified as the major constituent . In our previous work, 8α-13-hydroxy-14-en-epilabdane (26–29%), limonene (19–24%), viridiflorol (14%), sabinene (11%), and...
