Essential oil composition of two endemic Nepeta L. (Lamiaceae) taxa from Southwestern Turkey

Abstract

Nepeta L. is one of the important genus in the Lamiaceae family. It includes ca. 300 herbaceous species and mostly grows in Eurasia. Nepeta is represented in Turkey by 40 taxa and of these 16 are endemic. Nepeta species are commonly utilized in traditional medicine by the local people, primarily as spasmolytic, diuretic, and bronchodilator agents. As a consequence of studies on Nepeta taxa, terpenoids and flavonoids have been identified as the most common components. In this report, chemical contents of two endemic Nepeta taxa (N. viscida from Buharkent/Aydin and N. nuda L. subsp. lydiae from Altinyayla/Burdur) were presented. The main constituents were determined as ?-terpineol (20.59%), trans-?-caryophyllene (9.90%) and spathulenol (9.37%) for N. viscida, and 1,8-cineole (31.31%), borneol (18.95%) and caryophyllene oxide (14.59%) for N. nuda subsp. lydiae. © IJSM 2022.
