Variability of essential oil composition of Echinophora tenuifolia subsp sibthorpiana tutin by harvest location and year and oil storage

Abstract

The genus Echinophora (Apiaceae) is represented in the flora of Turkey by six species including three endemics [1]. The plant is also used in folk medicine to heal wounds and to treat gastric ulcers due to its antifungal, carminative, and digestive properties [2]. In previous works, the characteristic compounds of pickling herb oil were methyl eugenol, α-phellandrene, δ-3-carene, and p-cymene [3–7]. In this paper, the composition of pickling herb essential oils of the plants from two years and localities is reported. Two samples of stored essential oil were also included
