Determination of Essential Oil Yields and Composition Lavender and Lavandin Cultivars (Lavandula sp.) Cultivated in Tuzlukçu, Konya

Abstract

Lavender is an important medicinal plant, which used in many fields such as perfumery, cosmetics, medicine, aromatherapy and phytotherapy thanks to its high quality essential oils components. Hemus and Sevtapolis lavender cultivars of Lavandula angustifolia and Super A lavandin of Lavandula x intermedia were used in the study. The lavenders and lavandin were planted in 2022 in Tuzlukçu district of Konya province and harvested in 2023. Essential oils were obtained from the dried flowers of the plant. The essential oil components of the plant materials were measured by GC-MS. The essential oil yield of Lavandula angustifolia cv. Hemus was 2.65%, that of Lavandula angustifolia cv. Sevtapolis was 2.14% and that of Lavandula x intermedia cv. Super A was 7.95%. In the Hemus cultivar of lavender, the concentration of linalyl acetate was 19.76%, linalool was 39.09%, and camphor, an undesired component in lavender essential oil, amounted to 0.41%. Meanwhile, the Sevtapolis cultivars contained 10.64% linalyl acetate, 40.41% linalool and 0.47% camphor. In Lavandin (Super A) cultivar contained 30.39% linalyl acetate, 30.29% linalool, and 6.71% camphor.
