Lavandula angustifolia ve L. intermedia Türlerinin Hasat Sonrası Kuruma Sürelerinin Uçucu Yağlarının Kimyasal Bileşenleri Üzerindeki Etkileri

Abstract

This study reported the chemical composition of essential oils of Lavender (L. angustifolia subs. angustifolia) and Lavandin (Lavandula x intermedia var. Super A). GC and GC/MS analyses were used for the identification of essential oils. The essential oils from fresh and air-dried aerial parts of Lavender and Lavandin were obtained by hydrodistillation method. In total, 49, 51, 50 and 40 constituents were identified and quantified in the essential oils of L. angustifolia (fresh and air-dried aerial parts) and L. intermedia (fresh and air-dried aerial parts) respectively. The major components of essential oils of L. angustifolia (fresh), L. angustifolia (air-dried aerial parts), L. intermedia (fresh) and L. intermedia (air-dried aerial parts) were 1,8-cineole (12.65%, 10.15%, 12.74%, 2,28%), linalool (38.31%, 37.94%, 38.10%, 47.47%), camphor (13.74%, 12.52%, 7.61%, 6.67%), borneol (6.82%, 7.16%, 6.84%, 4.64%). While the 1,8 cineole (12.65%, 10.15%) concentration decreased with the post-harvest drying process, the linaly acetate (1.02%, 2.80%) concentration increased in the essential oils of fresh and air-dried aerial parts of L. angustifolia. This study provides evidence that there is a change in essential oil components with post-harvest drying. Thus, it was concluded that the essential oil of the plant can be obtained by distillation of fresh and air-dried aerial plants after the harvest, considering the desired compound ratio.
