Abstract

In the study, the influence of distillation time as well as distillation apparatus on the chemical composition and quality of lavender (Lavandula angustifolia Mill.) essential oil were investigated. Two different types of distillation apparatuses: Deryng (popular in Poland) and Clevenger-type (recommended by European Pharmacopoeia) were used for the isolation of the essential oil from dried lavender flowers (Lavandulae flos). Moreover, different distillation times (2, 3 and 4 hours) were also applied. The chemical composition of the isolated oils, determined by gas chromatography coupled with mass spectrometry (GC-MS), revealed the dominance of linalool (11.55–17.19%) and linalyl acetate (12.84–16.78%) in the all analyzed samples. Other important constituents were: caryophyllene oxide (5.66–7.35%), lavandulyl acetate (4.64–5.40%) and borneol (4.62–5.51%). On the basis of the obtained data it was proved that the distillation time and distillation apparatus affect the amounts of some constituents in the lavender oil.

蒸馏时间和蒸馏设备对磨坊薰衣草精油化学成分和质量的影响

本研究调查了蒸馏时间和蒸馏设备对薰衣草（Lavandula angustifolia Mill.）精油化学成分和质量的影响。两种不同类型的蒸馏设备：从干薰衣草花（Lavandulae flos）中分离精油时，使用了 Deryng 型（波兰流行）和 Clevenger 型（欧洲药典推荐）。此外，还采用了不同的蒸馏时间（2、3 和 4 小时）。通过气相色谱-质谱法（GC-MS）测定分离出的精油的化学成分，发现芳樟醇（11.55%-17.19%）和乙酸芳樟酯（12.84%-16.78%）在所有分析样品中占主导地位。其他重要成分包括：氧化香叶醇（5.66-7.35%）、乙酸拉旺杜酯（4.64-5.40%）和龙脑（4.62-5.51%）。根据获得的数据证明，蒸馏时间和蒸馏设备会影响薰衣草精油中某些成分的含量。
