Abstract

The main aim of this study was to assess the differences in the chemical composition of essential oil from biocultivated Lavandula angustifolia in the Thracian Lowland floristic region, Bulgaria, and commercially available products from Bulgarian markets. Following the analytical results conducted with gas chromatography-mass spectrometry, we have established some differences in the chemical composition of the tested samples. The essential oil of biocultivated lavender contained 35 compounds, which represent 94.13% of the total oil. Samples from commercial products contained 28-42 compounds that represent 93.03-98.69% of the total oil. All the examined samples were rich in monoterpene hydrocarbons (1.68-12.77%), oxygenated monoterpenes (70.42-87.96%), sesquiterpene hydrocarbons (4.03-13.78%), and oxygenated sesquiterpenes (0.14-0.76%). The dominant components in all examined samples were linalool (20.0-45.0%) and linalyl acetate (20.79-39.91%). All the examined commercial samples contained linalool and linalyl acetate as was described in the European Pharmacopoeia, but in one of the samples, the quality of linalyl acetate is lower than that recommended in the European Pharmacopoeia.

商品薰衣草精油与人工栽培薰衣草精油化学成分比较。

本研究的主要目的是评估保加利亚色雷斯低地植物区生物栽培的薰衣草精油和保加利亚市场上可买到的薰衣草精油化学成分的差异。根据气相色谱-质谱分析结果，我们确定了被测样品在化学成分上的一些差异。生物栽培薰衣草精油中含有35种化合物，占总挥发油的94.13%。商业产品样品中含有28-42种化合物，占总油的93.03-98.69%。所有样品均富含单萜烃(1.68 ~ 12.77%)、氧合单萜烃(70.42 ~ 87.96%)、倍半萜烃(4.03 ~ 13.78%)和氧合倍半萜烃(0.14 ~ 0.76%)。主要成分为芳樟醇(20.0 ~ 45.0%)和乙酸芳樟醇(20.79 ~ 39.91%)。所有经检查的商业样品均含有欧洲药典中所述的芳樟醇和醋酸芳樟醇，但其中一个样品中醋酸芳樟醇的质量低于欧洲药典的推荐质量。
