Lavender, otherwise known as Mill., is widely used in landscaping, and its oil is a valuable raw material used in many industries. Therefore, new varieties of this plant are bred. The essential oil composition obtained from fresh flowers of thirteen new Ukrainian cultivars of were analysed by GC-MS, and eighty-two components were identified. Linalool and linalyl acetate were principal constituents of all of the samples, and ranged from 11.4% to 46.7% and 7.4% to 44.2%, respectively. None of the studied samples fulfilled the requirements of Ph. Eur. and ISO 3515:2002. The main reason was a high content of -terpineol (0.5-4.5%) and/or terpinene-4-ol (1.2-18.7%). Our results are in line with multiple researchers showing that the studied lavender oils do not comply with the industry standards despite their authenticity. We also investigated the effect of the growth year on the chemical composition of five tested cultivars grown on the same plots and noticed a considerable variability between years. The obtained experimental data did not show a significant inter-year trend for the content changes of the major components. Our results allow us to deeply characterize the new cultivars and evaluate their oil for a possible use in the industry, or to designate them for future selective breeding.
薰衣草，也称为 Mill.，广泛用于园林景观，其精油是许多行业的宝贵原材料。因此，这种植物的新品种被培育出来。通过 GC-MS 对 13 种新的乌克兰薰衣草品种的新鲜花朵获得的精油成分进行了分析，鉴定出了 82 种成分。芳樟醇和乙酸芳樟酯是所有样品的主要成分，分别在 11.4%至 46.7%和 7.4%至 44.2%的范围内。在所研究的样品中，没有一个符合 Ph. Eur. 和 ISO 3515:2002 的要求。主要原因是 -萜品醇（0.5-4.5%）和/或萜品-4-醇（1.2-18.7%）含量高。我们的结果与多位研究人员的结果一致，表明尽管薰衣草油是真实的，但它们不符合行业标准。我们还研究了生长年份对在相同地块种植的五个测试品种化学成分的影响，发现年份之间存在相当大的可变性。获得的实验数据显示，主要成分含量变化没有明显的年际趋势。我们的结果允许我们深入描述新品种，并评估它们的油是否有可能用于工业，或指定它们用于未来的选择性繁殖。
