[ Objective ] Data were provided to further breed improvement and industry development by analyzing composition and content of essential oil from three lavender varieties. [ Method ] Firstly, the essential oil was respectively extracted from lavender inflorescence by steam distillation using NKS-L1, H-701, XDT-5. Then, the compositions and content of essential oil were analyzed by gas chromatography-mass spectrometry. [Result] The essential oil content of XDT-5 was the highest, followed by H-701, and NKS-L1 is the lowest. In addition, the essential oil composition of NKS-L1, H-701, XDT-5 were identified 35, 43 , 38 compounds, respectively. The aroma components mainly included linalool and linalyl acetate. [ Conclusion] There were significant difference of chemical component and the essential oil content among three lavender varieties.%[目的]分析新疆地区3个品种薰衣草的精油成分及含量差异,为薰衣草进一步的品种改良及产业发展提供数据.[方法]以NKS-L1、H-701、XDT-5 3个薰衣草品种为研究对象,首先用水蒸气蒸馏法从花穗中提取精油,然后借助气相-质谱联用仪(GC-MS)检测分析其精油化学成分.[结果]XDT-5精油含量最高,其次为H-701,NKS-L1最低.从NKS-L1、H-701、XDT-5中分别鉴定出35、43、38种组分,主要成分为芳樟醇、乙酸芳樟酯.[结论]新疆薰衣草品种间精油成分及含量存在显著差异.
