Essential oil compositions of fresh leaves, flower stems and rhizomes obtained by hydrodistillation from different Croatian populations of Petasites albus (L.) Gaertn. and Petasites hybridus (L.) G.Gaertn., B.Mey. & Scherb. (four of each species) were investigated using gas chromatography-flame ionization detection and gas chromatography-mass spectrometry. Altogether, 118 constituents were identified, accounting for 81.19-96.81 % of total oil composition. All essential oils were characterized by oxygenated sesquiterpenes, with distinct compounds recorded for both investigated species. Clear separation between the two species was confirmed by principal component analysis and hierarchical cluster analysis. This is the first study that recorded intraspecific variations of essential oil constituents from P. albus and P. hybridus. Obtained results could contribute to the understanding of their medicinal and nutritional value.
通过水蒸馏法从克罗地亚不同种群的白蜂斗菜（Petasites albus (L.) Gaertn.）和杂种蜂斗菜（Petasites hybridus (L.) G.Gaertn., B.Mey. & Scherb.）（每个物种各四种）中获取的新鲜叶片、花茎和根茎的精油成分，采用气相色谱 - 火焰离子化检测和气相色谱 - 质谱联用技术进行了研究。共鉴定出118种成分，占总油成分的81.19 - 96.81％。所有精油均以氧化倍半萜为特征，两个研究物种均记录到了不同的化合物。主成分分析和层次聚类分析证实了两个物种之间的明显分离。这是首次记录白蜂斗菜和杂种蜂斗菜精油成分种内变异的研究。所得结果有助于理解它们的药用和营养价值。
