ABSTRACT Chemical composition of the essential oils of three subspecies of Algerian Thymus munbyanus Boiss. & Reut. (subsp. abylaeus, subsp. ciliatus and subsp. coloratus) aerial parts have been investigated. GC and GC/MS analysis allowed the identification of sixty-eight compounds accounting for 99.3%, 99.7% and 98.2% of collective essential oils of three subspecies. The main components of three collective essential oils were: α-terpinyl acetate (51.7%), α-terpineol (9.7%), borneol (6.8%) and bornyl acetate (5.2%) for subsp. abylaeus; carvacrol (65.7%), γ-terpinene (13.6%) and p-cymene (7.9%) for subsp. ciliatus and camphor (25.9%), myrcene (16.9%), 1,8-cineole (6.5%) and camphene (6.2%) for subsp. coloratus. Intra-species variations of chemical compositions of essential oil from thirty-five Algerian samples were also investigated using statistical analysis. Essential oils samples were discriminated in three main clusters confirming relation between the chemical compositions and taxonomical differentiation between the three subspecies. These results confirm chemotaxonomic differentiation of all subspecies of T. munbyanus.

Thymus munbyanus Boiss 三个亚种精油的化学变异性。& 回复。来自阿尔及利亚西部

摘要 阿尔及利亚百里香三种亚种精油的化学成分。& 回复。（亚种 abylaeus、亚种 ciliatus 和亚种 coloratus）地上部分已被调查。GC 和 GC/MS 分析可以鉴定出 68 种化合物，分别占三个亚种集体精油的 99.3%、99.7% 和 98.2%。三种集体精油的主要成分是：α-松油醇乙酸酯（51.7%）、α-松油醇（9.7%）、冰片（6.8%）和乙酸冰片酯（5.2%）。阿比拉乌斯；香芹酚 (65.7%)、γ-萜品烯 (13.6%) 和对伞花烃 (7.9%) 用于亚种。亚种的纤毛和樟脑 (25.9%)、月桂烯 (16.9%)、1,8-桉树脑 (6.5%) 和莰烯 (6.2%)。彩蝶。还使用统计分析研究了来自 35 个阿尔及利亚样品的精油化学成分的种内变化。精油样品分为三个主要簇，确认了三个亚种之间的化学成分和分类学差异之间的关系。这些结果证实了 T. munbyanus 的所有亚种的化学分类学分化。
