The chemical composition of essential oils from aerial parts of Thymus spinulosus Ten. (Lamiaceae) is reported. Four oils from plants growing in different environmental conditions were characterized by GC and GC-MS methods; the oils seem to indicate a new chemotype in the genus Thymus. Influences of soil and altitude characteristics on the essential oil composition are discussed. The oils showed antibacterial activity against Gram-positive (Staphylococcus aureus, Streptococcus faecalis, Bacillus subtilis, and Bacillus cereus) and Gram-negative (Proteus mirabilis, Escherichia coli, Salmonella typhimuium Ty2, and Pseudomonas aeruginosa) bacteria.
报道了刺叶百里香（唇形科）地上部分精油的化学成分。采用气相色谱（GC）和气相色谱 - 质谱联用（GC - MS）方法对生长在不同环境条件下的植物所提取的四种精油进行了表征；这些精油似乎表明百里香属中存在一种新的化学型。讨论了土壤和海拔特征对精油成分的影响。这些精油对革兰氏阳性菌（金黄色葡萄球菌、粪肠球菌、枯草芽孢杆菌和蜡样芽孢杆菌）和革兰氏阴性菌（奇异变形杆菌、大肠杆菌、鼠伤寒沙门氏菌Ty2和铜绿假单胞菌）均表现出抗菌活性。
