The essential oils from four samples of Teucrium lusitanicum and one sample of Teucrium algarbiensis, grown in Algarve (southern Portugal) were analyzed by gas chromatography (GC) and gas chromatography-mass spectroscopy (GC-MS). Seventy-one volatile compounds were identified. Major compounds of T. algarbiensis oil were alpha-pinene (8.3%), sabinene (7.2%), beta-pinene (10.2%), limonene (11.8%) and germacrene D (7.6%). Concerning T. lusitanicum, some quantitative differences were found with regards to the major constituents of the oils from four populations: alpha-pinene (0.8-8.5%), sabinene (2.1-9.6%), beta-pinene (2.5-11.9%), limonene (1.2-11.5%) and elemol (2.6-12.0%).
对生长于葡萄牙南部阿尔加维地区的4个葡萄牙石蚕样本和1个阿尔加维石蚕样本的精油进行了气相色谱（GC）和气相色谱 - 质谱联用（GC - MS）分析。共鉴定出71种挥发性化合物。阿尔加维石蚕油的主要成分是α-蒎烯（8.3%）、桧烯（7.2%）、β-蒎烯（10.2%）、柠檬烯（11.8%）和吉玛烯D（7.6%）。对于葡萄牙石蚕，在来自四个种群的油的主要成分方面发现了一些定量差异：α-蒎烯（0.8 - 8.5%）、桧烯（2.1 - 9.6%）、β-蒎烯（2.5 - 11.9%）、柠檬烯（1.2 - 11.5%）和榄香醇（2.6 - 12.0%）。
