The water-distilled essential oil the leaves of Coridothymus capitatus were analyzed by GC/MS and also analyzed by direct thermal desorption GC/MS. Comparison was made between two analyses techniques. The essential oil consisted mainly of monoterpenes 98.9%, while oxygenated hydrocarbons were identified as 55.6 % and non-oxygenated hydrocarbons as 43.6%. As major components were found carvacrol (35.6%), p-cymene (21.0%), thymol (18.6%), gamma-terpinene (12.3%), alpha-terpinene (3.2%), beta-myrcene (3.0%) and alpha-thujene (1.3%) by hydrodistillation and by the GC/MS method. The direct thermal desorption GC/MS analysis also showed the same major components, namely carvacrol (51.6%), thymol (21.7%), p-cymene (9.7%) gamma-terpinene (8.2%), alpha-terpinene (1.64%). The essential oil of C. capitatus showed strong activity against S. aureus, P. vulgaris, P. aeruginosa, E. coli, K. pneumonia, B.
采用气相色谱/质谱联用仪（GC/MS）对头状百里香叶的水蒸馏精油进行了分析，并通过直接热解吸GC/MS进行了分析。对两种分析技术进行了比较。该精油主要由单萜类化合物组成（98.9%），其中氧化烃类占55.6%，非氧化烃类占43.6%。通过水蒸馏和GC/MS方法，发现主要成分有香芹酚（35.6%）、对伞花烃（21.0%）、百里香酚（18.6%）、γ-萜品烯（12.3%）、α-萜品烯（3.2%）、β-月桂烯（3.0%）和α-侧柏烯（1.3%）。直接热解吸GC/MS分析也显示了相同的主要成分，即香芹酚（51.6%）、百里香酚（21.7%）、对伞花烃（9.7%）、γ-萜品烯（8.2%）、α-萜品烯（1.64%）。头状百里香精油对金黄色葡萄球菌、普通变形杆菌、铜绿假单胞菌、大肠杆菌、肺炎克雷伯菌、芽孢杆菌表现出较强的活性。
