The essential oils of air-dried Centaurea sessilis and Centaurea armena obtained by hydrodistillation were analyzed by gas chromatography-mass spectrometry (GC-MS). Forty and twenty components were identified in the essential oils and the main component of these taxons was beta-eudesmol in the ratios of 12.4% and 19.3% from C. sessilis and C. armena, respectively. The antimicrobial activity of the isolated essential oil of the plants was also investigated. They showed moderate antibacterial activity against Gram-positive and Gram-negative bacteria, but no antifungal activity was observed against two yeastlike fungi.
采用水蒸气蒸馏法从风干的无茎矢车菊和亚美尼亚矢车菊中提取挥发油，并通过气相色谱-质谱联用（GC-MS）对其进行分析。在挥发油中分别鉴定出40种和20种成分，这些分类群的主要成分是β-桉叶醇，在无茎矢车菊和亚美尼亚矢车菊中的占比分别为12.4%和19.3%。还研究了从这些植物中分离得到的挥发油的抗菌活性。它们对革兰氏阳性菌和革兰氏阴性菌表现出中等程度的抗菌活性，但对两种类酵母真菌未观察到抗真菌活性。
