Abstract The essential oil isolated from aerial parts of Hypericum rumeliacum Boiss. was analyzed by GC and GC/MS. Forty three identified compounds accounted for 98.8 % of the total oil. The main components of the oil were: (E)-β-ocimene (18.2 %), β-pinene (14.7 %), (Z)-β-ocimene (13.0 %), dodecanal (7.4 %) germacrene D (5.8 %) and myrcene (5.8 %). The volatile profile of H. rumeliacum was characterized by a large content of monoterpene hydrocarbons (68.2 %), followed by non-terpenoids (14.4 %) and sesqiuterpenoids (11.8 %). Multivariate statistical analyses (agglomerative hierarchical cluster analysis and principal component analysis) were used to compare and discuss interrelationship within the mentioned species based on essential oil profiles. The oil was tested in a broth microdilution assay against five bacterial and two fungal strains and found to have mainly moderate antimicrobial effects.

金丝桃地上部分精油的化学成分、抗菌活性和化学分类学。物种

摘要 从金丝桃地上部分分离得到的精油。GC 和 GC/MS 分析。43 种确定的化合物占总油量的 98.8%。该油的主要成分为:(E)-β-罗勒烯 (18.2 %)、β-蒎烯 (14.7 %)、(Z)-β-罗勒烯 (13.0 %)、十二醛 (7.4 %) 锗烯 D (5.8 %) ) 和月桂烯 (5.8%)。H.rumeliacum 的挥发性特征的特点是单萜烃含量高 (68.2%),其次是非萜类化合物 (14.4%) 和倍半萜类化合物 (11.8%)。多变量统计分析(凝聚层次聚类分析和主成分分析)用于根据精油概况比较和讨论上述物种内的相互关系。
