The essential oils of Centaurea pulcherrima Willd. var. pulcherrima (Asteraceae) were isolated by hydrodistillation (HD) and a microwave distillation (MD), than characterised by GC-FID and GC-MS. A total of 58 and 57 compounds were identified, constituting over 93.7%, and 91.6% of volatile oil composition of C. pulcherrima var. pulcherrima, respectively. Sesquiterpene hydrocarbons were shown to be the main group of constituents (HD: 42.4% versus MD: 51.5%). The major component of the oils of C. pulcherrima var. pulcherrima was germacrene D (HD, 17.8% versus MD, 23.2%). The antimicrobial activity of the isolated essential oils of the plant was also investigated, and they showed good antibacterial activity against to tested gram-positive bacteria, especially to M. smegmatis and a yeast-like fungus C. albicans.
金光菊(菊科)的精油通过水蒸馏(HD)和微波蒸馏(MD)进行分离,然后通过 GC-FID 和 GC-MS 进行鉴定。共鉴定出 58 种和 57 种化合物,分别构成 C. pulcherrima var. pulcherrima 挥发油成分的 93.7%和 91.6%。倍半萜烃被证明是主要的成分组(HD:42.4%对 MD:51.5%)。油的主要成分是 germacrene D(HD,17.8%对 MD,23.2%)。还研究了植物分离精油的抗菌活性,它们对测试的革兰氏阳性菌,特别是对 M. smegmatis 和酵母样真菌 C. albicans 表现出良好的抗菌活性。
