Essential oils from the aerial parts of Anacyclus pyrethrum L. were analysed at three developmental stages (vegetative, floral budding and flowering). Oil yield was found to vary depending on the stage of development, and the highest content of oil (0.019% w/w) was obtained at flowering stage. The chemical composition of essential oils studied by GC and GC-MS showed a total of 91 compounds. Whatever the analysed stage is, oxygenated sesquiterpenes were the most abundant group. Their level significantly increased during ripening and varied from 37.1% to 58.6%. The oil showed activity against Candida albicans and Staphylococcus aureus bacteria strains. Thus, they represent an inexpensive source of natural antibacterial substances that may potentially be used in pathogenic systems.
从蓝蓟地上部分提取的精油在三个发育阶段（营养生长、花蕾形成和开花期）进行了分析。发现油产量随发育阶段而变化，在开花期获得了最高的油含量（0.019%w/w）。通过 GC 和 GC-MS 研究的精油化学成分共鉴定出 91 种化合物。无论分析的阶段如何，含氧倍半萜都是最丰富的一类。它们的水平在成熟过程中显著增加，从 37.1%到 58.6%不等。该油对白色念珠菌和金黄色葡萄球菌的细菌菌株具有活性。因此，它们代表了一种廉价的天然抗菌物质来源，可能在病原系统中得到应用。
