Different parts of Bellis perennis were subjected to hydrodistillation and the products were subsequently analyzed by GC and GC/MS. Aqueous and methanol extracts were prepared from the aerial parts. Antioxidant [1,1-diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging, reducing activity, total antioxidant] and antimicrobial activity of the plant materials were studied. The aqueous extracts showed higher DPPH scavenging activity (85.8% at 102.5 microg/mL) than the methanol extract. Reducing power was also observed for both tested extracts, where the formation of linoleic acid peroxides was more for the aqueous extract than the methanol extract. Antimicrobial activities of all plant materials were evaluated at varying concentrations against a panel of pathogens, but without pronounced inhibitory effect.
对雏菊的不同部位进行水蒸馏，随后通过气相色谱（GC）和气相色谱 - 质谱联用（GC/MS）对产物进行分析。从地上部分制备了水提取物和甲醇提取物。研究了植物材料的抗氧化活性（1,1 - 二苯基 - 2 - 苦基肼自由基清除能力、还原能力、总抗氧化能力）和抗菌活性。水提取物显示出比甲醇提取物更高的DPPH自由基清除活性（在102.5微克/毫升时为85.8%）。两种受试提取物均观察到有还原能力，其中水提取物中亚油酸过氧化物的形成比甲醇提取物更多。在不同浓度下对一组病原体评估了所有植物材料的抗菌活性，但未观察到明显的抑制作用。
