目的:提取含笑花、紫玉兰花、栀子花、藿香花以及蔷薇花中的挥发性物质,探讨这5种花挥发性物质的抗氧化活性和抗菌活性为其开发利用可提供科学依据。方法:用水蒸气蒸馏法从含笑花、紫玉兰花、栀子花、藿香花以及蔷薇花中分别提取挥发性物质,测定其对羟基自由基的清除作用来确定抗氧化活性效果,测定最小抑菌浓度(MIC)和最小杀菌浓度(MBC)来确定这5种花挥发性物质的抗菌活性。结果:5种花的挥发性物质均有明显的抗氧化活性,这5种花的挥发性物质均具有显著地抗菌活性。结论:这5种花的挥发性物质抗氧化活性大小依次为含笑花﹥藿香花﹥紫玉兰花﹥栀子花﹥蔷薇花;抗菌活性大小依次为藿香花﹥紫玉兰花﹥蔷薇花﹥栀子花﹥含笑花。
OBJECTIVE: To extract the volatile compounds of Lilac flower, Purple magnolia flower, Gardenia flower, Agastache rugosa and Rose flower, and to explore the antioxidant and antibacterial activities of these 5 species of flower volatiles to provide a scientific basis for their development and utilization. Methods: Volatile compounds were isolated from Lilac flower, Purple magnolia flower, Gardenia flower, Agastache rugosa, and Rosa rugosa by steam distillation. The scavenging effect on hydroxyl radical was measured to determine the antioxidant activity. The minimum inhibitory concentration Concentration (MIC) and minimum bactericidal concentration (MBC) to determine the antibacterial activity of these five kinds of flower volatiles. Results: All five kinds of flowers volatile substances have obvious antioxidant activity, these five kinds of flower volatile substances have significant antibacterial activity. Conclusion: The antioxidant activities of the volatile components of the five species of flowers are as follows: Lathyrus> Ageratum> Ageratum> Gardenia> Rose; the order of antibacterial activities is Ageratum, Violaceae, > Smiley flower.
