伊朗蒿精油的微波提取及抑菌活性初步研究

Microwave Extraction of Essential Oil from Artemisia persica Boiss and Preliminary Study on Antibacterial Activity

[目的]探讨微波提取伊朗蒿精油的最佳工艺条件,并对精油的抑菌效果进行研究。[方法]采用微波处理方法,试用不同的条件对伊朗蒿精油进行提取,并采用滤纸片扩散法来检测精油的抑菌效果。[结果]伊朗蒿精油的最佳微波提取工艺是:料液比为1∶15(W/V,g/ml,下同),微波湿处理30 min后保持4 h的回流时间;在此条件下,伊朗蒿精油的精油量为11.0 ml/kg。抑菌试验结果表明,伊朗蒿精油对于细菌生长具有明显的抑制作用。[结论]该研究为伊朗蒿的综合利用与开发提供了理论依据。

[ Objective] The research aimed to explore the best conditions of microwave extraction essential oils from Artemisia persica Boiss and the antibacterial effects of essential oils. [ Method ] Try different conditions on oil extraction after microwave treatment, then use filter pa- per diffusion method to detect the inhibitory effect of essential oils. [ Result] The best condition is to keep the ratio of solid to liquid 1： 15, with 30min microwave extraction and the time of reflux is 4h. In this condition, the yield of essential oil is 11. 0 ml/kg. The essential oils of Artemisia persica Boiss is also proved to have the effect of inhibiting the growth of bacteria. [ Conclusion] The research provides the theoretical basis for development and comprehensive utilization of Artemisia persica Boiss.
