艾叶挥发油体外抗菌作用研究

Antimicrobial activities of volatile oil from Folium Artemisiae Argyi

采用水蒸汽蒸馏提取艾叶挥发油,得到淡黄色艾叶挥发油,提取率为0.65%。用1%吐温-80乳化得到的艾叶挥发油乳剂。该乳剂稳定性好,安全可行。体外抑菌试验结果表明,艾叶挥发油对炭疽杆菌抑制作用最强,对金黄色葡萄球菌和大肠杆菌也有较强的抑菌作用,但对巴氏杆菌、链球菌、沙门氏菌的抑菌效果不明显;艾叶挥发油对水生生物常见病原菌大肠埃希氏菌、荧光假单胞菌、嗜水气单胞菌、产酸克雷伯菌、鱼害黏球菌、副溶血菌均有较好的抑菌效果。

Volatile oil was extraeted from Folium Artemisiae Argyi by using steam distillation with extracting efficiency of 0.65%. The oil was emulsified by 1% Twain 80. The emulsion stability was good, safe and feasible. In vitro antibacterial experiment results demonstrated that volatile oil from Folium Artemisiae Argyi had best inhibition effect against Bacillus anthracis, the second strongest effect against Staphylococcus aureus and Escherichia coli, but had no obvious inhibition against Pasteurella, Streptococcus and Salmonella.Volatile oil from Folium Artemisiae Argyi had antimierobial activities against aquatic pathogenic bacteria such as Escherichia coli ,Pseudomonas fluorescens ,Aeromonas hydrophila, Klebsiella oxytoca , Myxococcus pisciocola and Vibrio parahaemolyticus.
