摘要:研制一种新型白蒿精油杀菌空气清新剂。传统水蒸气蒸馏法提取白蒿精油,微孔稀释法考察其抑菌活性。
为了提高精油的利用率,采用β环糊精(B-CD)徽胶囊技术对其进行包合,从而研制成新型喷雾空气清新剂,并在
流通的病房考察空气清新剂的消毒效果。结果表明,白蒿精油具有广谱抗菌效果,对实验所用的致病菌有较强的
抑制和灭活作用。对大肠埃希氏菌和白假丝酵母菌的MIC可达7.8uL/mL,MBC值范圃为7.80-60.50wL/mLo
白蒿精油空气清新剂消春效果显著的髙于对照,其杀菌率为85.63%。白蒿精油空气清新剂具有较强的空间灭菌
作用,是一种有效的新型空气消毒剂。

Abstract: The formula of a new type of air disinfectant made from essential oil(EO )of Artemisia aneth
oides Maf. was studied. The essential oil was extracted by traditional steam distillation method and mi-
croplate bioassay was used to evaluate the antibacterial activities of essential oil. In order to improve the
utilization of essential oil, the inclusion complex between -CD-E0 was prepared by blending method and
a new spray air pure and fresh agent was abtained, and the air sanitized effect of the air refreshing agents
was observed in open ward. In the case of antimicrobial activity, the results possessed broad and remarka-
Dle antimicrobial activity against the microorganisms tested containing 10 bacteria, the minimal inhibitor
concentration (MIC) value for bacteria was 7. 8 WL/ml and the minimal bactericidal concentration
(MBC was rom 7. 80 60.50 wll/ml. The pencentage of air-disinfectant effects of air refreshing agents.
