摘　　要：[目的]研究油樟[Cinnamomum longepaniculatum(Gamble)N.Chao]叶挥发油乳剂和醑剂的空气消毒效果。[方法]制备稳定的油樟叶挥发油乳剂和醑剂,液体喷雾消毒动物实验房15min,消毒后营养琼脂平板采样30min。37℃培养48h后进行空气中菌落计数。[结果]用浓度为2%、8%和16%的油樟叶挥发油乳剂消毒后空气中菌落数显著少于空气对照(P<0.05),浓度为16%的剂量组细菌平均消亡率达84%;油樟叶挥发油醑剂各剂量组空气中菌落数均极显著少于溶剂对照(P<0.01),浓度为4%的剂量组细菌平均消亡率达91%。不同浓度的2种制剂中4%的醑剂消毒效果最佳。[结论]醑剂整体消毒效果高于乳剂,醑剂中低浓度效果相对较好,可替代84消毒液等其他消毒液。[Objective] The study aimed to evaluate air sterilizing effect of emulsion and spiritus of the volatile oil from the leaf of C.longepaniculatum.[Method]Stable emulsion and spiritus of the volatile oil from the leaf of C.longepaniculatum were got,obtaining the sample 30 min after sterilizing laboratory animal rooms for 15 min by general nutrition agar plate;then counting the bacteria volume separately after incubated for 48 h in 37 ℃.[Result]The significant differentia is existing when comparing the bacteria volume after been sterilized by the 2%,8% and 16% of the emulsion of the volatile oil with not being sterilized（P 0.05）,the 84% of bacillus could be eliminated by the 16% emulsion.The significant differentia is existing when comparing the bacteria volume after been sterilized by the 2%,4% and 8% of the spirit of the volatile oil with not being sterilized（P 0.01）,the 91% of bacillus could be eliminated by the 4% spiritus.4% of the spirit can get the best disinfection effect among the two pharmaceutics of different concentrations.[Conclusion]As a whole,spiritus do better in air sterilizing compared with the emulsion.The spiritus at low concentrations is relatively effective on the system,so disinfections like 84 could be substituted.
