摘　　要：以艾蒿油为芯材,壳聚糖和阴离子型乳化剂为壁材,采用复凝聚法制备壳聚糖-艾蒿微胶囊抗菌剂,探讨了微胶囊合成的主要影响因素:芯壁比、pH值、系统浓度和交联剂用量;拟定单因素试验,优化出了最佳合成工艺条件:系统浓度1%～1.5%,芯壁比为2:1,pH值为6.0,复凝聚反应温度为40℃,交联剂用量为壳聚糖的2%,交联时间为60～90min,得到的壳聚糖微胶囊的外观规整圆滑,平均粒径2～4μm,分布较集中,而且分散均匀。The Chitosan-Artemisiaargyllem microcapsule antibacterial reagent was prepared by complex coacervation, with artemisiaargyllem as core material, chitosan and anion-emulsification reagent as shell material. The main factors affecting the form of microcapsule, including ratio of shell/core materials, pH value, system concentrations and dosage of cross linking reagent, were investigated. Finally, the optimum process for the reaction was obtained through the single factor experiment as： system concentrations of 1.0% to 1.5%, ratio of shell/core materials of 2： 1, pH value 6.0, complex coacervation temperature 40℃, dosage of cross linking reagent 2.0% of chitosan, and cross linking time 60 to 90 min. Microcapsulations prepared in this condition have regular and round appearance with average particle size about 2 to 4μm, narrow size distribution and uniform dispersal,
