摘　　要： 本文采用水蒸气蒸馏法和溶剂提取法提取板蓝根油,并对提取物进行抗菌测试。通过明胶-阿拉伯胶复凝聚法制备板蓝根挥发油微胶囊,并对影响微胶囊形貌的因素进行初步探讨。结果表明,两种方法所提取的板蓝根挥发油的抗菌效果达到高敏程度;板蓝根挥发油微胶囊制备条件在壁材系统浓度为1.0%、复凝与固化搅拌速度为400 r/min时,所得微胶囊分散性良好、球形规则,且微胶囊的最高载药量与最高包封率分别为23.68%、60.85%。本文制得的板蓝根挥发油微胶囊,为深度挖掘板蓝根的利用价值提供了一种新的途径和方法。 In this study,essential oil extracted from Radix was obtained by steam distillation and solvent extraction,and its antimicrobial testing was carried out.Microcapsules of essential oil from Radix were prepared by coacervation of gelatin-acacia complex and the factors that affect the morphology of microcapsules were discussed.The results showed that the essential oil extracted from Radix by both techniques has excellent antibacterial ability.The conditions of preparation microcapsules of essential oil from radix were： the concentration of wall material 1.0% and complex coacervation and solidify stirring speed of 400 r/min.Under these conditions,the microcapsules of essential oil were well dispersed.The highest microencapsulated drug loading and highest encapsulation efficiency were 23.68% and 60.85% respectively.The research provided a new method to use Radix.
