纯胶与β-环糊精2种包合材料的比较
Chinese Journal of Experimental Traditional Medical Formulae（2015）
Abstract
目的:比较纯胶与β-环糊精(β-cyclodextrin,β-CD)的包合效果.方法:以包合率与包合物收率为指标,选取纯胶与β-CD为包合材料,采用高压均质机、磁力搅拌器、超声波细胞破碎仪、超声波清洗器4种方法分别对羌活、连翘、辛夷挥发油进行包合,通过单因素试验优选包合工艺,包合物进行差示扫描量热分析与红外光谱表征.结果:纯胶的包合率明显高于β-CD,包合物收率略低于β-CD.挥发油已被纯胶包合,红外谱图中纯胶包合物的最大吸收峰相对于纯胶有向高频数迁移,表明纯胶包合物为一新生物相,且包合效果稳定.结论:以纯胶为包合材料,采用磁力搅拌法制备包合物的工艺简单且包合效果好.
