摘要:以乙基纤维素为囊材,采用物理化学法制备蜂胶微囊。对蜂胶微囊的形态、粒径分布、释放性能等进行了研究。该法所制蜂胶-乙基纤维素微囊圆整度好,并具有较好的缓释性能。溶出曲线和微囊形貌结构照片研究表明,可能至少存在两种不同的溶出释放通道。
Ethylcellulose (EC) was used as wall materials to prepare EC-propolis microcapsules, by the physical chemistry method. Their morphology, size distribution, and release behavior were measured. The circularity and sustained-release behavior of the resulted microcapsules were both better. With the studies of release curves and SEM photos of the microcapsules, it was shown that two kinds of release profile might exist at least.
