Preparation of oryzanol-chitosan microcapsules
摘要
Abstract
BACKGROUND:Chitosan has a good biocompatibility and biodegradability; it can be used as excellent drug controlled release and targeting vector, mucosal absorbent, absorption enhancers. However, the oryzanol sustained-release formulation as well as related literature has not been reported on the market.OBJECTIVE:To investigate the preparation of oryzanol-chitosan microcapsules.METHODS:Oryzanol-chitosan microcapsules were prepared by using of self-made centrifugal sieve granulator under the guidance of coagulation method, and the drug loading and encapsulation efficiency were investigated.RESULTS AND CONCLUSION:The microcapsules were in uniform size, good finish and shape, drug loading of 47.68%,entrapment efficiency of 76.45% . The coagulation method is simple, stable and good reproducible. The results show that it is practicable to encapsulate oryzanol by using of natural polymer polysaccharide chitosan. The oryzanol-chitosan microcapsules have further development and application value.关键词
