目的优化β-榄香烯聚氰基丙烯酸正丁酯纳米粒的制备工艺。方法以聚氰基丙烯酸正丁酯(polybutylcyanoacrylate,PBCA)为载药材料,采用界面缩聚法,以包封率为考察指标,通过单因素试验及正交试验设计优化制备工艺。结果该工艺条件下制得的纳米粒,形态规整,无黏连,大小较为均匀,平均粒径254 nm,平均包封率90.17%。结论本实验优化的制备工艺稳定可行。

Objective Optimizing the formula and preparation of β-elemene-polybutylcyanoacrylate nanoparticles(β-ELE-PBCA-NP).Methods With polybutylcyanoacrylate(PBCA) as the drug-loaded material,β-ELE-PBCA-NP was prepared by interfacial polycondensation.The preparation conditions were optimized by single factor design and the formula was optimized by orthogonal design with entrapment efficiency(EE) as index.EE of β-ELE-PBCA-NP was determinated by RP-HPLC.Results Under the optimal conditions,the prepared NPs were round and regular in shape without adhesions with average particle size of 254 nm and EE of 90.17%.Conclusion The optimized technology in this experiment is stable and feasible.
