摘　　要：利用固体颗粒(复合纳米颗粒)稳定油水界面的特性,制备玉米醇溶蛋白-虾青素纳米颗粒(Zein-AST NPs)和玉米醇溶蛋白-虾青素-阿拉伯胶复合纳米颗粒(Zein-AST-GA NPs),并比较它们的稳定性差异。以Zein-AST-GA NPs为稳定剂,使用含AST的玉米油制备Pickering乳液,研究乳液中AST的稳定性、体外释放率和大鼠体内药代动力学。实验结果显示:油相中含有AST的Pickering乳液(PE1)比油相中不含AST的Pickering乳液(PE2)具有更好的热稳定性和贮藏稳定性,且PE1具有较强的自由基清除能力,释放速率优于参比制剂和PE2,AST的释放符合菲克扩散规律;口服PE1后8 h达到最大AST血浆质量浓度(2.654μg·mL^(-1)),且相对生物利用度分别是市售虾青素微囊粉(AST-MCs)和PE2的1.703,1.481倍。The property of solid particles(composite nanoparticles)to stabilize the oil water interface was utilized to prepare corn zein solubilized protein astaxanthin nanoparticles(Zein AST NPs)and corn zein solubilized protein astaxanthin arabic gum composite nanoparticles(Zein AST GA NPs),and their stability differences were compared.Using Zein AST GA NPs as stabilizer,Pickering emulsion was prepared using corn oil containing AST.The stability,in vitro release rate,and in vivo pharmacokinetics in rats of AST in the emulsion were studied.The experimental results show that the Pickering emulsion containing AST(PE1)in the oil phase has better thermal and storage stability than the Pickering emulsion without AST in the oil phase(PE2),and PE1 has stronger free radical scavenging ability with a release rate superior to that of the reference formulation and PE2,and the release of AST is in accordance with Fick′s diffusion law.The maximum AST plasma mass concentration(2.654μg·mL^(-1))is reached 8 hours after oral administration of PE1,and the relative bioavailability are 1.703 and 1.481 times higher than that of commercially available astaxanthin microcapsule powder(AST MCs)and PE2,respectively.
