Results: The prepared AmB-PBCA nanoparticle had a regular spherical or elliptic surface, with a mean diameter of (69.01±28.56) nm. The curve of standard AmB was linear within the range of 1.12-5.60μg/ml: D405=0.1634c+0.0066 (r=0.9993). The average recovery of AmB-PBCA-NP was 99.93%, showing the solution of AmB-PBCA-NP was stable within 12 h. The nanoparticles showed a sustained drug release in vitro within 24 h. The optimized recipe was: DextranT-70 stabilizer without sodium deoxycholate, with a mean encapsulation rate of 56.10% and a drug loading rate of 82%.

结果：制备的AmB-PBCA-NP外观呈圆或类圆形，平均粒径(69.01±28.56)nm，分散均匀；AmB标准品在1.12~5.60μg/ml范围内的线性回归方程为：D405=0.1634c+0.0066，r=0.9993，AmB-PBCA-NP的平均回收率为99.93%，其溶液在12h内稳定性较好；体外释放实验表明24h体外释放具有一定的缓释性；实验发现最优化的处方为稳定剂采用DextranT-70，且不加助溶剂脱氧胆酸钠，其包封率及载药量均比较高，分别为56.10%、82%。
