Abstract:
Objective To prepare Herba Cistanche enteric release microspheres, optimize the preparation process and study the releasing characteristics of microspheres in vitro.Methods Ion gelatin-oven drying method was used to prepare Herba Cistanche enteric microspheres.The preparation process was optimized with the aid of a Box-Behnken design.Results The optimal preparation condition was 36.33 mg/ml of sodium alginate, 10.82 mg/ml of calcium chloride and 10.93 mg/ml of chitosan.Conclusion This technology is repeatable and feasible.The microspheres have high entrapment efficiency and good sustained release characteristics.
