| 摘 要： | 采用壳聚糖为基材、果胶为交联剂制备了薄膜材料，考察了卡拉胶和淀粉为添加剂对该薄膜材料力学性能的影响。结果显示，不加卡拉胶、淀粉的果胶-壳聚糖复合聚合物薄膜材料由于不溶于模拟胃液和模拟肠液，不适合单独作为缓释胶囊材料。当加入卡拉胶和淀粉后，不仅可进一步增加薄膜材料的柔韧性、凝胶性、透明度和力学性能，还增加其在模拟肠液和胃液中的溶解性。果胶-壳聚糖、卡拉胶、淀粉的质量比为2∶1∶1，得到的薄膜材料不仅具有良好的成型性和弹性，也具有适中的胃液和肠液溶解性。将该材料制备成胶囊，在模拟胃液和模拟肠液环境考察其破壁缓释效果，结果显示，胶囊在模拟胃液和肠液中的溶解是一个缓慢过程，浸泡6h后，胶囊药物的缓释率大致为93%。 |

| Abstract: | Films material was prepared through crosslinking of chitosan and pectin. The effects of carrageenan and starch as additives on the mechanical properties of the films were investigated. The results showed that the pectin-chitosan composite membrane material without carrageenan and starch was not suitable to be used as sustained-release capsule material alone because it was insoluble in simulated gastric solution and intestinal solution. When carrageenan and starch were added, the flexibility, gelatinization, transparency and mechanical properties of the films were further improved, and the solubility of the films in simulated intestinal and gastric solution was increased. When chitosan-pectin∶carrageenan∶starch had a mass ratio of 2∶1∶1, the film material not only had good formability and elasticity, but also had moderate solubility in gastric solution and intestinal solution. The results of the capsule degradation showed that the capsule dissolution was a slow process in the simulated gastric solution and intestinal solution, and the sustained release rate of the capsule was about 93% after 6h immersion. |
| Keywords: | chitosan capsule material pectin carrageenan sustained release |
