目的：考察主要成膜材料在龙血竭乙醇溶液中的成膜性能，为含龙血竭中药涂膜剂成膜材料的选择提供参考。方法选择聚乙烯醇(PVA124、1788)，聚乙烯吡咯烷酮(PVP￣K30)，乙基纤维素(EC)，甲基纤维素(MC)，聚乙烯醇缩丁醛(PVB)等成膜材料，从溶解性、成膜时间、是否易脱膜等几个方面综合考察各成膜材料在龙血竭乙醇溶液中的成膜性能。结果 PVA1788与 PVP￣K30按4：1的比例混合在龙血竭乙醇溶液中具有较好的成膜性，且膜质地光滑、均匀、易脱膜；PVA124与 PVP￣K30按4：1的比例混合后在龙血竭乙醇溶液中会有沉淀析出；EC、MC、PVB 等成膜材料作基质不易脱膜。结论 PVA1788与 PVP￣K30按4：1比例混合，再加入丙二醇，是含龙血竭的中药涂膜剂成膜材料的最优选择。

Objective To study the film￣forming property of film￣forming materials in dragon blood ethanol solution, and provide the reference for screening of film￣forming materials for dragon blood plastics. Methods PVA124,PVA1788, PVP￣K30, EC, MC, PVB were chosen to study the film￣forming property of film￣forming materials based on solubility, formation time, and adhesion. Results PVA1788 and PVP￣K30 mixed in dragon blood ethanol solution in proportion of 4:1 showed good film￣forming property, and the membrane was smooth, uniform and easy to tear off.However, PVA124 and PVP￣K30 mixed in proportion of 4:1 precipitated in dragon blood ethanol solution.EC, MC and PVB were not easy to tear off the membrane. Conclusion PVA1788 and PVP￣K30 mixed in proportion of 4:1 and added with propylene glycol is the optimal choice of film￣forming material for dragon blood spray film.
