1、胃肠宁胶囊的制备工艺研究摘要: 目的 建立胃肠宁提取液中东莨菪内酯的HPLC含量测定的方法,通过L9(34)正交试验,对胃肠宁胶囊的制备工艺进行研究,优选胃肠宁胶囊的制备工艺。方法 根据胃肠宁处方的功能主治和药物成分的性质,采用常用的水提醇沉法提取,建立胃肠宁提取液中东莨菪内酯的HPLC含量测定的方法,通过L9(34)正交试验,以干膏得率和提取液中东莨菪内酯的含量为评价指标,优选胃肠宁胶囊的最佳提取工艺,然后筛选不同辅料,优选出最佳辅料,根据研究得出的最佳制备工艺制得胃肠宁胶囊。结果 实验得最优的提取工艺为处方加10倍量水,煎煮3次,每次1h,醇沉浓度为60%,药液浓缩至相对密度约为1.40(
2、60) 的清膏,加入1.5倍量的辅料(清膏:淀粉=1:1.5),混匀,制成软材,过2号筛制得胶囊内容物,烘干,整粒,用半自动胶囊填充板装填胶囊,即得胃肠宁胶囊。结论 本实验优选出的制备工艺稳定可靠,简单易行。关键词:胃肠宁胶囊;制备工艺;东莨菪内酯Study on the Preparation Technology of Weichangning CapsulesAbstract: Objective To establish HPLC method of scopoletin in weichangning extract, through L9(34) orthogonal test t
