[摘要]目的 研究三十烷醇滴丸的最佳制备工艺条件。方法 以PEG4000和PEG6000为辅料、液体石蜡和植物油为冷凝液制备三十烷醇滴丸。采用单因素考察法确定冷凝液配比、基质质量比,采用L9(34)正交试验法考察药液温度、冷凝液温度、滴距、滴速对制备工艺的影响,确定最佳工艺。结果 三十烷醇滴丸的最佳制备工艺条件为:PEG4000:PEG6000=1:4;药液:基质=1:10;滴距3 cm,温度80~85℃,滴速30滴/min,冷凝温度10~15℃。该工艺制备的滴丸外观圆整度良好,硬度较好,色泽均一。结论 本法筛选的三十烷醇滴丸制备工艺可行,符合2010版《中国药典》中滴丸剂的质量规定。

[Abstract]Objective To determine the optimum preparation process of 1-Triacontanol Dropping Pills.Methods 1-Triacontanol Dropping Pills were prepared by PEG 4000 and PEG 6000 as excipient,proportional fluid wax and vegetable oil were used as condensate.Single factor test was used to screen the mass ratio of matrix and condensate.The L9(34) orthogonal test was used to screen the drug-soup temperature,condensate temperature,dropping distance,dropping speed and to decide the best preparation process.Results m(PEG4000):m(PEG6000)=1:4,m(API):m(matrix)=1:10,the temperature of drug was 80~85℃,the dripping speed was 30 drops per minute,the condensate temperature was 10~15℃,the dropping distance was 3 cm were the optimum preparation technology of 1-Triacontanol Dropping Pills.The preparation of the Drop Pills had a good roundness,a good hardness and a uniform color.Conclusion This method is feasible for the preparation of 1-Triacontanol Drop Pills,which is in accordance with the quality of the Dropping Pills in Pharmacopoeia of the People′s Republic of China (2010 edition).

三十烷醇普遍存在于植物蠟质中,常以蜂蜡和米糠蜡为原料制取,对光、空气、碱稳定,在水中的溶解度<9×10-14g/L,几乎不溶于水,难溶于冷乙醇、甲醇、苯,可溶于正己烷、乙醚、氯仿、二氯甲烷及热苯、热乙醇中[1]。经抗癌药效试验筛选,对多种实体癌具有抑制作用[2-3]。本研究旨在制备出一种能增加三十烷醇溶出度和生物利用度的制剂——三十烷醇滴丸。
文献记载三十烷醇在农业上作为植物生长促进剂,对农作物、水果、蔬菜有促进发芽、提高结实率、使其干粒重和提高晒干率等优点[2]。在随后的实验中,首次发现三十烷醇对多种实体瘤,如肝癌、肠癌、肺癌等有不同程度的抑制作用。三十烷醇是本研究研制的具有自主知识产权的候选新药,药效稳定[3-4],其制备方法成熟,曾成功从土瓜狼毒中分离出三十烷醇[5],工业上主要通过米秕糠醇提——皂化——分馏步骤,最终获得大量高纯度三十烷醇,其制备方法稳定,可作为原料药大量生产[6]。由于其特殊的低脂溶性、低水溶性、低熔点等特点,要将其做成药用制剂并不容易。……
