摘要:
目的:研究鸦胆子油自乳化制剂,探求其最佳处方配比,进行剂型改进。方法:通过溶解度实验、正交筛选和伪三元相图的绘制,以乳化程度、未乳化油的体积和所得乳滴粒径的大小为指标,对鸦胆子油处方中的药物、油相、表面活性剂的用量比例进行筛选,寻找出最佳的搭配和处方配比。结果:在鸦胆子油的自乳化制剂处方中,当油相选用中链脂肪酸三酰甘油、非离子表面活性剂选用吐温-85时,可以获得较好的乳化效果,粒径为0.169 2 μm,且乳化制剂的质量、稳定性与重现性良好。结论:鸦胆子油自乳化的最佳处方比例为鸦胆子油中链脂肪酸三酰甘油吐温-85=114。

Abstract:
Objective:To search for the optimum formula for self-emulsifying preparation of Brucea javanica seed oil.Methods: Taking the emulsifying degree,quantity of non-emulsifying oil,and emulsion particle size as parameters,we screened for the optimum proportions of the oil,lipids, and non-ionic surfactant in the recipe formulation through solubility experiment,orthogonal screen and drawing pseudo-three-phase diagram.Results: For the formulation of Brucea javanica seed oil,better emulsifying effect could be obtained using medium chain length fatty acid triglyceride as the lipids and Tween-85 as the non-ionic surfactant,with the emulsion particle diameter being 0.169 2 μm.And the self-emulsifying preparation had satisfactory quality,stability, and reproducibility.Conclusion: The optimum formula for self-emulsification of Brucea javanica seed oil is:Brucea javanica seed oil∶medium chain triglycerides∶Tween-85 being 1∶1∶4.
