Abstract
目的:优选痤疮消凝胶的提取工艺,为该制剂的临床应用提供参考.方法:以大黄游离总蒽醌、栀子苷、咖啡酸含量的综合评分为指标,采用均匀设计法考察乙醇体积分数、乙醇用量、提取时间和提取次数对提取工艺的影响.采用HPLC测定大黄游离总蒽醌、栀子苷、咖啡酸含量,流动相分别为甲醇-0.1%磷酸溶液(85: 15),甲醇-水(23:77),乙腈-0.1%磷酸溶液(10: 90),检测波长依次为254,238,323 nm.结果:最佳提取工艺参数为加12倍量80%乙醇提取3次,每次1h.大黄游离总蒽醌、栀子苷、咖啡酸质量浓度分别为1 260.33,1 597.56,32.19 mg·L-1.结论:优选的痤疮消凝胶提取工艺合理可行、重复性好,为该制剂生产工艺参数的确定提供实验依据.
