伤科消肿止痛膏制备工艺以及有效成分含量测定
Journal of Wenzhou Medical University(2019)
Abstract
目的:优选伤科消肿止痛膏的制备工艺,测定指标成分的含量.方法:设计正交实验优选伤科消肿止痛膏醇提工艺.运用单因素考察法优选制备工艺.采用HPLC色谱法检测大黄素和虎杖苷的含量.结果:优选的醇提工艺为7倍量的70%乙醇提取3次,每次2?h.优选的制备工艺为明胶和阿拉伯胶的比例为1:4,使用3倍量伤科消肿止痛膏提取液,所得膏体黏度适中.测得大黄素的含量为4.14?μg·g-1,虎杖苷的含量为12.71?μg·g-1.结论:实验优选的工艺稳定可行,可用于伤科消肿止痛膏制备.选取的指标成分大黄素和虎杖苷含量测定结果稳定,可用于质量控制.
