目的:优选渭良伤科贴膏的提取工艺。方法:以干膏量和提取液中栀子苷含量为指标,以水为提取溶媒,采用正交试验法,来考察提取次数、加水量、提取时间、药材粉碎度、浸泡时间对渭良伤科贴膏提取效果的影响。结果:最佳提取条件为:取药材饮片先加水浸泡2 h,然后提取2次,第一次提取1.5 h,加水量为13倍,第二次提取1 h,加水量为10倍。结论:该提取工艺稳定可行。
Objective: To optimize the extraction process of Wei-Liang wound plaster. Methods: Taking the amount of dry cream and the content of geniposide in the extract as an index, taking water as the extraction solvent, the orthogonal test was used to investigate the effects of extraction times, water addition, extraction time, The effect of sticking plaster extraction effect. Results: The best extraction conditions were as follows: the medicinal herbs were immersed in water for 2 h, then extracted twice, the first extraction was 1.5 h, the amount of water was 13 times, the second extraction was 1 h, the amount of water was 10 times. Conclusion: The extraction process is stable and feasible.
