目的优选咳喘灵凝胶膏剂合提的提取工艺。方法以药材粉碎度、乙醇用量、乙醇浓度和加热时间为可变因素,以芥子碱硫氰酸盐的含量与干浸膏得率为考察指标,采用L9(34)正交实验优选提取工艺。结果优选工艺为:以8倍量60%的乙醇提取粗粉药材提取3h。结论优选的工艺简便、合理,为进一步的研究奠定了良好的基础。 Objective To optimize cough Ling gel cream extraction process. Methods The degree of crude drug, the amount of ethanol, the concentration of ethanol and the heating time were used as variables. The content of sinapine thiocyanate and the yield of dry extract were taken as the indexes. The extraction process was optimized by L9 (34) orthogonal experiment. Results The preferred process was: extraction of crude meal with 8 times the amount of 60% ethanol extracted 3h. Conclusion The preferred process is simple and reasonable, which lays a good foundation for further research.
