摘要
目的优选固本止咳膏的水煎煮提取工艺。方法用均匀设计的方法安排实验,以多糖含量及黄芪甲苷含量为考核指标,考察煎煮次数、煎煮时间及加水量对上述有效成分提取率的影响,优选合理的提取工艺。结果以水为溶剂,煎煮3次,每次煎煮2h,每次加水量为药材用量的9倍为最佳提取工艺。结论优选出的最佳工艺可提取出药材中大部分的有效成分,此工艺是科学的。
Objective To optimize the water extractive process of Guben Zhike Electuary. Methods To arrange experiments with uniform design for optimizing suitable extractive proces, with the content of polysaccharide and astragaloside IV as the detecting indexes, inspecting the extacting times, lasting time and additional water which would affect the extraction rate of the two effective components. Result The best process was that water as extraction solvent, extracted for three times with two hours each time, and the amount of water added up to nine times of herbs. Conclusion The best process could extract most of the effective components out of the herbs, which is scientific.
