摘要
目的：研究肠胃清颗粒最佳水煎提取工艺。方法：选择L_9（3~4）进行正交试验,以黄芪甲苷含量、浸膏得率和多糖含量作为检测指标,考察浸泡时间、煎煮时间、用水量等因素对水提效果的影响,优选肠胃清颗粒的最佳提取工艺。结果：肠胃清颗粒最佳提取工艺为加水浸泡0.5h,水煎3次,每次煎煮1.5h,每次用水量为药材的10倍量。结论：该工艺对有效成分的提取率高,且稳定可行。
Objective：To study the optimizing water extracting technology of Changweiqing Granule.Methods：The best extracting technology of Changweiqing Granule was optimized by selecting L_9（3~4）orthogonal test,making astragaloside content,extract yield and the polysaccharide content as the detection index,investigating the effect of soaking time,boiling time,water consumption and other factors on water extraction.Results：The best extracting technology of Changweiqing Granule was defined as follows：soaking 0.5h,water extracting for 3 times and 1.5h each time,10 folds of water.Conclusion：The technology has a high extraction rate of active ingredients and is stable and feasible.
