采用加热回流方法提取地榆中的有效成分,分别以地榆中黄酮、皂苷和鞣质提取率为指标,考察同时提取这三种成分的影响因素（乙醇浓度、溶剂倍量、提取时间、提取温度和粒径）和最佳提取条件。结果表明,以60%乙醇为溶剂,药材粉碎粒径为20～40目,溶剂倍量为60,80℃下浸提1.5h的条件下提取效果最佳,在此条件下能够最好的兼顾三种有效成分的综合提取效率。
採用加熱迴流方法提取地榆中的有效成分,分彆以地榆中黃酮、皂苷和鞣質提取率為指標,攷察同時提取這三種成分的影響因素（乙醇濃度、溶劑倍量、提取時間、提取溫度和粒徑）和最佳提取條件。結果錶明,以60%乙醇為溶劑,藥材粉碎粒徑為20～40目,溶劑倍量為60,80℃下浸提1.5h的條件下提取效果最佳,在此條件下能夠最好的兼顧三種有效成分的綜閤提取效率。

The optimum conditions of extracting active principles from Sanguisorba officinalis L.with refluxing extraction methods were studied in this article.The effects of the amount of the solvent,concentration of alcohol,extraqction temperature,particle size of drug and extraction time were explored.The results of the optimum extracting conditions showed that the 60% ethanol was the best solvent in the experiment,the particle size was 20-40 meshs,the solid-liquid ratio was 1∶60,and extracted 1.5 h at 80℃.The optimized process was stable and workable.
