摘　　要：根据黄连中主要有效成分生物碱易溶于热水的性质，采用正交设计筛选出黄连水提取的最佳工艺条件，并分别以回流提取、连续回流提取方式，比较水和50％乙醇作溶剂的提取效果，结果显示二者基本相同。表明黄连水提取是完全可行的。Based upon the fact that the main active principle alkaloids in root of Coptis chinensis are easily soluble in hot water,optimum water extraction conditions were explored by orthogonal tests in comparison with the conventional 50% ethanol extraction process. Results proved that the two methods gave very similar results,suggesting that water could be used to extract root of C. chinensis.
