为优选厚朴七物汤水提取工艺，采用正交试验法设计水提取工艺，以出膏率、含浸出物百分量和厚朴酚与和厚朴酚，及含大黄总蒽醌量为测定指标，考察加水量，提取次数和回流时间三个因素参数，确定最佳提取工艺条件．结果表明，厚朴七物汤最佳提取工艺为回流提取3次，第一次加水10倍量提取1．5 h，第二次加水8倍量提取1．0 h，第三次加水6倍量提取0．5 h．厚朴七物汤的水提取工艺简便易行，效率高，稳定可行．%To study the optimal extraction process of Houpu Qiwu decoction , the orthogonal experiment was used .The optimal extraction process was determined with the rate of extrac-tion, the percentage composition of extractive and the content of magnolol , honokil and total anthraquinone in radix et rhizoma rhei as the index .Results indicated that the optimal ex-traction of Houpu Qiwu decoction was reflux extraction 3 times, the first time of 1.5 h with 10 times water;the second time of 1 h with 8 times water, and the third time of 0.5 h with 6 times water.The optimal extraction technology was easy , high efficiency and stable .
