摘要： 用正交试验法对杜仲中的活性成分桃叶珊瑚苷的提取工艺进行了优选研究,采用正交表L16(45),以提取时间、提取温度、提取次数、提取液中有机溶剂乙醇含量以及料液比为因素,以桃叶珊瑚苷吸光度为指标进行试验。得到的最佳提取参数为:温度为70℃,时间0.5h,提取次数3次,提取溶剂为80%的乙醇,料液比为1:9。在此条件下,选取了提取桃叶珊瑚苷的最佳原材料,为杜仲新干皮。

Abstract: The optimum technology of extracting aucubin, the bioactive component in Eucommia ulmoides, was studied by orthogonal test. An orthogonal test table L16(45) was used with the factors of extracting time, temperature, times, ethanol concentration and the ratio of solid to liquid.The content of aucubin was determined by spectrophotometry.The optimum technology was:temperature 70℃, time 0.5 h, three times, 80% EtOH as extracting solvent, stock ratio 1:9.Under this condition, the best raw material of E.ulmoides for extracting aucubin was chosen, namely the freshly dried bark.

Key words: Eucommia ulmoides Oliver, aucubin, orthogonal test
