摘要
以酸枣叶为材料,采用乙醇回流法提取酸枣叶中的三萜皂苷类物质,通过对料液比、浸提剂浓度、浸提时间、浸提温度等条件对三萜皂苷类物质提取效果的影响研究,经正交试验对各因素影响下的提取工艺进行了优化,确定了酸枣叶中三萜皂苷类物质的乙醇回流法提取的最优工艺为:料液比1:20,浸提剂浓度为75%,浸提时间120 min,浸提温度70℃,浸提率达到为6.62%。
Using ethanol reflux method to extract triterpenoid saponins from ziziphus jujube leaf, the studyresearched the effect of liquid ratio, leaching agent concentration, leaching time, leaching temperature onthe extraction of triterpenoid saponins, and then did the orthogonal experiment to determine the bestextract condition. It was liquid ratio 1：20, leaching agent concentration 75%, leaching time 120 min,leaching temperature 70℃, and the leaching rate 6.62%.
