摘　　要：以女贞子为原料,对还原糖提取的影响因素及工艺进行研究。采用甲醇提的方法,分析提取温度、料液比、回流次数对女贞子还原糖提取含量的影响,采用DNS比色法测女贞子中还原糖的含量。在单因素基础上进行正交试验设计,筛选出最佳提取工艺。在提取温度为90℃、料液比为1∶60(g/m L)、回流次数8次的条件下,女贞子还原糖的提取含量最高,可达到262.30μg/m L,此时还原糖的提取率为5.246%。The objects were to study the influence factors and extraction process which will influence the extraction process of reducing sugar from the Ligustrum lucidum Ait. With methanol as extraction solvent,the effects of extraction temperature,solid-liquid ration and reflux times on the extraction contents were considered.Then the contents of reducing sugar were measured by DNS colorimetry. The optimal extraction process was optimized with orthogonal experiments followed by single factor tests. The highest content of reducing sugar was obtained when the extraction temperature was 90 ℃,the solid-liquid ration was 1 ∶ 60（g/m L）,and the reflux times were eight. At the optimum conditions determined by experiments,the extraction content of reducing sugar from Ligustrum lucidum Ait met 262.30 μg/m L,and the extraction coeffient was over 5.246 %。
