摘要
采用热浸提法提取山药(Dioscorea batatas)中的黄酮,在单因素试验的基础上设计正交试验探讨乙醇体积分数、浸提时间、浸提温度和料液比对黄酮提取率的影响。结果表明,优化后的试验条件为体积分数70%的乙醇作为提取剂,料液比1∶20(m:V,g/mL),在50℃提取120 min。
The flavonoids in Chinese yam（Dioscorea batatas） were extracted by hot lixiviation.L9（34） orthogonal design was applied based on single factor tests to study the effects of fraction of ethanol volume,extraction time,liquid to solid ratio and extraction temperature on the yield of flavonoids.Results showed that the optimum conditions for extracting flavonoids were,volume fraction of ethanol,70%;solid to liquid ratio 1∶20（m：V,g/mL）;extraction time,120 min;and extraction temperature,60 ℃.
