刺苋总黄酮的超声提取工艺研究

摘要

The method of extracting total quantity of flavone from Amaranthus spinosus and the effect of concentration,time,temperature,ratio of material to liquid was discussed.Meanwhile,the optimized conditions for extraction were determined by orthogonal analysis.The best parameters were 40% ethanol as extractant,temperature 60℃,extraction time 2h,ratio of material to liquid 1：20.In this case,the rate of extraction could reach up to 2.83mg/g.%采用超声法对刺苋药用成分进行了提取研究,探讨了溶剂浓度、提取时间、温度、料液比等因素对提取的影响。并通过正交法对刺苋总黄酮的超声提取进行了优化,确定了超声提取的最佳工艺参数为：乙醇浓度40%,温度60℃,提取时间2h,料液比1：20。按此优化条件提取总黄酮量为2.83mg/g。
