摘要: 为了研究淡竹叶中黄酮类化合物提取方法。本文采用超声波-醇提-酯萃法,研究了提取的各种影响因素,通过正交试验设计,寻找最佳提取条件。试验结果表明,以60%乙醇为溶剂,固液比为1:30,经20kHz超声波提取30min,再经70℃水浴回流3h为最佳,在最佳实验条件下得到2.27%的收率。在试验影响因素中,影响程度从大到小依次为溶剂>回流温度>超声时间>超声强度>回流时间>溶剂浓度>固液比。

Abstract: To study the way of the flavonoid compounds extracted. The ultrasound-grade to-esters-crafts act was used, the various factors influencing extraction through orthogonal tests designed to find the best conditions was studied. The experimentalresults show that recovery was best in 60% ethanol as solvents, solid/liquid for 1:30, after 20kHz ultrasound extraction 30min via 70℃ water bath for returning 3h best in the best experimental conditions to be 2.27% in the rate. The experimental factors, the impact will activate by solvents, returning temperature, ultrasonic time, ultrasonic intensity, return time, solvent concentration, solid/liquid in order draw.
