摘要:为了研究其总黄***的提取工艺,以苦荞麦不同器官为原料,采用高压提取、超声波萃取、高压提
取+超声波萃取混合萃取苦荞麦黄***含量。结果表明:高压 15 min,测定黄***含量:叶片 %、茎秆
%、根系 %;超声波萃取为 60 min,测定黄***含量:叶片 %、茎秆 %、根系 %;实施高
压+ 超声波混合提取,以高压 10 min + 超声波 30 min,提取的黄***含量最高:其叶片黄***含量的平均值
为 %,比相同条件的高压提取(%)增加 %,比相同条件的超声波萃取(%)增加 %。高
压10 min+超声波30 min的回收率最高,%。

This text studied on the methods of extracting flavonoids of ans on the bitter buckwheat
Abstract:
as raw materials. The method was the high pressure extraction and the Ultrasonic extraction and the mix high
pressure and the Ultrasonic extraction. The results showed that, in high pressure extraction 15 min, the content
of flavonoids in the leaf was % and that of stem was %, and that of root was %. In the Ultrasonic
extraction 60 min, the content of flavonoids in the leaf was % and
