从葛根废弃料中快速提取葛根异黄酮的方法
摘要：
本发明涉及从葛根废弃料中快速提取葛根异黄酮的方法。具体操作步骤是：（1）将葛根废弃料粉碎，采用液态CO2膨化；（2）采用超声波对膨化料二次提取，合并二次的提取液，经过滤、离心得到清液；（3）对清液进行减压浓缩，进行冷冻干燥，得到粗品葛根异黄酮，其中葛根异黄酮的纯度≥11%，异黄酮提取率≥92%。本发明提取时间短，溶剂用量少，提取成本较低。
摘要（英）：

The invention relates to a method for rapidly extracting pueraria isoflavones from pueraria waste. The method specifically comprises the following steps of: (1) crushing the pueraria waste, puffing by adopting liquid state CO2; (2) secondarily extracting the puffed pueraria waste by adopting supersonic waves, mixing extracting solutions of two times, and obtaining clear liquid through filtering and centrifuging; and (3) carrying out vacuum concentration on the clear liquid, and freeze-drying to obtain a crude product of pueraria isoflavones, wherein the purity of the pueraria isoflavones is not less than 11percent, and the extraction ratio of isoflavone is not less than 92 percent. The method has advantages of short extracting time, little solvent consumption, and low extracting cost.
