超声波辅助法提取花生壳中木犀草素

Ultrasonic Assisted Extraction of Luteolin from Peanut Hull

采用超声波辅助法从花生壳中提取黄酮类物质——木犀草素,确定最佳工艺条件,并用紫外分光广度法测定其含量。最佳提取工艺参数为:提取溶剂为70%乙醇,料液比为1:10,提取时间为45分钟,分三次提取。该提取工艺具有省时、高效、节能等优点。

The flavonids-luteolin was extracted from peanut hulls with ultrasonic assisted. The optimum processing conditions were given. The spectrophotometry was used to check the luteolin. The optimum processing conditions were as follows：the solvent was 70% ethanol solution, the mass ratio of solid and solvent was 1： 10, the peanut hulls were extracted 15min for three times. The advantages of this methcd are high extraction efficiency,less time and energy saving.
