柑橘皮中黄酮提取工艺研究

Study on the extraction technology of flavonoids from orange feel

柑橘在加工生产橘汁和新鲜使用时,约产生30%50%的皮渣,这些皮渣中有许多有用的成分,黄酮是其主要化学成分之一。本试验采用有机溶剂浸泡法对柑橘皮黄酮的提取工艺进行研究,得出了柑橘皮黄酮的最佳提取工艺条件:乙醇浓度60%,料液比1:50,提取时间28h,柑橘子皮黄酮的提取率为1.843%。

The extracting technology of orange flavonoids was studied and the results showed that the optimum extraction conditions were： ethanol concertration 60%, proportion of materials and solvent 1 ： 50 （ W/V）, extracting time 28h and the extractingt rate of total orange flavonoids was 1. 843%.
