油橄榄叶片中黄酮的提取工艺探究

通过优选确立2年生油橄榄弗奥叶片中黄酮的最佳振荡加热提取条件，以其总黄酮含量为指标，用正交分析法对叶片细度、提取时间、提取剂乙醇的浓度3个因素对试验结果的显著性进行分析，优选研究得到叶片细度对该方法提取黄酮影响不显著，而提取时间和乙醇浓度都较显著最佳提取时间为6h，提取剂乙醇的最佳浓度为75％。结果表明油橄榄叶片中黄酮的最佳振荡加热提取工艺为A1B1C1，即叶片细度为100目、提取时间为6h、乙醇浓度为75％。

Flavone Extraction Technology from Leaf of Olea europaea

Through optimal selection,this experiment establishes optimum vibration heating extraction condition of flavanone in Chinese Olea europaea Frantoio two year old plantation leaf blade,take its total flavanone content as the markers,Analyze the significance of the three factors,the extranction time,extractant,ethyl alcohol,density and the leaf blade degree of fineness,on the test result by the orthogonal analysis.From the optimal selection scheme,we know that the effect of the leaf blade gegree of fineness on...
