摘要
采用正交试验法对沙枣中鞣质的提取工艺进行优化,以总鞣质含量为指标,用EDTA络合滴定法测定鞣质含量。结果表明,沙枣鞣质的最佳提取工艺为10倍量50%丙酮浸泡12h,回流提取3h,沙枣总鞣质提取率为3.19%。
To optimizing the best tannin extraction process of total tannin from Gansu Elaeagnus angustifolia by orthogonal design,the total tannin content as the assessment index was determined through EDTA complexing titration. The best conditions for the extraction process were as follows： 10 fold volumes of 50% acetone solution, soaking for 6 hours,circumfluence extracting for 3 hours. The extraction yield of the total tannin was up to 3.19%.
