摘要:以通常废弃的板栗苞为原料,经过提取得到板栗苞单宁提取物,并对提取物的纯化进行了研究。分别研究了吸附剂的选择、柱前液质量浓度、洗脱剂、蒸馏水的pH值、流速等单因素对单宁得率的影响,并通过正交试验得出了纯化的最佳工艺条件,即:选用大孔树脂D301为吸附剂,丙酮为洗脱液,柱前液质量分数为9%,蒸馏水pH值为7,过柱流速为0.4 L/h。最后,通过稳定性实验对所得工艺条件进行了验证,按此工艺条件纯化后的板栗苞单宁得率在82%以上,单宁质量分数在62%以上。
Purification of chestnut shell tannin from generally abandoned chestnut shell was studied.The effect of adsorbent,pre-column concentration,eluent,pH value of distilled water and flow rate on tannin yield was tested respectively.According to single factor and orthogonal experiment results,the optium experimental conditions were as follows: macroporous resin D301 as adsorbent,acetone as eluent,pre-column concentration 9%,pH value 7.0 of distilled water,flow rate 0.4 L/h.Finally,the best process condition was verified by stability test.Under these conditions,the yield of chestnut shell tannin was up to 82%,and tannin mass fraction was higher than 62%.
