| 摘 要： | 利用AB-8大孔树脂对紫薯花色苷的吸附和解吸性能进行了研究，得到其静态吸附率为80．2％，静态解吸率为99．4％。当紫薯花色苷质量浓度为8．8mg／L时，100mL提取液需AB-8树脂4．0g，静态吸附140min，可使吸附量达到最大；解吸液为盐酸酸化的乙醇溶液（φEthanol=60％）时，可使解吸量达到最大。通过色价、HPLC分析表明用选定的树脂纯化方法能提高紫薯花色苷的品质。

| Abstract: | The performance of absorption and desorption of macroporous resin AB-8 to anthocyanin of purple sweet potato was studied. The results showed that its static absorption and desorption rate were 80.2 % and 99.4%respectively. The absorption quantity reached maximum in the situation that 100 mL extract needed AB-8 4.0 g and 140 min of static absorption, when the mass concentration of anthocyanin was 8.8 mg/L. The desorption quantity reached maximum using hydrochloric ethanol （φEthanol= 60% ） as desorption solution. The result was obtained that the quality of anthocyanin of purple sweet potato was increased by analysis of color scale and high performance liquid chromatography. |
