以戊二醛交联的胶原纤维为吸附剂,研究其对芦丁和槲皮素的吸附分离特性。结果表明,在乙醇中,胶原纤维吸附剂对芦丁和槲皮素的吸附以氢键作用为主;在水中,吸附作用以疏水键为主。采用90%乙醇水溶液和70%乙醇水溶液进行分步洗脱,芦丁和槲皮素能够得到分离,回收率分别为96.70%和101.47%。胶原纤维吸附剂具有良好的重复使用特性,在5次重复分离实验中,其分离性能无明显降低。因此,戊二醛交联胶原纤维吸附剂可以用于芦丁和槲皮素混合物的分离。
以戊二醛交聯的膠原纖維為吸附劑,研究其對蘆丁和槲皮素的吸附分離特性。結果錶明,在乙醇中,膠原纖維吸附劑對蘆丁和槲皮素的吸附以氫鍵作用為主;在水中,吸附作用以疏水鍵為主。採用90%乙醇水溶液和70%乙醇水溶液進行分步洗脫,蘆丁和槲皮素能夠得到分離,迴收率分彆為96.70%和101.47%。膠原纖維吸附劑具有良好的重複使用特性,在5次重複分離實驗中,其分離性能無明顯降低。因此,戊二醛交聯膠原纖維吸附劑可以用于蘆丁和槲皮素混閤物的分離。

Collagen fiber cross-linked by glutaraldehyde was used as adsorbent for separation of rutin and quercetin.The results showed that rutin and quercetin were mainly absorbed by the adsorbent through hydrogen bonding in pure ethanol,while through hydrophobic interaction in water.The rutin-quercetin mixture could be separated on the column of collagen fiber adsorbent by stepwise elution of 90 % ethanol and 70 % ethanol,and their recovery was 96.70 % and 101.47 %,respectively.In addition,the separation capability of collagen fiber adsorbent was not obviously reduced after 5 times of repeated applications.Therefore,the collagen fiber adsorbent can be used for separation of rutin and quercetin mixture.
