中文摘要:
      以桑葚果渣为原料,生物可降解低共熔溶剂(DESs)为溶剂,经DESs提取与大孔树脂分离两步,回收了果渣中花色苷。采用提取实验测试了不同类型DESs与提取方法对花色苷提取效率的影响,通过不同型号大孔树脂作为吸附载体对花色苷进行回收,脱除DESs,并对花色苷进行回收。采用HPLC、HPLC-MS对花色苷进行定量与定性。结果表明DESs中草酸-氯化胆碱是提取花色苷的最佳提取溶剂,提取率达97.49%;而在脱除DESs溶剂时,大孔树脂X-5是最佳吸附载体,回收率为92.76%。
英文摘要:
      Anthocyanins wasrecovered by two-step method using DESs to extract, macroporous resin to separate, and mulberry pomace as raw materials. The effect of different types of DESs and extraction methods on the extraction efficiency of anthocyanins was tested by extraction experiments. The anthocyanins were recovered, DESs was removed, and anthocyanins were recovered by using macroporous resin of different types as adsorption carrier. HPLC and HPLC-MS were used to quantify and characterize anthocyanins. As a result, oxalic acid-choline chloride stood out as the best DES for extraction, with an excellent yield efficiency of 97.49%, and macroporous resin X-5 was the best absorbent for the desolvation of NADESs, with a high recovery of 92.76%.
