摘要
本文选用了四种大孔吸附树脂对紫菜薹色素进行浓缩分离研究,其中NKA-Ⅱ树脂效果较好。试验结果表明,用0.3%柠檬酸-60%乙醇溶液作为洗脱液,经吸附-解吸循环,色素的回收率可达92.8%,同时可将提取液中的色素浓缩10倍以上。
The optimum concentrating conditions of Brassica campestris pigment by macroporous adsorption resin were studied.As a result,while macroporous adsorption resin NKA- Ⅱ with a solution containing 0.3% citric acid and 60% ethanol as eluent was selected,the concentration efficiency was very good.The recovery rate was up to 92.8% and pigment of the abstract liquid could be concentrated 10 times through The adsorption- elution cycle.
