摘要
目的:探索大孔树脂脱除冬凌草提取物中色素的可行工艺。方法:以冬凌草中叶绿素的含量为指标,采用静态吸附-解吸和动态吸附-解吸实验,对5种树脂的脱色效果、脱色条件、树脂再生方法进行比较和筛选。结果:确定HZ-803为脱色用树脂,乙酸乙酯作为洗脱剂。在吸附流速为3 BV.h-1,解吸流速为5 BV.h-1,脱色率可达90%,经过15次循环使用,脱色率仍在70%以上。结论:HZ-803大孔吸附树脂对冬凌草提取物中色素具有良好的吸附和解吸性能。
Objective：A feasibility process was studied to separate chlorophyll from the extract of Rabdosia rubescens by macroporous resins.Methods：5 types of macroporous resins were compared with the absorption and desorption properties as decolorants for the elimination of chlorophyll by effects and conditions of decolorization and regeneration of resins.Results：Macroporous resin HZ-803 was selected from 5 types of ones by comparing the absorption and desorption properties as a decolorant for the elimination of chlorophyll,ethyl acetate as for eluent.The optimization of process conditions was studied with absorption flow rate 3 BV·h-1;desorption flow rate 5 BV·h-1;decolorization ratio for once was 90%;after 15 circulations the decolorization ratio was still above 70%.Conclusion：Macroporous resin HZ-803 was selected for the superperformance of the absorption and desorption properties as a decolorant for the separatation of chlorophyll from Rabdosia rubescens.
