大孔树脂吸附分离柚皮加工废液中的总黄酮

工业化生产加工柚皮过程中，采用树脂法吸附分离酸提果胶后的超滤膜透过液得柚黄酮柚皮苷。通过考察直接醇提液和超滤膜透过液中柚皮苷在树脂上的吸附性能，确定最佳吸附分离工艺条件。结果表明，醇提液和膜透过液均可用大孔树脂纯化，高效液相色谱（HPLC）测定显示从醇提液和膜透过液中分离得到的总黄酮在主要成分上没有明显区别，大孔吸附树脂对膜透过液的循环使用次数≥6次，AB-8大孔树脂适合应用到工业生产中对膜透过液回收柚皮黄酮，实现柚皮加工综合利用。

Macroporous resin adsorption of the flavone from the effluent in pomelo peel processing

Naringin was recovered from the effluent from the industrial processing of pomelo peel using extraction by acid,permeation through a membrane,and chromatography with a macroporous resin.The adsorption characteristics on the resin of the solution permeated through the membrane were found by HPLC to be identical to those of a direct alcohol extract of the effluent.Permeation of the solution through the membrane,however,allowed the macroporous resin to be reused at least 6 times without loss of performance.Use of the resin in the treatment of the effluent is therefore viable in an industrial plant.
