This paper describes the preparation, characterization and use of a derivative of chitosan as a chromatographic sorbent. Chitosan modified with benzenic ring (CH-Bz) was used to separate two flavonoids, swertisin and 2"-O-rhamnosylswertisin, from ethyl acetate fraction of Aleurites moluccana. The results showed that CH-Bz can be used as a sorbent for the separation of flavonoid compounds. The studies showed that CH-Bz in column chromatography produces goods results, separation of the flavonoid compounds.
本文描述了一种壳聚糖衍生物作为色谱吸附剂的制备、表征及应用。用苯环修饰的壳聚糖（CH-Bz）从油桐乙酸乙酯萃取物中分离两种黄酮类化合物，即獐牙菜苷和2″-O-鼠李糖基獐牙菜苷。结果表明，CH-Bz可作为分离黄酮类化合物的吸附剂。研究表明，CH-Bz用于柱色谱法分离黄酮类化合物效果良好。
