摘要: 目的:从南海鸢乌贼墨汁中分离纯化多糖,并分析其多糖组分。方法:利用水提醇沉法得粗多糖,通过固相萃取层析法除色素对多糖进行纯化,纯化多糖依次经DEAE-52离子交换柱、Sephacryl HR-300凝胶柱分级纯化,按峰收集得单一组分,采用1-苯基-3-甲基-5-吡唑啉酮(1-phenyl-3-methyl-5-pyrazolone,PMP)衍生化方法,通过超高效液相色谱分析多糖组分。结果:粗多糖经DEAE-52离子交换柱、Sephacryl HR-300凝胶柱后收集得到3?个糖组分,分别为SIP1、SIP2、SIP3;通过PMP衍生化方法分析单糖组成,得:SIP1是由D-甘露糖、D-葡萄糖、D-半乳糖3?种单糖缩合而成;SIP2和SIP3分别是由D-甘露糖、鼠李糖、D-葡萄糖、D-半乳糖及L-(-)-岩藻糖5?种单糖按照不同比例缩合而成。

Abstract: Objective: To isolate and purify polysaccharides from the ink of Sthenoteuthis oualaniensis in the South China Sea, and to analyze the monosaccharide composition of the purified polysaccharides. Methods: Crude polysaccharides were isolated through water extraction followed by alcohol precipitation and passed through a solid phase extraction column to remove the pigment. The polysaccharides were fractionated and further purified into homogeneity by sequential chromatographies on DEAE-52 ion exchange and Sephacryl HR-300 columns. The monosaccharide composition was analyzed by ultra performance liquid chromatography (UPLC) after 1-phenyl-3-methyl-5-pyrazolone (PMP) derivatization. Results: Three purified polysaccharides designated as SIP1, SIP2, and SIP3 were obtained. SIP1 was composed of D-mannose, D-glucose, and D-galactose while SIP2 and SIP3 were composed of D-mannose, rat sugar, D-glucose, D-galactose and L-(-)-fucose in different ratios.
