摘　　要：为定向设计并制备改性纤维素球用于天然产物香草酸的分离,通过制备交联羧甲基纤维素负载铈(CMC-Ce)球,并接枝三乙烯四胺,合成胺基改性CMC-Ce球。通过傅里叶变换红外吸收光谱(FT-IR)、扫描电镜(SEM)和X-射线衍射(XRD)对材料进行表征。采用高效液相色谱法(HPLC)进行化学成分的定性和定量检测分析,以研究吸附材料对蒲公英中活性成分的吸附分离效果。最终成功合成胺基改性CMC-Ce球,利用该球可以分离出蒲公英中的香草酸(吸附率45.70%,解吸率为77.57%)。胺基改性CMC-Ce球成功从蒲公英中分离出香草酸,为植物中香草酸的高通量分离提供了新的思路和方法。Modified cellulose spheres were designed and prepared for separation of natural product vanillic acid.Cross linked carboxymethyl cellulose spheres supported Cerium(CMC-Ce)were prepared,which grafted triethylenetetramine to synthesize amine-modified CMC-Ce spheres.The materials were characterized by Fourier transform infrared spectroscopy(FT-IR),scanning electron microscopy(SEM),and X-ray diffraction(XRD).High performance liquid chromatography(HPLC)was used for qualitative and quantitative detection of chemical components,for studying the adsorption and separation effect of the adsorption materials on active components in Taraxacum mongolicum.Amine-modified CMC-Ce spheres can be successfully synthesized.And the vanillic acid can be separated from T.mongolicum by the spheres with the adsorption capacity of 45.70%and desorption capacity of 77.57%.Vanillic acid can be successfully separated from T.mongolicum by amine-modified CMC-Ce spheres,which provides a new idea and method for high throughput separation of vanillic acid from plants.
