植物多糖结构解析方法研究进展

Research Progress in Analytical Methods for Structures of Phytogenic Polysaccharides

  • 摘要: 植物多糖是一类广泛存在于植物细胞中的天然大分子,具有抗肿瘤、抗氧化、免疫调节等多种生物活性,而多糖的结构是影响其生物活性的关键因素。由于多糖分子量大,结构复杂,使得多糖的深入研究受到限制。本文介绍了植物多糖初级结构解析方法如气相色谱法、液相色谱法、红外光谱法、核磁共振波谱法、质谱法等,以及高级结构解析方法如原子力显微镜法、X射线衍射法、圆二色谱法等,并对植物多糖多维指纹图谱和分子模型的构建进行归纳总结,为研究多糖结构提供了新的思路,为多糖的开发和利用奠定了基础。

     

    Abstract: Phytogenic polysaccharide, a kind of natural macromolecule, is wide spread occurrence in phytogenic cells and has many kinds of biological activities, such as anti-tumor, anti-oxidation, immunomodulation, and etc. The structure of polysaccharide is a key factor affecting its biological activity. Due to the large molecular weight and complex structure of polysaccharide, the in-depth study of polysaccharide is limited. Therefore, this paper introduces the research methods of the primary structure, such as gas chromatography, liquid chromatography, infrared spectroscopy, nuclear magnetic resonance spectroscopy and mass spectrometry, as well as advanced structural analysis methods such as atomic force microscopy, X ray diffraction and circular dichrois, and summarizes the construction of multidimensional fingerprint and molecular model of phytogenic polysaccharides, which provides a new idea for the study of polysaccharide structure and lays a foundation for the development and utilization of polysaccharides.
