Abstract: The origin and distribution of oligosaccharides of TCM are extensive, and its special biological activity and chemical properties have great potential in health preserving and disease prevention and treatment. The researches about its components are increasing, and its research and application are expanded. Oligosaccharides of TCM can be obtained by natural extraction, degradation and artificial synthesis. Among them, the natural extraction method is the most suitable for chromatography. The oligosaccharides of TCM have different groups and connections, and the structure is complex, with different chemical reactions in the process. This article reviewed the research overview of oligosaccharides of TCM from the aspects of separation, biological activity and chemical reactions in the process.

息类物质。中药寡糖特殊生物活性和自身化学性质已引起了高度关注,尤其是在营养保健、疾病防治方面有巨大潜力,其发现和分离的相关研究极大推动了中药寡糖领域研究进展,并不断拓展其应用范围。兹从中药寡糖的分离、生物活性及炮制过程中化学反应等方面综述该领域研究概况。
1 分离
中藥寡糖类混合成分很难得到分离提取,其主要原因是寡糖本身包含了很多结构相似的化学成分,具有多种可能的异构体,基团分子之间的多种连接形式和分支方式也造成其结构的复杂性。……
