Abstract
Fructans are generally divided into two different types: β-D-fructofuranosyl-(2→1)-linked inulin and β-D-fructofuranosyl-(2→6)-linked levan. Previously, Radix Codonopsis was found to be rich in inulin type of fructans with low molecular weight (<5000 Da). In this study, a novel macromolecular fructan with a molecular weight of 1.70 × 103 KD was isolated from Radix Codonopsis, and its homogeneity was shown to be a single peak by high performance gel permeation chromatography (HPGPC), and its structure was confirmed to contain a new type of linkage, α-D-fructofuranosyl-(2→3)-β-D-fructofuranosyl linkage, by 1D- and 2D-nuclear magnetic resonance (NMR).
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
