beta-glucan prepared from mushrooms is used in both modern medicine and traditional oriental therapies because of its potent immunomodulatory properties. The effects of beta-glucan depend on its structure and origin. Therefore, elucidating the structure and source of beta-glucan is crucial for its use in food therapy and medicine. In this study, we performed NMR analysis of beta-glucan preparations from various mushrooms in order to determine their structure and source. Our results show that NMR spectroscopy can be used to determine the type of mushrooms from which a beta-glucan is derived on the basis of the structure of the beta-glucan. We believe that this method will help promote the use of beta-glucan in clinical settings and as a health food additive.
