Dataset of the infrared spectrometry, gas chromatography-mass spectrometry analysis and nuclear magnetic resonance spectroscopy of the polysaccharides from C. militaris

Abstract

The data presented in this article describe characteristics of the polysaccharides, designated as CM1 and CMS, isolated from the fruiting body of C. militaris. Fourier transform infrared spectrometry analysis was used to identify the basic characteristics of the polysaccharides and the completeness of methylation. Gas chromatography-tandem mass spectrometry and nuclear magnetic resonance spectroscopy were carried out to reveal the glycosidic linkages of CM1 and CMS. Further interpretation and discussion could be found at our research article entitled “Structural characterisation and cholesterol efflux improving capacity of the novel polysaccharides from Cordyceps militaris” (Hu et al., 2019; https://doi.org/10.1016/j.ijbiomac.2019.03.078) [1].
