本文采用气相色谱和气-质联用对猪苓滤液多糖的单糖组分和摩尔比进行研究。结果表明,猪苓滤液多糖由D-甘露糖、D-半乳糖、D-葡萄糖组成,其摩尔比为man∶gal∶glu=20∶4∶1。
In this paper, gas chromatography and gas-mass spectrometry were used to study the monosaccharide composition and molar ratio of Polysaccharides from Polyporus umbellatus. The results showed that the Polyporus umbellatus polysaccharide consists of D-mannose, D-galactose, and D-glucose in a molar ratio of man:gal:glu=20:4:1.
