title: GC-MS, FT-IR analysis of black fungus polysaccharides and its inhibition against skin aging in mice.
abstract: The monosaccharide compositions, molecular weights, structure were investigated for the black fungus polysaccharides. Analysis of sugar components by gas chromatograph-mass spectrometer (GC-MS) showed that component ratios of neutral sugars in the polysaccharides were Glc:Man=82.97:12.93. Fourier transform infrared (FT-IR) analysis showed that the band at about 1649cm(-1) can indicate the presence of CO groups or CC groups vibration in structures. Pharmacological experiment showed that black fungus polysaccharides administration could significantly reduce malondialchehyche (MDA), lipofuscin (LF) contents and enhance superoxide dismutase (SOD) activities in skin. This indicated that black fungus polysaccharides may slow down skin aging.
