%X Polysaccharide β-glucans were extracted from the medicinal mushroom Phellinus linteus (Hymenochaetaceae, Aphyllophoromycetideae) and subjected to sulfation. Chemical modification of the β-glucan was confirmed by structural analysis, and its biological properties were compared with those of native β-glucan. The results of Fourier transform infrared spectroscopy and elemental analysis indicated that successive preparation of the sulfated derivative yielded a degree of substitution of 0.47. Nitric oxide production measured by the bronchoalveolar lavage (BAL) experiments increased 1.5-fold after sulfation. In addition, the introduction of sulfate groups into the β-glucan chains improved in vitro growth inhibitory activity against SNU-C2A cells. Therefore, sulfated β-glucan extracted from Ph. Linteus may be beneficial for immune support due to its incorporation of functional groups into its polymer structure.
