Two water-soluble polysaccharides, BSP-1 and BSP-2, were extracted and purified from the tuber of Bletilla striata. The mol. weights of BSP-1 and BSP-2 were 83.54 kDa and 12.60 kDa, resp. The composition and proportion of BSP-1 and BSP-2 were mannose and glucose in molar ratios of 4.0:1.0 and 3.0:1.0 resp. The two polysaccharides had a linear backbone, consisting mainly of repeating β-1,4-linked D-mannosyl residues and β-1,4-linked D-glucosyl residues. BSP-1 exhibited immunomodulatory effects by increasing the thymus and spleen indexes of immunocompromised model mice.
International Journal of Biological Macromolecules published new progress about Bletilla striata. 3458-28-4 belongs to class alcohols-buliding-blocks, and the molecular formula is C6H12O6, Safety of (2S,3S,4R,5R)-2,3,4,5,6-Pentahydroxyhexanal.
