| Abstract: | Two different glucans (PS-I and PS-II) were isolated from the alkaline extract of the fruiting bodies of an edible mushroom, Pleurotus florida blue variant and the PS-I showed macrophage, splenocyte and thymocyte activations. On the basis of sugar analysis, methylation analysis, periodate oxidation, and NMR studies ((1)H, (13)C, DEPT-135, DQF-COSY, TOCSY, NOESY, ROESY, HMQC and HMBC), the structure of the repeating unit of these polysaccharides were established. |
