【摘要】 本文以物理及化学方法研究了巴西蘑菇AgaricusblazeiMurill水溶性多糖AB-I、AB-II-b和AB-III-b的理化性质,结果表明,3种经纯化的多糖都不含糖醛酸而含蛋白质,蛋白质含量分别为AB-I:20.1%、AB-II-b:16.3%、AB-III-b:25.6%。它们的比旋度分别为AB-I:+44.33°、AB-II-b;+3.70°、AB-III-b:+5.04°。AB-I、AB-II-b的1.0%水溶液均具有良好的增稠性,其粘度具有很好的抗盐浓度、耐热和对广泛pH的稳定性能。更多还原

【Abstract】 Some physical and chemical properties of polysaccharides of Agaricus blazei were investigated in this paper. The results showed that three groups of purified polysaccharide were free from urinic acid. The protein content of the polysaccharides was AB-I 20.1%, AB-II-b 16.3% and AB-III-b 25.6%. The specific rotatory power of the polysaccharides was AB-I +44.33°, AB-II-b +3.70°, AB-III-b +5.04°. The viscosity of AB-I and AB-II-b was increased with the increase of solution concentration . The viscosity of 1% AB-I and AB-II-b was stable in different concentration of NaCl, pH value and temperature.更多还原
