为研究烟草果胶的精细结构和掌握果胶提取的关键因素,采用交叉极化/魔角旋转固态核磁光谱技术(CP/MAS13C NMR)考察了酸提取条件(p H、温度和提取时间)对烟草果胶产率、纯度(质量分数)及结构的影响。结果表明:1在p H 1.5和85℃条件下提取...为研究烟草果胶的精细结构和掌握果胶提取的关键因素,采用交叉极化/魔角旋转固态核磁光谱技术(CP/MAS13C NMR)考察了酸提取条件(p H、温度和提取时间)对烟草果胶产率、纯度(质量分数)及结构的影响。结果表明:1在p H 1.5和85℃条件下提取1.5 h时,烟草果胶得率最高,为10.87%,但在p H 2.0和95℃条件下提取1.5 h时,聚半乳糖醛酸(PGA)的纯度最高,为78.4%。2提取条件对烟草果胶的结构也有一定的影响,p H=1.5~2.5时,果胶的甲酯度(DM)和乙酰度(DA)均随p H升高而增大,随温度升高而降低,随提取时间延长而显著下降。展开更多

We performthe diagonalization of this model in the presence ofmagnetic field. From the full energy spectrum, the central charge and the scaling dimensions are given at the criticalpoint. The results show evidently that the quantum Ising criticality exists in such a system.展开更多

We performthe diagonalization of this model in the presence ofmagnetic field. From the full energy spectrum, the central charge and the scaling dimensions are given at the criticalpoint. The results show evidently that the quantum Ising criticality exists in such a system.
