本文用IR、~(13)C-NMR、~1H-NMR、MS、元素分析手段对田菁胶原粉和环氧丙烷反应的合成样品进行系统地结构研究,证明样品为羟丙基型半乳甘露聚糖类,其主结构与田菁胶原粉一致,并用~1H-NMR法测定了羟丙基田菁胶的醚化度(D.S).
In this paper, a systematic study of the synthesis of Sesbania powder and propylene oxide by IR, ~ (13) C-NMR, ~ 1H-NMR, MS and elemental analysis showed that the sample was hydroxypropyl-type The main structure of mannan polysaccharides was the same as that of Sesbania, and the degree of etherification (DS) of hydroxypropyl sanshines was determined by ~ 1H-NMR.
