摘要: 本文报道了通过计算碳苷α,β端基异构体糖环上相同碳原子在13C-NMR全去偶谱和NNE谱中峰强度或峰面积之比进行定量研究的方法.结果表明,如果碳苷化合物具有合适的溶解度,可以得到很准确的结果,相对误差小于1%.

Abstract: In this paper, the method for the quantitative study of C-glucopyranosides using 13C-NMR speotrum through me peak intensity on peak area of sugar carbons was reported. If C-glucopyranosides were readily soluble in the solvent, accurate result can be obtained and relative error will be less than 1%.
