胭脂树低聚糖的结构分析
Structure Analysis of an Oligosaccharide Isolated from Bixo orellana by NMR Spectroscopy
【摘要】 从胭脂树(Bixo orellana)种子中分离得到了一种胭脂树低聚糖:α-D-半乳糖-(1→3)--αD-半乳糖-(1→6)-α-D-葡萄糖-(1→2)-β-D-果糖(BO-1).通过1D NMR和2D NMR实验技术对其1H NMR和13C NMR谱信号进行了全归属.
【Abstract】 An oligosaccharide,α-D-Gal-(1→3)-α-D-Gal-(1→6)-α-D-Glc-(1→2)-β-D-Fru(BO-1),was isolated from the seed of Bixo orellana.The 13C and 1H NMR chemical shifts of the compound were assigned by 1D and 2D NMR techniques,including COSY、HMQC and HMBC.
