板蓝根木脂素苷A的平面结构研究

STUDIES ON THE PLANESTRUCTURE OF INDIGOTICOSIDE A

经过溶剂法和各种色谱方法从十字花科菘蓝属植物板蓝根 (IsatisindigoticaFort.)的抗病毒有效部位中分离得到 1个化合物 :板蓝根木脂素苷A(IndigoticosideA ;3 (4 O β D glu copyranosyl α hydroxy 3 methoxy benzyl) 4 (4 hydroxy 3 methoxy benzyl)tetrahydrofuran) .通过谱学分析 (1 HNMR、1 3CNMR和 2DNMR)对该新化合物的碳氢信号进行了确切归属 .

A novel compound named Indigoticoside A (3 (4 O β D glucopyranosyl α hydroxy 3 methoxy benzyl) 4 (4 hydroxy 3 methoxy benzyl) tetrahydrofuran) was seperated from the antiviral site of Isatis indigotica Fort. by solvent and chromatography. \{\}\+1H and 13 C signals of the novel compound were assigned by spectroscopic methods.
