朝鲜蓟叶中的酚性糖苷化合物(英文)

Phenolic Glucoside Gallates from the Leaves of Cynara scolymus(Compositae)

从朝鲜蓟(Cynara scolymus)叶中分离得到2个酚性糖苷化合物,其中一个是新化合物,通过波谱学方法确定其结构为2-甲氧基-4-(2,3-二羟基-丙酰基)-苯基-1-O-(6′-O-没食子酰基)-β-D-吡喃葡萄糖苷(1)。

A new phenolic glucoside gallate, named 2-methoxy-4 -（ 2, 3-dihydroxy-propionyl ）-phenyl-1-O-（6′-O-galloyl）-β-D-glueopyranoside （1）, together with a known phenolic glucoside gallate （2）, were isolated from the leaves of Cyruzra scolymus （Artichoke）. The structure of 1 was elucidated mainly by extensive spectral methods （MS, IR, 1D and 2D NMR techniques）.
