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).
從朝鮮薊(Cynara scolymus)葉中分離得到2箇酚性糖苷化閤物,其中一箇是新化閤物,通過波譜學方法確定其結構為2-甲氧基-4-(2, 3-二羥基-丙酰基)-苯基-1-O-(6′-O-沒食子酰基)-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-glucopyranoside (1), together with a known phenolic glucoside gallate (2), were isolated from the leaves of Cynara scolymus (Artichoke). The structure of 1 was elucidated mainly by extensive spectral methods (MS, IR, 1D and 2D NMR techniques).
