摘要:
从日本矢车菊(Coriaria japonica A. GRAY)叶片中分离出了两种新的可水解单宁,分别命名为矢车菊素 A 和 B,以及 1, 2, 3-三-O-谷氨酰-β-D-葡萄糖、香叶木脂素、tellimagrandins I (1)和 II (2)、豚草素 A、D 和 E。根据光谱和化学证据,已经确定了芫茜素 A 的结构 3(2 的二聚体)和芫茜素 B 的结构 4(相关的单体)。
A dimericellagitanningemin A (1), has been isolated from Geum japonicum Thunb., and its structure, which contains α- and β-glucosecores, has been elucidated.
