Two new gallic acid glycosides, potentillanosides G (1) and H (2), were newly isolated from the methanol extract of the tuberous roots of Potentilla anserina (Rosaceae), together with a known compound, ellagic acid 3-O-α-l-rhamnopyranoside (3). Their structures were elucidated on the basis of chemical and physicochemical evidence. Among the constituents, potentillanoside H (2, IC50 = 99.5 μM) was found to show hepatoprotective activity.
从荠菜(蔷薇科)块根的甲醇提取物中分离出两种新的没食子酸苷,即荠菜苷 G (1) 和 H (2),以及一种已知的化合物鞣花酸 3-O-α-L-吡喃鼠李糖苷 (3)。根据化学和物理化学证据阐明了它们的结构。在成分中,荠菜苷 H (2,IC50 = 99.5 μM) 具有保肝活性。
