Abstract

Six saponins were isolated from the leaves of Melanthera scandens. Their structures were elucidated by 2D NMR techniques, including ROESY. They are 3-O-beta-D-glucuronopyranosyl- oleanolic acid, 3-O-[beta-D-xylopyranosyl(1-->4)beta-D-glucuronopyranosyl]- oleanolic acid, 3-O-([beta-D-glucopyranosyl(1-->2)] [beta-D-xylopyranosyl- (1-->4)]beta-D-glucuronopyranosyl)-oleanolic acid, and the corresponding 28-O-beta-D-glucosides.

摘要

从攀缘金纽扣的叶子中分离出了六种皂苷。通过包括ROESY在内的二维核磁共振技术阐明了它们的结构。它们分别是3-O-β-D-葡糖醛酸吡喃糖基齐墩果酸、3-O-[β-D-木糖吡喃糖基(1→4)β-D-葡糖醛酸吡喃糖基]齐墩果酸、3-O-([β-D-吡喃葡萄糖基(1→2)][β-D-木糖吡喃糖基-(1→4)]β-D-葡糖醛酸吡喃糖基)齐墩果酸，以及相应的28-O-β-D-葡萄糖苷。
