摘要: 为研究奶子藤(Bousigonia mekongensis)根的化学成分及生物活性。采用正相硅胶、RP-18、制备液相等色谱技术,对奶子藤根中的化学成分进行了分离纯化,共分离得到9个化合物,通过NMR、MS等波谱方法将其结构鉴定为:quebrachamine (1)、(-)-isoeburnamine (2)、rhazinilam (3)、tetrahydroalstonine (4)、leuconodine D (5)、leucophyllidine (6)、(-)-O-ethyleburnamine (7)、(-)-ebumamenine (8)、eburenine(9)。化合物13~7首次从该属植物中分离得到,化合物2为首次从该植物中分离得到。所有化合物测试了拮抗高糖所致的足细胞损伤和抑制淀粉样蛋白-β(Aβ)两种生物活性,结果显示化合物6具有一定的Aβ抑制活性(IC50 = 26.1 μM),其余化合物均未显示出生物活性。

Abstract: In order to investigate the chemical constituents and biological activities of Bousigonia mekongensis,nine compounds were isolated from the roots of B. mekongensis by repeated column chromatography over silica gel,RP-18 and preparative-HPLC.On the basis of NMR and MS spectroscopic analysis,their structures were identified as quebrachamine (1),(-)-isoeburnamine (2),rhazinilam (3),tetrahydroalstonine (4),leuconodine D (5),leucophyllidine (6),(-)-O-ethyleburnamine (7),(-)-ebumamenine (8),eburenine (9),respectively.Compound 1 and 3-7 were obtained from this genus for the first time,and compound 2 was isolated from this plant for the first time.All compounds were evaluated the activities of preventing high glucose-induced podocyte injury and inhibiting of amyloid-β.Compound 6 exhibited moderate Aβ inhibitory activity (IC50= 26.1 μM),other compounds showed no activity.
