摘  要:对鬼针草Bidens bipinnata中的化学成分进行研究,筛选具有抗肝纤维化活性单体。采用大孔树脂、硅胶、MCI树脂、Sephadex LH-20等方法进行分离纯化,得到15个化合物,并运用波谱技术测试,鉴定其结构为槲皮素(1),槲皮素-3-O-α-L-鼠李糖苷(2),紫云英苷(3),山柰酚-3-O-α-L-鼠李糖苷(4),5,3'-二羟基-3,6,4'-三甲氧基-7-O-β-D-吡喃葡萄糖苷黄酮(5),7,8,3',4'-四羟基二氢黄酮(6),(R/S)-异奥卡宁-7-O-β-D-葡萄糖苷(7),(R/S)-异奥卡宁-3'-甲氧基-7-O-β-D-葡萄糖苷(8),6,7,3',4'-四羟基橙酮(9),海生菊苷(10),6,7-二羟基香豆素(11),3-咖啡酸酰基-2-甲基-D-赤藓糖酸-1,4内酯(12),(7S,8R)苯并二氢呋喃新木脂素-4-O-β-D-葡萄糖苷(13),丁香酚-O-β-D-呋喃芹糖-(1″-6')-O-β-D-吡喃葡萄糖苷(14),(+)丁香脂素-4-O-β-D-吡喃葡萄糖苷(15)。其中化合物8,13~15为首次从本属植物中分离得到。在初步的活性筛选中化合物1,6有较强体外抑制肝星状细胞增殖的能力;化合物1,2,6,7有较强体外抑制腹腔巨噬细胞分泌炎症因子的能力。To investigate the chemical constituents of the whole plants of Bidens bipinnata,the separation and purification of constituents were performed by chromatography on macroporous resin,silica gel,MCI and Sephadex LH-20.Their structures were elucidated by spectroscopic data as quercetin(1),quercetin-3-O-α-L-rhamnoside(2),keampferol-3-O-β-D-glucopyranoside(3),keampferol-3-O-α-L-rhamnoside(4),3',5-dyhydroxy-3,6,4'-trimethoxyl-7-O-β-D-glucopyranoside flavonoid(5),7,8,3',4'-tetraflavanone(6),(2S)- and(2R)-isookanin-7-O-β-D- glucopyranoside(7a /7b),(2S)- and(2R)-3'-methoxy-isookanin-8-O-β-Dglucopyranoside(8a /8b),6,7,3',4'-tetrahydroxyaurone(9),maritimetin(10),esculetin(11),3-O-caffeoyl-2-methyl-d-erythrono-1,4-lactone(12),(7S,8R) balanophonin-4-O-β-D-glucopyranoside(13),eugenyl-O-β-apiofuranosyl-(1″-6')-O-β-glucopyranoside(14),and( +)-syringaresinol-4'-O-β-D-glucopyranoside(15).Compounds 8,13,14,and 15 were isolated from this genus for the first time.Compounds 1 and 6 were potent inhibitors against HSC-T6 cells in vitro and compounds 1,2,6,and 7 were capable of decreasing the inflammatory cytokine production of macrophage cells in vitro.
