中文摘要:
      为了研究金花茶花中的木脂素类化学成分,采用硅胶柱,Sephadex LH-20凝胶柱,C18反相色谱柱,半制备高压液相色谱等色谱方法对金花茶花的化学成分进行分离纯化,运用1H-NMR、13C-NMR、ESI-MS等多种波谱技术鉴定化合物的结构。共得到8个木脂素类化合物,分别鉴定为:桉脂素(1)、(+)-diasyringaresinol(2)、(+)-isoeucommin A(3)、Pinoresinol 4-O-glucoside(4)、7S, 8R, 8’R-(-)-lariciresinol-4’-O-D-glucopyranoside(5)、(+)-Isolariciresinol 9-O-β-D-glucopyranoside(6)、(+)-Isolariciresinol 9’-O-β-D-glucopyranoside(7)、3’, 4-O-dimethylcedrusin(8)。所有化合物均为首次从该植物中分离得到。
英文摘要:
      Eight lignans were isolated and purified from the flowers of Camellia nitidissima Chi by silica gel, Sephadex LH-20 gel, C18 reversed silica gel, and semi-preparative HPLC. Their structures were determined by NMR and ESI-MS spectroscopic techniques. The structures were elucidated by the spectrum technologies as: eudesmin (1), (+)-diasyringaresinol (2), (+)-isoeucommin A (3), Pinoresinol 4-O-glucoside (4), 7S, 8R, 8’R-(-)-lariciresinol-4’-O-D-glucopyranoside (5), (+)-Isolariciresinol 9-O-β-D-glucopyranoside (6), (+)-Isolariciresinol 9’-O-β-D-glucopyranoside (7), and 3’, 4-O-dimethylcedrusin (8). All of these compounds were isolated from this plant for the first time.
