    摘要:

    通过正相硅胶、反相硅胶、大孔吸附树脂、Sephadex LH-20和高效液相色谱等多种现代色谱技术对番荔枝科紫玉盘属植物大花紫玉盘(Uvaria grandiflora)干燥根的化学成分进行系统地分离纯化,得到12个化合物,用现代波谱技术确定化合物的结构分别为:epicatechin-(4β→1′,2→O→2′)-phloroglucinol(1),proanthocyanidin A-1(2),proanthocyanidin A-2(3),表儿茶素(epicatechin)(4),phlorizin(5),圣草酚(eriodictyol)(6),erythro-guaiacylglycerol-8-O-4′-(coniferyl alcohol)ether(7),threo-guaiacylglycerol-8-O-4′-(coniferyl alcohol)ether(8),erythro-guaiacylglycerol-8-O-4′-(sinapyl alcohol)ether(9),threo-syringylglycerol-8-O-4′-(sinapyl alcohol)ether(10),burselignan(11),icariol A2(12)。化合物1~12均为首次从该植物中分离得到,其中化合物1为新天然化合物。

    Abstract:

    Chemical investigation of the roots of Uvaria grandiflora by repeated column chromatography(CC)over silica gel, ODS, Sephadex LH-20, and HPLC resulted in the isolation of twelve compounds. Their structures were identified as: epicatechin-(4β→1′, 2→O→2′)-phloroglucinol(1), proanthocyanidin A-1(2), proanthocyanidin A-2(3), epicatechin(4), phlorizin(5), eriodictyol(6), erythro-guaiacylglycerol-8-O-4′-(coniferyl alcohol)ether(7), threo-guaiacylglycerol-8-O-4′-(coniferyl alcohol)ether(8), erythro-guaiacylglycerol-8-O-4′-(sinapyl alcohol)ether(9), threo-syringylglycerol-8-O-4′-(sinapyl alcohol)ether(10), burselignan(11)and icariol A2(12). Compounds 1 to 12 were all isolated from this plant for the first time, and compound 1 was a new natural product.
