川鄂金丝桃的化学成分研究

Study on chemical components of Hypericum wilsonii N. Robson

    摘要
  • 摘要: 综合应用大孔树脂柱层析、正相硅胶柱层析、葡聚糖凝胶色谱、高效液相色谱等多种分离方法从川鄂金丝桃石油醚部位（HW-PE）中分离得到15个化合物，运用现代波谱技术分别鉴定为folecitin( 1 )、表儿茶素 ( 2 )、β-谷甾醇 ( 3 )、β-胡萝卜素 ( 4 )、白桦脂酮酸 ( 5 )、单棕榈酸甘油 ( 6 )、1, 7-二甲氧基-3, 6-二羟基氧杂蒽酮( 7 )、3, 4-二羟基-2-甲氧基氧杂蒽酮 ( 8 )、27-epifurohyperforin isomer 1 ( 9 )、uralione H ( 10 )、attenuatumione E ( 11 )、sampsonione K ( 12 )、attenuatumione C ( 13 )、hypersampsonone C ( 14 )和otogirinin B ( 15 ). 化合物1～15是首次从川鄂金丝桃中分离得到，是首次报道川鄂金丝桃的化学成分，研究丰富了金丝桃属植物的化学成分.

     

    Abstract: A comprehensive application of macroporous resin column chromatography, positive phase silica gel column chromatography, Sephadex LH-20 column chromatography, HPLC, and other separation methods led to 15 compounds be seperated from the petroleum ether fraction of Hypericum wilsonii N. Robson (HW-PE). By using modern spectroscopy techniques, these 15 compounds were identified as folecitin( 1 ),epicatechin( 2 ), β-sitosterol( 3 ), β-carotene( 4 ), betulinicaicd( 5 ), glycerol monopalmitate( 6 ), 1,7-dimethoxy-3,6-dihydroxyxanthone( 7 ), 3,4-dihydroxy-2-methoxyxanthone( 8 ), 27-epifurohyperforin isomer 1( 9 ), uralione H( 10 ), attenuatumione E( 11 ), sampsonione K( 12 ), attenuatumione C( 13 ), hypersampsonone C( 14 ) and otogirinin B( 15 ). This is the first report on the chemical constituents from Hypericum wilsonii N.Robson.
