中文摘要:

姜花（ Hedychium coronarium Koen）根茎用甲醇提取，利用硅胶柱层析、Sephadex LH-20 柱层析、薄层层析及HPLC等手段对其化学成分进行分离纯化，得到5个化合物，经波谱解析和对其理化性质进行对比，鉴定为3个二芳基庚烷和2个黄酮，分别是gingerenone A（1 1），rel-（3 R ，5 S ）-3， 5-dihydroxy-1-（4-hydroxy-3-methoxyphenyl）-7-（4-hydroxyphenyl）-heptane（2 2），hexahydrocurcumin （3 3），3，5，7，4´-tetramethoxyflavone（4 4）和5-hydroxy-3，7，4´-trimethoxyflavone（5 5）。化合物1 1～4 4为首次从姜花中分离得到。

英文摘要:

Five compounds were isolated from the methanol extract of the rhizomes of Hedychium coronarium Koen by sili⁃ ca gel column chromatography, Sephadex LH-20 chromatography, thin layer chromatography and high performance liquid chromatography. Their structures were identified by spectroscopic analysis combined with their physicochemical data. Three diarylheptanes and two flavonoids were identified as gingerenone A (1), rel-(3R,5S)-3,5-dihydroxy-1-(4-hydroxy- 3-methoxyphenyl)-7-(4-hydroxyphenyl)-heptane (2), hexahydrocurcumin (3), 3,5,7,4´-tetramethoxyflavone (4) and 5-hy⁃ droxy-3,7,4´-trimethoxyflavone (5). Compounds 1～4 were isolated from this plant for the first time.
