中文摘要:
      风干粉碎后的红姜花(Hedychium coccineum)根茎用工业甲醇浸提,甲醇浸提物用乙酸 乙酯-水萃取。采用多种分离技术(硅胶柱层析、Sephadex LH-20、RP-18柱层析、HPLC)分离乙酸 乙酯浸膏中的化学成分,通过NMR等方法对所得的化合物进行结构鉴定。共鉴定6个黄酮类化合 物,分别是 5-hydroxy-3,7,4’-trimethoxyflavone (1)、3,5-dihydroxy-7,4’-dimethoxyflavone (2)、 kaempferol-4’-O-methylether (3)、ermanin (4)、dihydrokaempferide (5)、aromadendrin-7,4'-dimethyl ether (6)。均为首次从红姜花中分离得到。
英文摘要:
      The air-dried and crushed rhizomes of Hedychium coccineum were extracted with MeOH, and the extract was partitioned with EtOAc-H2O. The EtOAc extract was isolated by various separation techniques (Silica gel, Sephadex LH- 20, RP-18 column chromatography and HPLC). By means of spectroscopic analysis, the isolated compounds were identi⁃ fied as 5-hydroxy-3,7,4'-trimethoxyflavone (1), 3,5-dihydroxy-7,4'-dimethoxyflavone (2), kaempferol-4'-O-methylether (3), ermanin (4), dihydrokaempferide (5) and aromadendrin-7,4'-dimethyl ether (6). All the compounds were isolated from H. coccineum for the first time.
