| 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. |
