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。
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.
