利用正相硅胶、反相硅胶和HPLC等色谱手段进行化学成分的分离,从铁包金乙酸乙酯提取物中分离得到9个化合物。化合物经波谱分析鉴定为5-hydroxy-7-(2’-hydroxypropyl)-2-methyl-chromone(1)、(-)-(1’R,2’S)-erythro-5-hydroxy-7-(1’,2’-dihydroxypropyl)-2-methyl-chromone(2)、柚皮素(3)、圣草酚(4)、(+)-香橙素(5)、(+)-花旗松素(6)、(+)-儿茶素(7)、(+)-表没食子儿茶素(8)和槲皮素(9)。其中化合物2为新的色原酮衍生物,化合物1为首次从该属植物中分离得到。化合物3～9为黄酮类化合物,为首次从该种植物中分离得到。
The chemical constituents were separated by chromatography on silica gel, reversed-phase silica gel and HPLC. Nine compounds were isolated from the ethyl acetate extract of iron-ferro gold. The compounds were identified as 5-hydroxy-7- (2’-hydroxypropyl) -2-methyl- chromone (1), (-) - (1’R, 2’S) -erythro-5-hydroxy-7- (2), naringenin (3), eriodictyol (4), (+) - orange (5), (+) - taxifolin 6), (+) - catechin (7), (+) - epigallocatechin (8) and quercetin (9). Among them, compound 2 is a new chromone derivative, and compound 1 was isolated from this genus for the first time. Compounds 3 to 9 are flavonoids, isolated from this plant for the first time.
