目的:研究菊科植物大叶橐吾的化学成分。方法:采用硅胶柱色谱进行分离纯化,通过理化性质和波谱数据分析鉴定化合物结构。结果:分离得到8个化合物,分别鉴定为:山奈酚(1)、2,4′-二羟基-5-甲氧基查尔酮(2)、5-羟基-3,4′,7-三甲氧基黄酮醇(3)、isobutyl ester terephthalic acid(4)、4-hydroxybenzaldehyde(5)、mono(2-eth-ylhexyl)terephthalate(6)、羽扇豆醇(7)和β-谷甾醇(8)。结论:化合物1~7为首次从该植物中分离得到。
Objective: To study the chemical composition of Asteraceae. Methods: The compounds were isolated and purified by silica gel column chromatography. The structures of compounds were identified by physico-chemical properties and spectral data analysis. Results: Eight compounds were isolated and identified as kaempferol (1), 2,4’-dihydroxy-5-methoxychalcone (2), 5-hydroxy- Isobutyl ester terephthalic acid (4), 4-hydroxybenzaldehyde (5), mono (2-eth-ylhexyl) terephthalate (6) . Conclusion: Compounds 1 ~ 7 were isolated from this plant for the first time.
