目的研究萎蒿Artemisia selengensis全草的化学成分。方法运用各种柱色谱方法分离纯化,通过理化性质及波谱分析技术鉴定化合物的结构。结果从蒌蒿全草醋酸乙酯部位分离得到11个化合物,分别鉴定为反式白藜芦醇(1)、反式肉桂酸(2)、咖啡酸(3)、绿原酸(4)、没食子酸(5)、木犀草素(6)、异鼠李素(7)、7-甲氧基香豆素(8)、槲皮素(9)、毛蕊花糖苷(10)、7-甲氧基-4’-羟基异黄酮(11)。结论化合物1~11均为首次从该植物中分离得到。 Objective To study the chemical constituents of Artemisia selengensis. Methods The compounds were separated and purified by various column chromatographic methods. The structures of the compounds were identified by physicochemical properties and spectral analysis. Results Eleven compounds were isolated from the whole ethyl acetate fraction of Artemisia selengensis and identified as trans resveratrol (1), trans-cinnamic acid (2), caffeic acid (3), chlorogenic acid Gallic acid (5), luteolin (6), isorhamnetin (7), 7-methoxycoumarin (8), quercetin (9), verbascoside (10) 4’-hydroxyisoflavone (11). Conclusion Compounds 1 ~ 11 were isolated from this plant for the first time.
