摘要
本文利用大孔树脂色谱及高速逆流色谱等方法,从杏香兔耳风的全草中分得两个化合物,经IR,MS,1H-NMR,13C-NMR等光谱鉴定分别为3,5-二咖啡酰基奎宁酸和4,5-二咖啡酰基奎宁酸.两个化合物均首次从该属植物中得到.
Two dicaffeoylquinic acids, namely 3,5-dicaffeoylquinic acid and 4, 5-dicaffeoylquinic acid, were isolated from Ainsliaea fragrans Champ by means of extraction, chromatography on macroporous resin and high-speed counter-current chromatography, and their structures were elucidated on the basis of spectral analyses （IR, MS, ^1H-NMR, ^13C-NMR）. Two compounds were obtained from the plants of Ainsliaea fiagrans for the first time.
