摘要:
研究了三叶鬼针草Bidens pilosa L.全草的化学成分.利用各种色谱和波谱方法分离并鉴定了13个黄酮类化合物,分别:2′-hydroxy-4,4′-dimethoxy-chalcone (1),isoliquiritigenin (2),3,2′,4′-trihydroxy-4-methoxy-chalcone (3),licochalcone A (4),4 ′-O-β-D-glucopyranosyl-2′,3-dihydroxy-4-methoxy-chalcone (5),butein (6),apigenin (7),luteolin (8),diosmetin (9),chrysoeriol (10),3,5,6,7,3′,4′,5′-heptamethoxyflavone (11),7-O-β-D-glucopyranosyl-5,3′-dihydroxy-3,6,4′-trimethoxyflavone (12),sulfuretin (13).化合物1-5,9,11均为首次从鬼针草属植物中分离得到.
