摘要: 从棉毛橐吾(Ligularia vellerea)根茎中分离得到2个查尔酮和1个黄酮类化合物:3,2′, 4′-三羟基-4-甲氧基-查尔酮(1)、4,2′,4′-三羟基-查尔酮(2)和7,3′-二羟基4′-甲氧基黄酮(3). 应用1D和2D NMR(包括1H-1H COSY、HSQC和 HMBC)对这3种化合物的结构进行了分析,确认了化合物1和3中甲氧基和羟基及化合物2中羟基的连接位置,并对它们的1H和13C的化学位移进行了全归属. 

Abstract: Two chalcones and one flavonone were isolated from the rhizomes of Ligularia vellerea: 3, 2′, 4′-trihydroxy-4-methoxy-chalcone (1), 4, 2′, 4′-trihydroxy-chalcone (2) and 7, 3′-dihydroxy-4′-methoxy flavonoe (3). The structures of these three compounds were elucidated by 1D and 2D NMR (including 1H-1H COSY、HSQC and HMBC). The positions of the methoxyl and the hydroxyl groups in each compound were determined.

Key words: NMR, assignment, 2D NMR, Ligularia vellerea, flavonoids
