| 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. |
