摘要: 从款冬花(Tussilago farfara L.) 中分离得到四个倍半萜类化合物和两个苯二甲酸酯类化合物, 经光谱分析确定其中两个倍半萜类化合物为新结构, 命名为款冬花酮(tussilagonone, 1) 和新款冬花内酯(neotussilago lactone, 2). 由血小板活化因子(PAF) 引起的血小板聚集实验结果表明, 两个新化合物均有较强的抑制PA F 活性。

Abstract: Two new sesquiterpenes, named tussilagonone (1) and neotussilagolactone (2), together with two known sesquiterpenes (3) and (4) and two phthalic acid derivatives (5) and (6), were isolated from the flower buds of Tussilago farfara . The structures of (1) and (2) were determined on the basis of spectroscopic analyses. Compounds (1) and (2) exhibited activities against platelet aggregation caused by platelet activating factor.

Key words: Tussilago farfara, Sesquiterpenes, Tussilagonone, Neotussilagolactone, PAF inhibitors
