Phytochemical investigation of Senecio obtusatus Wall. ex DC led to the isolation of a novel alkaloid, senobtusin (1). Compound 1 possesses an atypical amidine moiety, and the structure was determined on the basis of extensive NMR analysis and HR-ESI-MS technique. This is the first report of this class of natural products obtained from family Asteraceae, and the systematic importance was also discussed.
对钝叶千里光（Senecio obtusatus Wall. ex DC）进行植物化学研究，从中分离出一种新型生物碱，即钝叶千里光碱（1）。化合物1具有一个非典型的脒基部分，其结构通过广泛的核磁共振分析和高分辨电喷雾电离质谱技术得以确定。这是从菊科植物中获得的此类天然产物的首次报道，同时也讨论了其系统重要性。
