Alkaloid profiles of five Senecio species (Asteraceae), including S. ambiguus subsp. ambiguus, S. ambiguus subsp. nebrodensis, S. gibbosus subsp. bicolor, S. gibbosus subsp. gibbosus, and S. gibbosus subsp. cineraria, were studied. Eleven pyrrolizidine alkaloids were identified and their content was evaluated by GLC-MS and GLC analysis. Otosenine and florosenine were found to be the major alkaloids in all studied species. It is interesting that only S. ambiguus subsp. nebrodensis was characterized by a high content of the alkaloids jacobine, jacoline, jaconine, and jacozine.
对5种千里光属植物（菊科）的生物碱谱进行了研究，包括两形千里光亚种两形千里光、两形千里光亚种内布罗地千里光、驼背千里光亚种双色千里光、驼背千里光亚种驼背千里光和驼背千里光亚种灰叶千里光。鉴定出11种吡咯里西啶生物碱，并通过气相色谱-质谱联用仪（GLC-MS）和气相色谱（GLC）分析对其含量进行了评估。发现奥索千里光碱和弗洛罗千里光碱是所有研究物种中的主要生物碱。有趣的是，只有内布罗地千里光亚种的特征是含有高含量的生物碱雅可宾、雅可林、雅可宁和雅可嗪。
