【摘要】 从额河千里光Senecio argvnensis Turcz.中首次分得5种吡咯啶型生物碱,经MS,¹H、¹³CNMR,GC-MS及化学方法鉴定为千里光碱（senecionine）、千里光菲灵碱（seneciphyline）和它们的氮氧化物。並通过GC-MS进一步进行了分离、纯化和相对含量的测定。另一个生物碱可能为全缘千里光碱（integerrimine）,因量少未作进一步鉴定。更多还原

【Abstract】 Five pyrrolizidine alkaloids were isolated for the first time from Senecio argunensis Turcz. They were identified as senecionine, seneciphyline and N-oxides by means of spectroscopic data [¹HNMR, ¹³CNMR （DEPT） and capillary GC-MS] and chemical methods. The remaining one, though believed to be integerrimine, was not characteriged due to lack of sufficient amount for further study.更多还原
