Hepatotoxic pyrrolizidine alkaloids in Emilia sonchifolia from Taiwan[Reference: WebLink]

METHODS AND RESULTS:
Otonecine bases, senkirkine, Otosenine, neosenkirkine, petasitenine, acetylsenkirkine, desacetyldoronine, acetylpetasitenine, and doronine. Quantification of the individual PAs was determined by six-point linear regression curves in the range of 25–400 μg/mL of senkirkine and senecionine.

Spasmolytic properties of pyrrolizidine alkaloids[Pubmed: 488324]

METHODS AND RESULTS:
Acute toxicity, spasmolytic and hypotensive properties of the alkaloids senecionine, d-otocenine and floridanin isolated from Senecio Erraticum L. were studied.
CONCLUSIONS:
D-Otocenine and floridanin elicited low toxicity, while senecionine and d-Otosenine showed spasmolytic and floridanin predominantly hypotensive properties.
