title: [Spasmolytic properties of pyrrolizidine alkaloids].
abstract: Acute toxicity, spasmolytic and hypotensive properties of the alkaloids senecionine, d-otocenine and floridanin isolated from Senecio Erraticum L. were studied. D-otocenine and floridanin elicited low toxicity, while senecionine and d-otosenine showed spasmolytic and floridanin predominantly hypotensive properties.
