Senecio cineraria

Egyptian Senecio cineraria DC. produces senecionine, seneciphylline, jacobine and otosenine as a mixture of the free bases and the AT-oxides. ... 

Jacobine was extracted from Senecio jacobaea in 0.03% yield from plants which had been collected in June and in 0.05-0.06% yield from plants which had been collected in July and August. It was also obtained, in 0.05% yield, along with jacodine, from Senecio cineraria collected in June.

A new minor constituent of Senecio jacobaea L. has been shown to contain chlorine from its mass spectrum, which showed a molecular ion at m/z 38-5 and an ion at m/z 350 due to loss of chlorine.31 Senkirkine and integerrimine were previously isolated from S. antieuphorbium Sch. Bip. (c/. Vol. 3, p. 84). Senaet-nine and isosenaetnine have now been found in this species.32 Otosenine has again been isolated from S. cineraria DC.33 Bulgarian 5. erucifolius produces senecionine and seneciphylline.34 The amount of senkirkine present in specimens of Tussilago farfara obtained from several countries has been determined.35...
