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... [Pg.53]

The crude alkaloid preparation from Senecio jacobaea (tangsy ragwort) is converted to pyrrolic derivatives by mammalian liver microsomes. Highest yields were obtained with microsomes from the hamster liver (171, 172). [Pg.381]

Many species of Senecio, such as Senecio jacobaea (ragwort) and Senecio longilobus (thread leaf groundsel), contain hepatotoxic amounts of pyrrolizidine alkaloids (which are covered in a separate monograph). Honey made from Senecio plants also contains pjrrolizidine alkaloids (32). [Pg.364]

An interesting sidelight on the metabolism of pyrrolizidines is that several butterfly and moth larvae that feed on plants containing these alkaloids metabolize them to products that serve the insects as pheromones or defensive substances. Thus the butterfly Idea leuconoe converts alkaloids from Parsonia laevigata to N-oxides [121]. The moth Creatonotos transiens makes its pheromone, R(-)-hydroxydanaidal from7(S)-heliotrine found in its host plant, Senecio jacobaea [122]. [Pg.14]

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. [Pg.154]
