Alkaloids from Senecio aegyptius and S. desfontainei.
Otosenine and senecionine/seneciphyllme were isolated from Senecio aegyptius and S. desfontainei, respectively. Senecionine and seneciphylline easily cocrystallize; m.p. and IR-spectra of mixtures of both alkaloids and their separation by PC are described. IR evidence of individual alkaloids and of the alkaloid-pair are shown.
