Seneciphyllinine, a pyrrolizidine alkaloid, is isolated from the roots of Gynura japonica. Pyrrolizidine alkaloids are highly hepatotoxic natural chemicals that produce irreversible chronic and acute hepatotoxic effects on human beings.

Two toxic pyrrolizidine alkaloids were isolated from Senecio leucanthemifolius and six from Senecio rodriguezii. Their structures were determined by spectroscopic methods.
Pyrrolizidine alkaloids from Senecio leucanthemifolius and Senecio rodriguezii.

Six alkaloids were isolated from Gynura segetum (Lour.) Merr. Four of them were identified. Alkaloids I and II were identified as known senecionine and seneciphylline, respectively. Alkaloids III and IV were found to be new compounds named seneciphyllinine and (E)-seneciphylline respectively. Their structures were confirmed on the basis of spectral data (UV, IR, MS, 1HNMR, 13CNMR, C-H COSY).
