Capillary gas chromatography fourier transform ir spectroscopy of pyrrolizidine alkaloids of senecio inaequidens dc



Capillary gas chromatography fourier transform ir spectroscopy of pyrrolizidine alkaloids of senecio inaequidens dc



Journal of Chromatography 473(1): 161-170



The pyrrolizidine alkaloid (PA) fraction of Senecio Inaequidens DC, was studied by capillary gas chromatography-Fourier transform infrared spectroscopy. The vapour-phase IR spectra of PAs and the advantages and disadvantages of this combined technique for their structure elucidation in complex mixtures are discussed. Examples of the distinction between necine bases (retronecine and otonecine) and geometric isomers (senecionine and integerrimine) are given.
