## Abstract From analysis and refinement by the LAOCOON III program of the 220 MHz ^1^H spectrum of 2,2โฒโbiquinoline, recorded as a saturated solution in carbon disulphide, most derived chemical shifts and coupling constants are close to corresponding values in quinoline. However, Hโ3 is at 1.5 ppm

## Abstract The ^1^H and ^13^C NMR spectra of the pyrrolizidine alkaloid 13โ__O__โacetyldicrotaline were studied at 4.7 T. A full assignment of the ^1^H and ^13^C signals was achieved by application of a variety of NMR techniques, including homonuclear ^1^H NOE difference, 2D ฮด~H~/ฮด~H~ phaseโsensit
A method for the determination of the pyrrolizidine alkaloids from Seneciojucobueu (Compositae) by 'H and I3C NMR is presented. 'H NMR is a reliable method for the determination of the total alkaloid level. I3C NMR appears to be a suitable method for the determination of the individual alkaloids. Th
