Through the work of Segall et ai, improved separations of mixtures of pyrrolizidine alkaloids have been obtained by high performance liquid chromatography 234, 272, 274). The iV-Oxides are also amenable to this treatment 301). The best separations were achieved on reverse-phase systems 103, 273). [Pg.133]
