Anal. Chim. Acta 566 (2), 157-166 (2006). Extraction of pyrrolizidine alkaloids from the alkalised crude extract of Symphytum cordatum (L.) W.K. roots as free tertiary bases and polar N-oxides by one-step liquid–liquid partitioning and pre-fractionation by preparative multiple-development TLC on silica gel with chloroform – methanol – 25 % ammonia 50:5:1. Three alkaloid fractions of different polarities were obtained which showed different retention on silica gel: the most polar N-oxides had the highest retention, the tertiary bases had medium retention, and diesterified N-oxides had the lowest retention. Purification of the former fraction, which was reduced into free bases by sodium hydrosulfite, by liquid-liquid partitioning on Extrelut-NT3 cartridge. Further analysis by HPLC – ion-trap MS.
