Comparison of High Performance Liquid Chromatography with 1H Nuclear Magnetic Resonance Spectrometry for the Quantitative Analysis of Pyrrolizidine Alkaloids from Senecio Vulgaris

Abstract

A high-performance liquid chromatographic method for the analysis of pyrrolizidine alkaloids from Senecio vulgaris has been developed using narceine-HCl as an internal standard. A reversed phase procedure with a methanol/.01 M KH₂PO₄30/70 solvent system is described, and compared with a quantitative¹H Nuclear Magnetic Resonance spectrometric method. Some advantages and limitations are discussed.
