Electrochemical Detection of Alkaloids in HPLC,High-performance liquid chromatography (HPLC) is a valuable tool in plant analysis, due to its high power of resolution and compatibility for the determination of nonvolatile and thermally labile compounds. Therefore HPLC has often been applied in the determination of alkaloids (Verpoorte et al. 1984; Popl et al. 1990).
