WebA derivatization procedure and a high-performance liquid chromatographic (HPLC) method of analysis for pilocarpine are described. The method is based on the quaternization of the 3'-tertiary amino group of the methylimidazole ring of pilocarpine with p-nitrobenzyl bromide. WebDiverse chromatographic methods exist for the analysis of pilocarpine, mainly for the purpose of quality control of eye drops. Most of the analytical methods applied to the quantification of pilocarpine employ HPLC with either octadecyl [8,9], phenyl [10,11] or cyclodextrin [12] columns and UV detection.
