title: Imidazole alkaloids from Lepidium meyenii.
abstract: Two new imidazole alkaloids (lepidiline A and lepidiline B) have been isolated from a root extract of Lepidium meyenii with the common name Maca and identified as 1,3-dibenzyl-4,5-dimethylimidazolium chloride (1) and 1,3-dibenzyl-2,4,5-trimethylimidazolium chloride (2), respectively. The structures of these two new compounds were determined by spectroscopic methods, as well as single-crystal X-ray diffraction performed on compound 1.
