Abstract

Two imidazole alkaloids (I&II) have been isolated from the seeds of Lepidium sativum L. Compound I O-demethyllepidine was isolated for the first time and its structure was elucidated on the basis of spectral analysis, while compound II was identified as lepidine and its identification was confirmed by X-ray crystallography.
