In vitro cultures of Argemone mexicana (Papaveraceae) were induced from leaves of mature plants. Sanguinarine, a benzophenanthridine, was the main alkaloid in the cultures, even in the absence of inducers of secondary metabolism. The accumulation of this metabolite was increased by adding methyl jasmonate and fungal elicitors, although in a limited fashion in comparison to other sanguinarine-producing species. Evidence of a transport mechanism, which may be related to the magnitude of the response, was obtained based on the fluorescent properties of bezophenathridines in the elicited cultures.
