About 28 quinolizidine alkaloids and the dipiperidine alkaloids am modendrine, dehydroammodendrine and N -formylammodendrine were identified in the alkaloidal extracts of Retama raetam, Retama sphaerocarpa and Retama monosperma by capillary GLC and GLCMS. Alkaloid profiles of the three Retama species with a Mediterranean distribution are more similar than alkaloid patterns of different organs of the same plant. Whereas sparteine and retamine are the major components of stems, lupanine, retam ine, N-methylcytisine and cytisine dominate in flowers and pods, and cytisine in seeds indicating a high degree of organ specificity of alkaloid storage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
