title: Cellular localization of quinolizidine alkaloids by laser desorption mass spectrometry (LAMMA 1000).
abstract: Stem sections of Lupinus polyphyllus and Cytisus scoparius have been analyzed for the distribution of quinolizidine alkaloids by laser desorption mass spectrometry, employing a LAMMA 1000 instrument. Sparteine and lupanine could be recorded and were found to be restricted to the epidermis and probably also to the neighbouring 1 or 2 subepidermal cell layers.
