The biosynthesis of Lobelia alkaloids. Part II. The role of lobelanine in the biosynthesis of lobeline
Abstract
Administration of [N-methyl-14C]lobelanine to Lobelia inflata plants gave [N-methyl-14C]lobeline (12% incorporation), suggesting the former alkaloid to be the symmetrical intermediate involved in the biosynthesis of lobeline from phenylalanine and lysine.
