Abstract
Abstract Datura innoxia plants were fed via the roots with cinnamic acid-[2 14 C], (±)-phenyllactic (2-hydroxy-3-phenylpropanoic) acid-[2 14 C] and phenylalanine-[2- 14 C]. In each case apohyoscine, hyoscine, hyoscyamine and littorine were isolated from the aerial parts, and hyoscine, hyoscyamine and littorine from the roots. Cinnamic acid was not incorporated into the acid moieties of the alkaloids. Phenyllactic acid served as a better precursor than phenylalanine for tropic acid (hyoscine and hyoscyamine) and atropic acid (apohyoscine). Phenylalanine served as an effective precursor for the phenyllactic acid moiety of Littorine.
