Investigation into the Metabolism of Phenyllactic Acid in Datura Stramonium.
Abstract
The administration of phenyllactic acid (l,3-C) to Datura.stramonium plants
yielded labelled Hyoscyamin and hyoscine. proton noise decoupled CNMR spectra of
13 13 these alkaloids revealed the presence of satellite peaks, due to C-C spin-spin
coupling, symmetrically located about the singlet peaks arising from C. and C of the tropic acid moiety of these alkaloids. This result indicated that the rearr¬angement of phenyllactic acid to tropic acid involves an intramolecular migration of the carboxyl group.
