DARU Journal of Pharmaceutical Sciences12Investigation into the Metabolism of Phenyllactic Acid in Datura Stramonium.8184Morteza Ansarin20151006The administration of phenyllactic acid (l,3-C) to Datura.stramonium plantsyielded labelled Hyoscyamin and hyoscine. proton noise decoupled CNMR spectra of13 13 these alkaloids revealed the presence of satellite peaks, due to C-C spin-spincoupling, 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.https://daru.tums.ac.ir/index.php/daru/article/view/12https://daru.tums.ac.ir/index.php/daru/article/download/12/12
