This paper summarizes progress made in using Larrea divaricata Cav. cell cultures for the production of the cytotoxic lignan nordihydroguaiaretic acid (NDGA) and the phenylpropanoids p-coumaric acid, ferulic acid and sinapyl alcohol. In order to improve the biomass formation and production of these phenolic compounds, four precursors (l- phenylalanine, cinnamic acid, ferulic acid, and sinapic acid) were fed to L. divaricata cell ...
