Cinnamate and cinnamate derivatives in plants

摘要

Cinnamic acid, an ubiquitous alpha beta unsaturated acid, upon hydroxylation yields p-hydroxy cinnamic acid or p-coumarate, a plant mono phenol. Being, precursor for the production of various di (lignans), polyphenols (lignins) and also substituted derivatives, it seems to be an important aromatic chemical in growth and development of plants. This aromatic chemical substance synthesized primarily by almost all forms of plants, seemingly involves in the regulation of various physiological processes. The presence of this ubiquitous plant alpha beta unsaturated acid and its derivatives have been adopted by plants for various mechanisms. An effort towards the consolidation of these is made here.
