Phenolics, which occur widely in plants, encompass a wide range of structural classes and impart biological function to plants. They have been investigated in plants as anti-stress compounds, biosynthesized in response to abiotic and biotic stress such as pathogen attack, heavy metal, UV irradiation, and chemical stressors. In many cases, particularly for plant-metabolites interactions, analytical methods of stress driven phenolics have been intensively studied. This review focus on methodological aspects on the determination of plant defensive phenolics in response to environmental stress with a special emphasis on methods for elicitation, analysis and structural elucidation.
