Abstract
Hydroxycinnamic acids, such as p-coumaric acid and ferulic acid, are a major class of compounds derived from the phenylpropanoid pathway. These compounds are widely conserved in plants and primarily accumulate in the secondary cell wall. They serve as important structural components that contribute to the overall strength and rigidity of plant cell walls and are also potent antioxidants valued for nutritional consumption. This protocol describes a method for analyzing hydroxycinnamic acids that are released after incubation under alkaline conditions.
