Provided are methods or processes for producing ferulic acid from a plant material, for example, a rice bran or its derivatives. Provided are methods comprising an ion swapping and solvent extraction process followed by a chromatographic separation operations that are coupled into a process which functions to recover a fraction rich in gamma-oryzanol, thus enabling the subsequent production of a high purity ferulic acid. Provided are methods comprising an ion swapping and solvent extraction process followed by a process which functions to recover a fraction rich in gamma-oryzanol, or a mixture of ferulic acid esters of phytosterols and triterpenoids, optionally comprising cycloartenyl ferulate, 24-methylenecycloartanyl ferulate, and/or campesteryl ferulate, to enable the production of a high purity ferulic acid. Provided are methods comprising a saponification and solvent extraction process followed by recovering a fraction rich in gamma-oryzanol to enable the production of a high purity ferulic acid.
