The catalysts include piperidine and aniline. | Ferulic acid is biosynthesized in plants from caffeic acid by the action of the enzyme caffeate O-methyltransferase. , Although there are many sources of ferulic acid in nature, its bioavailability depends on the form in which it is present: free ferulic acid has limited solubility in water, and hence poor bioavailability. Tomaro-Duchesneau C, Saha S, Malhotra M, Coussa-Charley M, Kahouli I, Jones ML, Labbé A, Prakash S. Pharmaceuticals (Basel). For example, cell suspension culture of sugar beet and corn can obtain water-soluble glucose ester of ferulic acid, sucrose ferulate, etc., and the content can be as high as 20.0unol/g.
