Vanillic acid (4-hydroxy-3-methoxybenzoic acid) is a dihydroxybenzoic acid derivative used as a flavoring agent. It is an oxidized form of vanillin. It is also an intermediate in the production of vanillin from ferulic acid. [2] [3]

Occurrence in nature

The highest amount of vanillic acid in plants known so far is found in the root of Angelica sinensis, [4] an herb indigenous to China, which is used in traditional Chinese medicine.

Occurrences in food

Açaí oil, obtained from the fruit of the açaí palm ( Euterpe oleracea), is rich in vanillic acid (1616±94 mg/kg). [5] It is one of the main natural phenols in argan oil.[ citation needed] It is also found in wine and vinegar. [6]

Metabolism

Vanillic acid is one of the main catechins metabolites found in humans after consumption of green tea infusions. [7]

Synthesis

Vanillic acid can be obtained from the oxidation of vanillin by various oxidizing agents. With Pd/C, NaBH4, and KOH as the oxidizing agent, the conversion was reported to occur in ~89% yield. [8]
