Stability Hygroscopic
Applications Caffeic Acid is a constituent of plants, probably occurs in plants only in conjugated forms. Caffeic acid is found in all plants because it is a key intermediate in the biosynthesis of lignin, one of the principal sources of biomass. Caffeic acid is one of the main natural phenols in argan oil.

Caffeic acid

CAS: 331-39-5

Caffeic acid is naturally produced by the metabolism of plants and fungi. Caffeic acid has an antioxidant activity that can be higher than tocopherol in oil-in-water emulsions. Caffeic acid has proven antimicrobial activity against Staphylococcus aureus. In mice, caffeic acid inhibits the enzyme 5-lipoxygenase thus inhibititing the biosynthesis of the inflammatory mediators leukotrienes.
