Phenolic acids are one of the most important classes of polyphenols.
They occur naturally in the vegetal world:
- whole grains
- nuts
- coffee
- berries
- tea
These compounds have different functions and are immensely important in the interactions and symbiosis of plants. Phenolic compounds act as signaling molecules and can act as agents in defense of plants (1).
They are found not only in many plants, but also in honey.
Among the phenolic acids we find acids with interesting healing properties.
