Hydroxycinnamic acids (hydroxycinnamates) are a class of Aromatic acids or phenylpropanoids having a C6-C3 skeleton. These compounds are hydroxy derivatives of cinnamic acid.
In the category of phytochemicals that can be found in food, there are :
- α-Cyano-4-hydroxycinnamic acid
- Caffeic acid – burdock, hawthorn, artichoke, pear, basil, thyme, oregano, apple
- Cichoric acid
- Cinnamic acid – aloe
- Chlorogenic acid – echinacea, strawberries, pineapple, coffee, sunflower, blueberries
- Diferulic acids
- Coumaric acid
- Coumarin – citrus fruits, maize
- Ferulic acid (3-methoxy-4-hydroxycinnamic acid) – oats, rice, artichoke, orange, pineapple, apple, peanut
- Sinapinic acid (3,5-dimethoxy-4-hydroxycinnamic acid or sinapic acid)
Hydroxycinnamoyltartaric acids
- Caftaric acid – grape and wine,[1] mainly trans isomer[2]
- Coutaric acid – grape and wine, both trans and cis isomers [2]
- Fertaric acid – grape and wine, mainly trans isomer [2]
