Common Name | Caffeic acid |

Description | Caffeic acid, also known as caffeate, belongs to the class of organic compounds known as hydroxycinnamic acids. Hydroxycinnamic acids are compounds containing an cinnamic acid where the benzene ring is hydroxylated. Caffeic acid exists in all living species, ranging from bacteria to humans. It is the precursor to ferulic acid, coniferyl alcohol, and sinapyl alcohol, all of which are significant building blocks in lignin. Outside of the human body, caffeic acid has been detected, but not quantified in fats and oils and nuts. Caffeic acid is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound. Caffeic acid has a variety of potential pharmacological effects in in vitro studies and in animal models, and the inhibitory effect of caffeic acid on cancer cell proliferation by an oxidative mechanism in the human HT-1080 fibrosarcoma cell line has recently been established. It occurs at high levels in black chokeberry (141 mg per 100 g) and in fairly high level in lingonberry (6 mg per 100 g). |
