Description and Uses

Caffeic acid is abundant in the whole plant of Solidago decurrens Lour. (Yi Zhi Huang Hua), fruit of Crataegus pinnatifida Bge. var. major N.E.Br. (Shan Li Hong), Salix myrtillacea Anderss. (Po Liu), rhizome of Cimicifuga foetida L., rhizome of Polypodiaceae Polypodium vulgare L. (Ou Ya Shui Long Gu), peel of Rutaceae Citrus limonum (Ning Meng), the whole plant of Polygonaceae Polygonum aviculare L. (Pian Xu), root of Valeriana officinalis L. (Xie Cao), the whole plant of Thymus mongolicus Ronn (She Xiang), leaves of Eucommia ulmoides (Du Zhong), and other herbal plants. It is a kind of polyhydroxy styrene acid, with the general chemical properties of phenolic acid. It is easily oxidized for the reason of the unsaturated double bonds, particularly unstable in alkaline solution
Caffeic acid has both cis and trans isomers, and the two isomers of caffeic acid have a mutual transformation in plants, which may regulate some important physiological process. Caffeic acid exists in plants in the main form of complexes; free state accounts for a few proportion.

antineoplastic, PGE2 synthase inhibitor, PK inhibitor
