On the distribution of caffeic acid and the chlorogenic acid isomers in plants
Archives of Biochemistry and Biophysics, 1958Abstract 1. 1. The silicic acid column technique described by Bulen et al. (9) has been used in a study of the distribution of caffeic acid and chlorogenic acid isomers in plants. Ultraviolet-absorption measurements and titration with alkali were used for the detection of these acids. 2. 2. Resolution into five bands was achieved.

Antioxidant activity of caffeic acid (3,4-dihydroxycinnamic acid)
Toxicology, 2006Caffeic acid (3,4-dihydroxycinnamic acid) is among the major hydroxycinnamic acids present in wine; sinapic acid, which is a potent antioxidant. It has also been identified as one of the active antioxidant. In the present study, the antioxidant properties of the caffeic acid were evaluated by using different in vitro antioxidant assays such as 2-azino ...

Applied Catalysis B: Environmental, 2016
Abstract The photoisomerization of trans-caffeic acid to cis-caffeic acid has been studied in the presence of N2 in homogeneous aqueous solutions and in suspensions of various TiO2 catalysts. The results supported the hypothesis of an energy transfer process from TiO2 to the substrate due to the recombination of the photogenerated electron–hole pairs.

Antitumor effect of propolis : a comparison with caffeic acid and caffeic acid phenethyl ester
1999The antitumor effect of a water soluble derivative of propolis (WSDP) caffeic acid (CA) and caffeic acid phenethyl ester (CAPE), components of natural propolis, were investigated. The oral administration of these compounds (50 mg/kg or 150 mg/kg) given before or after tumor cell inoculation supressed tumor growth of a weakly immunogeneic mammary ...
