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.

A simple, sensitive, and accurate liquid chromatographic method with electrochemical detection (ECD) has been developed for analysis of caffeic acid and caffeic acid phenyl ester in propolis. ECD is more sensitive than diode-array detection for analysis of the two phenolic compounds.

Caffeic acid phenethyl ester (CAPE) is a bioactive polyphenolic compound obtained from propolis extract. Although it has a broad therapeutic potential, the bioavailability of CAPE is limited, due to reduced solubility and poor plasmatic stability. Efforts to reduce these pharmacokinetic drawbacks resulted in the synthesis of caffeic acid phenethyl ...

Reaction of caffeic acid derivatives with acidic nitrite
Tetrahedron Letters, 2001Abstract Caffeic derivatives were reacted with acidic nitrite at controlled pH in order to mimic the gastric juice conditions. At pH 2, whereas caffeic acid reacts exclusively on the side chain, its esters are readily nitrated. Under more acidic conditions (pH 1), caffeic acid methyl ester undergoes a dimerisation into a norlignan derivative.

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 ...
