On enzyme inhibition by oxidized chlorogenic acid
Life Sciences, 1964Abstract The inhibiting action of oxidized chlorogenic acid (Ox-CGA) on the activity of several enzymes has been investigated. A comparative analysis of the effects of Ox-CGA with those of p-hydroxy-mercuri-benzoate seems to exclude the -SH groups of the proteins as the main site of action of Ox-CGA.

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.
