Determination of caffeine in coffee products by dynamic complexation with 3,4-dimethoxycinnamate and separation by CZE.

Thiago Nogueira et al.

Electrophoresis, 28(19), 3570-3574 (2007-09-05)

A method based on the formation of pi-complexes with chlorogenate-like species was proposed for the determination of caffeine in regular (nondecaffeinated) and decaffeinated coffee. Both caffeate and 3,4-dimethoxycinnamate were able to transform caffeine--a neutral species in aqueous solutions--into an anionic

Absorption of dimethoxycinnamic acid derivatives in vitro and pharmacokinetic profile in human plasma following coffee consumption.

Tracy L Farrell et al.

Molecular nutrition & food research, 56(9), 1413-1423 (2012-08-07)

This study reports the 24 h human plasma pharmacokinetics of 3,4-dimethoxycinnamic acid (dimethoxycinnamic acid) after consumption of coffee, and the membrane transport characteristics of certain dimethoxycinnamic acid derivatives, as present in coffee. Eight healthy human volunteers consumed a low-polyphenol diet
