A method is proposed for the simultaneous determination of total chlor
ogenic acid (CGA), trigonelline and caffeine in green coffee using hig
h performance gel filtration chromatography. The method presents good
linearities (0.9996, 0.9999 and 0.9998) and recoveries (97%, 96% and 9
6%) with high correlations (0.9158, 0.9715 and 0.9445) for the CGA, tr
igonelline and caffeine, respectively when compared to reverse phase H
PLC techniques. The proposed method appears to be an adequate method f
or quality control in the coffee industry.
