Chlorogenic acids as a potential criterion in coffee genotype selections

A systematic study by HPLC was conducted to determine the content of chloro genic acids in green coffee beans of the Variedad Colombia (Coffea arabica Caturra var, x Hibrido de Timer) and in other genotypes of interest of C. a rabica, Coffea canephora, Hibrido de Timer, and the F1 offspring derived fr om the crossing Caturra x Hibrido de Timer. Comparisons were made of the to tal content of these acids, their quantitative differences, and the presenc e or absence of some of them, using parametric statistical techniques and m ultivariate analysis. Total content differences were found between C. canep hora accessions, between Tipica and Caturra varieties of C, arabica, and be tween Hibrido de Timer accessions. The chromatographic profile comparisons with principal component analysis separated in the first component C, canep hora accessions from the rest of the genotypes, whereas the second componen t separated C. canephora accessions.
