Chlorogenic Acids as a Potential Criterion in Coffee Genotype Selections

A systematic study by HPLC was conducted to determine the content of chlorogenic acids in green coffee beans of the Variedad Colombia (Coffea arabica Caturra var. x Hibrido de Timor)and in other genotypes of interest of C. arabica, Coffea canephora, Hibrido de Timor, and the F1 offspring derived from the crossing Caturra x Hibrido de Timor. Comparisons were made of the total content of these acids, their quantitative differences, and the presence or absence of some of them, using parametric statistical techniques and multivariate analysis. Total content differences were found between C. canephora accessions, between Tipica and Caturra varieties of C. arabica, and between Hibrido de Timor accessions. The chromatographic profile comparisons with principal component analysis separated in the first component C. canephora accessions from the rest of the genotypes, whereas the second component separated C. canephora accessions.
