ESTUDIO COMPARATIVO POR ELECTROFORESIS CAPILAR Y CROMATOGRAFíA LíQUIDA DE ALTA EFICIENCIA DE CATEQUINAS EXTRAíDAS DE CINCO VARIEDADES DE CACAO COLOMBIANO

analytical methodologies based on capillary electrophoresis (ce) and high performance liquid chromatography (hplc) were implemented for the separation and quantitation of (±)-catechine, (-)-epicatechine, (-)-epigallocatechine, (-)-epicatechine gallate and (-)-epigallocatechine gallate in 5 samples of 3 cacao varieties grown in colombia. hplc was found to be more reproducible than ce, which turned out to be faster, more economical and less contaminant. (±)-catechine (0,07- 0,79 mg /g cacao) and (-)-epicatechine (1,99-9,66 mg /g cacao) were determined in aqueous extracts of the 3 cacao varieties.
