Resumen
Se implementaron metodologías de análisis por electroforesis capilar (CE) y cromatografía líquida de alta eficiencia (HPLC) para la separación y cuantificación de (±)-catequina, (-)-epicatequina, (-)-epigalocatequina, galato de (-)-epicatequina y galato de (-)-epigalocatequina, en 5 muestras de 3 variedades de cacao cultivadas en Colombia. La técnica de HPLC fue más reproducible que la CE, que, sin embargo, resultó ser más rápida, económica y menos contaminante. Se cuantificaron, por HPLC y CE (estándar externo), (±)-catequina (0,07-0,79 mg/g de cacao) y (-)-epicatequina (1,99-9,66 mg/g de cacao) en los extractos acuosos de las tres variedades de cacao.
