COMPARACIÓN DE DOS MÉTODOS DE EXTRACCIÓN Y DETECCIÓN CROMATOGRÁFICA DE ÁCIDO TENUAZÓNICO A PARTIR DE MUESTRAS DE TOMATE COMPARISON OF TWO METHODS FOR THE EXTRACTION AND CHROMATOGRAPHIC DETECTION OF TENUAZONIC ACID FROM TOMATO SAMPLES

This paper evaluates two methods of chromatographic detection and two methods of tenuazonic acid (TA) extraction from tomato paste. Chromatographic detection using a binary mobile phase consisting of acetonitrile and phosphate buffer, at pH 3, was compared to a
