Introduction: Aflatoxins (AFs) are fungal secondary metabolites with potent carcinogenic properties´ and pistachios are susceptible oilseeds for AF contamination. Objective: To determine the concentration of the four AFs types (AFB1, AFB2, AFG1 and AFG2) from 48 pistachio samples from Mexico, six from Turkey and 3 from Greece. Methods: The AFs of the 57 analysed samples of pistachio seeds were quantified by liquid chromatography. The calibration curves had R2 values near 1. The LOD values were low and were acceptable to identify and quantify the AFs. The recovery percentages were >80%, which indicated that the extraction method was efficient, and in the selectivity test, no interference between the retention times of the AFs and the pistachio matrix were observed. Results: This study validated an analytical method developed to quantify AFs in.. View More»
