Popis: Aiming to achieve a precise method with easy application, this study presents the development and validation of a fast method for quantification of vitamin DL-α-tocopherol in quinoa seeds. The methodology was based on an extraction procedure using ultrasonic bath and determination by normal-phase HPLC with UV-VIS detector. Validation parameters showed adequate linearity, relative standard deviations between 0.5 and 0.8% (n=10), limits of detection and quantification were 3.0 ng/mL and 11.0 ng/mL, respectively. Moreover, testing the robustness of the method suggested that it was not changeable with time or condition. The results showed that this method is accurate and simple and thus applicable in laboratories for determination of DL-α-tocopherol in quinoa seeds.
