abstract={A rapid high-performance liquid chromatographic method for the determination of organic acids in <i>Brassica rapa</i> L. leaves is reported. Under optimum conditions the detection limits were between 0.26 to 8.00 ¦Ìg/mL and quantification limits were between 0.28 to 12.50 ¦Ìg/mL. The precision results showed that the relative standard deviations of repeatability and reproducibility were ¡Ü 0.84% and ¡Ü 1.49%, respectively. The recovery of the organic acids varied from 97.21 to 99.57%. Organic acids were determined in 44 samples of <i>Brassica rapa</i> var. <i>rapa</i> L.<b> </b>protected under the PGI ¡°Grelos de Galicia¡± in the two plant status (turnip greens and turnip tops). The results showed that all of the samples presented a profile composed of at least four organic acids: citric, malic, oxalic, and ascorbic acids. However, these organic acids were present in different concentrations in turnip greens and turnip tops.},
