    Evaluación de biofactorías vegetales para la producción y extracción de antocianinas a partir de Col Lombarda (Brassica oleracea var. capitata f. rubra)

    In this research, the seed disinfection and germination process was optimized, exposed to different experimental conditions such as: culture media (Murashige and Skoog Complete and without nitrates); growth regulators (Methyl Jasmonate and Salicylic Acid) and genetic transformation (AtMYB12 and GUS) to obtain transformed seedlings and roots. Extracts were obtained to analyze total anthocyanin content and antioxidant and anti-inflammatory capacities. Analyses showed that the use of Gibberellic Acid at 4 degrees improved the germination rate by 83.33 percent. The Murashige and Skoog medium without nitrates favored the accumulation of anthocyanins in the seedlings, reaching a total anthocyanin content of 45.07 mg Cyanidin-3-glucoside per-100 g, with an antioxidant capacity of 65 percent and anti-inflammatory activity of 76.49 percent. In the transformed roots the transcription factor AtMYB12 in Murashige and Skoog complete medium reported better results with a total anthocyanin content of 49.49 mg Cyanidin-3-glucoside per-100 g; antioxidant capacity of 72.10 percent and anti-inflammatory activity of 79.4 percent. Statistical results suggest that the culture medium influences the production of anthocyanins, and the transformed roots in the transcription factor are the most relevant. These results suggest that genetic transformation and the optimization of culture conditions can increase anthocyanin production.
