Abstract
Ecuador has among its foods a number of potatoes and tubers that are not only nutritious, but are also attributed properties as coadjutant in the treatment of different illnesses. The objective of this study was to conduct a comparative study of the mashua tuber (Tropaeolum tuberosum spp tuberosum Ruiz & Pavon, Kuntze), in its three pink, yellow and black varieties, by comparing the physicochemical characteristics and antioxidant activity. The comparative study was carried out on tubers obtained in the province of Pichincha, Quito-Ecuador. The physicochemical parameters were determined by the identification of the secondary metabolites present in the hydroalcoholic extracts, the quantification of phenols and flavonoids, and the characterization of the extracts by gas chromatography coupled to mass spectrometry and the antioxidant activity by three test methods. As a result, significant differences were found between the three varieties studied.

The objective of this study was to conduct a comparative study of the mashua tuber (Tropaeolum tuberosum spp tuberosum Ruíz & Pavón, Kuntze), in its three pink, yellow and black varieties, by comparing the physicochemical characteristics and antioxidant activity
The physicochemical parameters were determined by the identification of the secondary metabolites present in the hydroalcoholic extracts, the quantification of phenols and flavonoids, and the characterization of the extracts by gas chromatography coupled to mass spectrometry and the antioxidant activity by three test methods
With the purpose of determining the quality of the extracts, we did a physical chemical parameter analysis, considering the organoleptic properties, pH, total solids, refraction index and relative density; in Table 3 we present the results of the study
Summary
Food and health at a global level are a growing concern between different gov-. This has led to a search into traditional, natural resources, which may have not been properly distributed, being ignored among Ecuadorian populations [1]. Looking back at these traditional products, they noticed an Andean tuber and investigated its nutritional and pharmacological qualities of ancestral use [2]
