The mashua (Tropaeolum tuberosum) is a plant native to the central Andes whose cultivation is concentrated in Colombia, Bolivia, Ecuador and Peru between 3500 and 4100 meters of altitude, this tuber is rich in nutrients due to its bioactive properties, generally in Ecuador it is cultivated in association with the oca, and the melloco. Therefore, the purpose of this work was to characterize by chromatography two varieties of white and yellow Mashua. Therefore, the supercritical fluid extraction method (FSC) was applied in the two varieties, the volatile compounds of the obtained extracts were characterized by Gas Chromatography coupled to a Mass Spectrometer (GC-MS). After characterization, in general, 16 and 11 major volatile compounds considered to belong to the families or functional groups of ketones, fatty acids, furans, furfurals, alcohols, phyto esters, alkaloids and sterols were identified, some of these compounds considered useful for the prevention of diseases such as cancer, they also have antioxidant properties, hypoglycein agent and in the inhibition of the thyroid gland.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
