Antioxidant capacity and secondary metabolites in four species of Andean tuber crops: native potato (Solanum sp.), mashua (Tropaeolum tuberosum Ruiz & Pavo´ n), Oca (Oxalis tuberosa Molina) and ulluco (Ullucus tuberosus Caldas)
Four species of edible tubers endemic to and domesticated in the Andes, native potato (Solanum sp.), mashua (Tropaeolum tuberosum Ruiz & Pavón), oca (Oxalis tuberosa Molina) and ulluco (Ullucus tuberosus Caldas), were studied for their antioxidant capacity and associated secondary metabolites. The antioxidant capacity was measured using ABTS− radicals and total phenolics, carotenoids, anthocyanin, betaxanthin and betacyanin content were also characterized.
