ABSTRACT
In the present workthe measurement of the antioxidant capacity and the quantification of flavonoids and phenolic compounds are carried out in four vegetable species of the Andean region of Bolivia with the purpose ofrevaluing our ancestral foods and in this way, in a future to be able to take advantage of its nutritious and biological properties. The selected plants are used as foodstuf, in particular in times offamine. The selected plants are: the rhizome of Chijura (Stangea rhizantha); the root of the cactus Achacana (Neowerdermannia vorwerckii) and the white basal leaves in form of rose of Siki (Hipochoerismeyeniana var. brachylepis) and Amañoke (Ombrophytum subterraneum Asplund), a parasite eatable plant that grows on roots of Lepidophillum quadrangulare. The Total Antioxidant Capacity TAC wasdetermined by two methods ABTS (2,2' Azinobis-3-etil-benzotiazolin-6-sulfonic acid) and FRAP (Ferric Reduction Ability of Plasma). The Total Poliphenols were determined by the method of Folin-Ciocalteau andthe Total Flavonoids were determined as catechin equivalents. The higher values of antioxidant activity were observed in amañoke./ En el presente trabajo se realizó la determinación de la capacidadantioxidante y la cuantificación de compuestos fenólicos y flavonóidicos de cuatro especies vegetales de la región andina de Bolivia con el fin de revalorizar algunos de nuestros alimentos ancestrales...
