CHUQUIMIA, Felipe et al. DETERMINACIÓN DE LA CAPACIDAD ANTIOXIDANTE Y LA CUANTIFICACIÓN DE COMPUESTOS FENÓLICOS Y FLAVONÓIDICOS DE CUATRO ESPECIES VEGETALES DE LA REGIÓN ANDINA DE BOLIVIA. Rev. Bol. Quim [online]. 2008, vol.25, n.1, pp.76-84. ISSN 0250-5460.

In the present work the 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 of revaluing 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 of famine. 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 (Hipochoeris meyeniana var. brachylepis) and Amañoke (Ombrophytum subterraneum Asplund), a parasite eatable plant that grows on roots of Lepidophillum quadrangulare. The Total Antioxidant Capacity TAC was determined 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 and the Total Flavonoids were determined as catechin equivalents. The higher values of antioxidant activity were observed in amañoke.
