Abstract
En el trabajo presente se llevó a cabo la cuantificación de hierro, cinc y cobre de cuatro especies de la verdura de la región andina de Bolivia. Las plantas estudiadas fueron: los rizomas de chijura (Stangea rhizantha); las raíces del cactus achacana (Neowerdermannia vorwerckii), el blanco de las hojas basales en forma de rosa de la planta de siki (Hipochoeris meyeniana var.brachylepis) y el tallo de la flor de amañoke (Ombrophytum subterraneum Asplund), la parte comestible de una balanoforacea que parásita las raíces de thola (Lepidophillum quadrangulare) y que también se usa como medicina. Las plantas seleccionadas se usan como comestibles, en particular en tiempos de hambre. La cuantificación por AAS se llevó a cabo por triplicado. Varios resultados interesantes con respecto al contenido de elementos traza de las especies estudiadas se obtuvieron. Todas las especies presentaron valores altos de Fe, y los valores más altos se obtuvieron para la chijura (10.9 mg/100 g). Con respecto a Zn, la achacana (2.6 mg/100 g) presentó el valores más alto, el amañoke dio (1.5 mg/100 g) y la chijura dio (1.8 mg/100 g). Con respecto al contenido de Cu, el amañoke destaca con 0.46 mg/100g.
In the present work the determination of iron, zinc and copper of four vegetable species of the Andean region of Bolivia was carried out. The plants are: the rhizomes of chijura (Stangea rhizantha); the roots of the cactus achacana (Neowerdermannia vorwerckii), the white basal leaves in form of rose of siki (Hipochoeris meyeniana var.brachylepis) and the shaft of the flower of amañoke (Ombrophytum subterraneum Asplund), the eatable part of a Balanophoraceae that parasites on the roots of thola (Lepidophillum quadrangulare) and it is also used as a medicine. The selected plants are used as foodstuffs, in particular in times of famine. The quantification by AAS was carried out in triplicate. Several interesting results regarding the trace element content of the studied species were obtained. All the species presented high Fe values, and the highest values were obtained for chijura (10.9 mg/100 g). Regarding Zn, achacana presented the higher value (2.6 mg/100 g), amañoke gave (1.5 mg/100 g) and chijura gave (1.8 mg/100 g). Regarding the content of Cu, amañoke stands out with 0.46 mg/100 g.
