CHUQUIMIA, Felipe et al. CONTENT OF TRACE ELEMENTS IN FOUR ANDEAN VEGETABLE SPECIES OF BOLIVIA. Rev. Bol. Quim [online]. 2008, vol.25, n.1, pp.53-58. ISSN 0250-5460.

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.

Keywords : Neowerdermannia vorwerckii; Hipochoeris meyeniana; brachylepis; Ombrophytum subterraneum Asplund; Lepidophillum quadrangulare; trace elements; Bolivia; food chemistry; andean species.
