The Effect of Extract Preparation on Proportion of Arsenic Species in Beetroot Samples

Original language description

In our experiments, the influence of the extractants for releasing the arsenic compounds from beetroot (Beta vulgaris, L.) growing in arsenic contaminated soil was investigated. Arsenic portions extractable by water and phosphate buffer did not show significant differences between the extraction agents but the extractability was affected by the arsenic concentration in beetroot. Arsenic was almost quantitatively extractable from the samples with the lowest total arsenic concentration, whereas in the samples with the highest total arsenic concentration less than 25% were extractable. Arsenate was the dominant arsenic compound in the extracts. Different pattern was observed in the case of fresh beetroot juice where arsenate varied between 80 ? 100 % regardless of arsenic level. However, loss of arsenic was observed due to filtration of the juice before determination of arsenic compounds. Both effects suggested possible complexes of arsenic with various pigments. The role of plant pigment
