Comparison of mild extraction procedures for determination of arsenic compounds in different parts of pepper plants (Capsicum annum, L.)

Original language description

In the present work eight extraction agents (water, methanol/water mixtures in various ratios, methanol, a 20 mM ammonium phosphate buffer, and a methanol/phosphate buffer) were tested for the extraction of arsenic compounds from fruits, stems+leaves, and roots of pepper plants grown on soil containing 17.2 mg kg-1 of total arsenic. The arsenic compounds in the extracts were determined with HPLC-HG-ICPMS. While for fruits (87%&#61617; 3.3% extraction yield) and roots (96% &#61617; 0.6% extraction yield)pure water was the most effective extraction agent, the 20 mM ammonium phosphate buffer at pH=6 extracted about 50% of the arsenic from stems+leaves. Decreasing extractability of the arsenic compounds was observed with increasing methanol concentrationsfor all parts of the pepper plant. In pepper fruits, As(III), As(V), and DMA were present (25, 37, and 39% of the extractable arsenic). In stems+leaves and roots As(V) was the major compound (63 and 53%) followed by As(III) representing
