 note = {We investigated the forms of silicon in soluble pectin substances (SPS) extracted by hot water from the cell wall of the roots of rice (Oryza sativa L.), wheat (Triticum aestivum L.), maize (Zea mays L.), soybean (Glycine max L.), eggplant (Solanum melongena L.), sunflower (Helianthus annuum L.), tomato (Solanum lycopersicum L.) and cucumber (Cucumis sativus L.) plants. The silicon content of SPS was not related to the amount of SPS extracted. However, the silicon content of SPS increased with increasing sugar content, except in soybean. When rice and eggplant SPSs were loaded onto Sephadex G-50, most silicon was co-eluted with sugar and uronic acid in the void volume (V_0). Digestion with pectinase remained most silicon with the sugar and uronic acid in the V_0, but part of the silicon was found in the lower molecular weight area with uronic acid. When loading onto the same column after hydrolyzing
the eggplant SPS with hydrochloric acid, most silicon and sugar was eluted near the V_t, but the fraction numbers of both peaks were different, and a larger peak of silicon and a small peak of sugar remained in the V_0. Sugars in the SPS were mostly arabinose, galactose and glucose, but the silicon content of the SPS from some plants decreased with the lower glucose with cis-hydroxyl group in the 2, 4, 5-position. These results suggest that a part of the silicon in the SPS might form complexes with cis-hydroxyl groups in the glucose, and that if silicon content is high, as in rice, the remaining silicon might polymerize to glucose-silicon complexes.},
