PROBLEM TO BE SOLVED: To provide a method for extracting a silicon from a plant.SOLUTION: The method for extracting a water-soluble organosilicon includes immersing high-temperature steam obtained by heating silicon hydrogen water in a carbonized rice husk layer to filter. The water-soluble organosilicon is generated by mixing the high-temperature steam generated by heating the silicon hydrogen water with a silicon extracted from the carbonized rice husk.【課題】植物からケイ素を抽出する方法を提供する。【解決手段】珪素水素水を加熱した高熱蒸気を、炭化籾殻層に潜らせ、濾過した水溶性有機珪素の抽出方法である。珪素水素水を加熱し生成される高熱蒸気と、炭化籾殻から抽出した珪素とを混合して生成された水溶性有機珪素を得る。【選択図】図１
