Isolation of Inositol Hexakisphosphate from Soils by Alkaline Extraction and Hypobromite Oxidation

Inositol hexakisphosphates are extracted from soil in strong alkali and isolated from other organic phosphates by hypobromite oxidation. The procedure yields the four stereoisomeric forms of inositol hexakisphosphate in a form suitable for spectroscopic or chromatographic identification.
