Established procedures for the fractionation of calcium in plant tissue have been investigated. Because of the varying solubilities and the imprecise nature of many forms of calcium, such as pectate and phytate, most fractions resulting from successive solvent extraction have little meaning. A modified procedure involving extraction in acetic acid and HCI is shown to give a good measure of that calcium associated with oxalate.
