Abstract
Phytin has been extracted from peas by a method depending upon its insolubility in hot 8% acetic acid. It has been characterized on the paper chromatogram and found to be a pure compound. Micro-analysis of this compound gives a carbon-phosphorus ratio compatible with that of a hexaphosphate. Comparison of pea phytin with commercial and synthetic calcium phytate (prepared by Posternak's method) using paper partition chromatography has shown that commercial phytin is composed of two organic phosphates (in addition to orthophosphate), one of which resembles pea phytin. The various compounds formed in addition to phytic acid in Posternak's synthesis have been examined and some have been tentatively identified.
