## Abstract Each of the inositol diastereomers have been subjected to low resolution gas chromatographyโmass spectrometry as their hexaโOโtrimethylsilyl (TMSi) ethers and as their hexaacetyl esters. The TMSi ethers of the inositols each possess a unique spectrum consisting of the same ions occurrin
