Analysis of Pinitol (DC-613)

Pinitol, a compound present in pine and legumes, is a methylester of chiro-inositol (an optical isomer of myo-inositol) effective in lowering blood glucose levels. For this reason, it is sold in combination with myo-inositol (a compound known for inhibiting fat storage) as a diet supplement for treating metabolic syndrome. Here, RSpak DC-613 columns for sugar analysis were used here to analyze pinitol and myo-inositol, chiro-inositol simultaneously with mono- and disaccharides.
