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 simultaneously with mono- and disaccharides.
