Purification and molecular structure of digalactosyl myo-inositol (DGMI), trigalactosyl myo-inositol (TGMI), and fagopyritol B3 from common buckwheat seeds by NMR

- First NMR-based structural characterization of DGMI, TGMI and fagopyritol B3.
- Structures of all six known fagopyritols are now completed.
- First report of a nicotinic acid glucoside in buckwheat.
- First report of a soluble apiose-containing carbohydrate in buckwheat.
- Simultaneous characterization of multiple compounds by NMR in complex mixtures.
