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

Three galactosyl cyclitols, digalactosyl myo-inositol (assigned the trivial name DGMI), trigalactosyl myo-inositol (assigned the trivial name TGMI), and trigalactosyl d-chiro-inositol (fagopyritol B3), were isolated from common buckwheat (Fagopyrum esculentum Moench) seeds. Structures of the three compounds were determined by 2D NMR spectroscopy. DGMI is α-d-galactopyranosyl-(1→6)-α-d-galactopyranosyl-(1→1)-1l-myo-inositol, TGMI is α-d-galactopyranosyl-(1→6)-α-d-galactopyranosyl-(1→6)-α-d-galactopyranosyl-(1→1)-1l-myo-inositol, and fagopyritol B3 is α-d-galactopyranosyl-(1→6)-α-d-galactopyranosyl-(1→6)-α-d-galactopyranosyl-(1→2)-1d-chiro-inositol.

Phenolics, sugars, antimicrobial and free-radical-scavenging activities of Melicoccus bijugatus Jacq. fruits from the Dominican Republic and Florida.

Edible fruits of the native South American tree Melicoccus bijugatus Jacq. are consumed fresh or in traditional food, drink and medicinal preparations. Some therapeutic effects of these fruits may be due to phenolics and sugars.

Characterization of phenolics by LC-UV/vis, LC-MS/MS and sugars by GC in Melicoccus bijugatus Jacq. 'Montgomery' fruits.

Fruits of the native South American tree Melicoccus bijugatus Jacq. (Sapindaceae) are consumed for both dietary and medicinal purposes, but limited information is available about the phytochemistry and health value of M. bijugatus fruits.

Molecular structure of lathyritol, a galactosylbornesitol from Lathyrus odoratus seeds, by NMR.

The molecular structure of galactosyl-D-(-)-bornesitol, a novel compound isolated from sweet pea seeds, was determined to be alpha-D-galactopyranosyl-(1-->3)-1-O-methyl-1D-myo-inositol by 1D and 2D NMR spectroscopy and is assigned the trivial name lathyritol.
