Oleanane-type triterpenoid saponins from Silene armeria

Twelve triterpenoid saponins, including seven compounds (i.e., armerosides A–G) hitherto unknown, were isolated from whole plants of Silene armeria. Their structures were established based on extensive spectroscopic analyses and chemical methods. From a biosynthetic perspective, C-23 oxidation of the sapogenin appears to be a key factor in the glycosylation pathway.

Phenolic glycosides from Kaempferia parviflora

Three phenolic glycosides were isolated together with two known flavonol glycosides from the H2O-soluble fraction of rhizomes of Kaempferia parviflora. Their structures were determined to be rel-(5aS,10bS)-5a,10b-dihydro-1,3,5a,9-tetrahydroxy-8

DETERMINATION OF CONFIGURATION OF MONOSACCHARIDES BY HPLC ON DIASTEREOISOMERIC 1-DEOXY-1-(N-ACETYL-α-METHYLBENZYLAMINO)ALDITOL ACETATES

Acyclic diastereoisomers, 1-deoxy-1-(N-acetyl-α-methylbenzyl-amino)alditol acetates, are readily obtained by reductive amination of sugars with chiral α-methylbenzylamine in the presence of sodium cyanoborohydride.Ten pairs of enantiomers of common monosaccharides are resolved by an adsorption HPLC on the diastereoisomers.
