Triterpene glycosides of ladyginia bucharica III. Structure of ladyginoside C
SummaryThe structure of ladyginoside C — a trioside of oleanolic acid — has been established. The carbohydrate chain is attached to the hydroxyl at C3 of the aglycone and consists of β-D-glucopyranosyl-(1→4)-α-L-arabopyranosyl-(1→4)-β-D-glucopyranuronic acid.
Thin-layer chromatography of carbohydrates.
The separation of carbohydrates on thin layers of silica gel is due first of all to the type and quantity of impregnating salt. 
 
The results of chromatography of carbohydrates on thin layers of silica gel in the presence of sodium mono- and dihydrogen phosphate are often better than those of paper chromatography (e.g. a good separation of complex mixtures, less sensitivity to inorganic impurities, and faster separation). 
 
The present method can be recommended for the study of the monosaccharide composition of oligo- and polysaccharides.
