Senegoses J-O, oligosaccharide multi-esters from the roots of Polygala senega L

From the roots of Polygala senega L. six new oligosaccharides, called senegoses J-O, were isolated and their structures were elucidated by spectroscopic and chemical means. These oligosaccharides were esterified with acetic, benzoic, p-coumaric and ferulic acids.
