Senegoses A--E, oligosaccharide multi-esters from Polygala senega var. latifolia Torr. et Gray

From the roots of Polygala senega var. latifolia Torr. et Gray five new oligosaccharides, called senegoses A--E, were isolated and their structures were elucidated by spectroscopic and chemical means. These oligosaccharides were esterified with acetic, benzoic, trans-ferulic and cis-ferulic acids.
