Oligosaccharide and glucose esters from the roots of Polygala arillata

Abstract

The root of plant Polygala arillata has been used in the Oriental medicine as a tonic and for the treatment of certain diseases. Our current research on phytochemical profile of the roots of P. arillata led to the isolation of a new oligosaccharide ester (1, polygaloside), a new glucose ester (7, arillatoside), along with five known sucrose esters (2–6). Their structures were elucidated on the basis of extensive chemical and spectroscopic methods as well as comparison with those reported in the literature. The occurence of various oligosaccharide esters in P. arillata including unique compounds plays taxonomical impact and suggests potential in medicinal uses of the title plant.
