The 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), a new glucose ester (7), along with five known sucrose esters (2-6). Their structures were elucidated on the basis of extensive chemical and spectroscopic methods (NMR and MS spectra) as well as comparison with the literature data. To the best of our knowledge, the occurence of various oligosaccharide esters in P. arillata including unique compounds play taxonomical impact and suggest potential in medicinal uses of the title plant.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
