Xanthine oxidase inhibitors from Vietnamese Blumea balsamifera L.


From the MeOH extract of the aerial part of Blumea balsamifera L., a new dihydroflavonol, (2R,3S)-(-)-4'-O-methyldihydroquercetin (1), together with seven known compounds has been isolated. Their structures were elucidated on the basis of spectroscopic data. Compounds 1-4 and 6-8 displayed significant xanthine oxidase inhibitory activity in a concentration… (More)
