A novel isoflavone glycoside, peseudobatigenin 7-O-[β-d-apiofuranosyl-(1''''→5''')-O-β-d-apiofuranosyl-(1'''→6'')]-β-d-glucopyranoside, namely sympracemoside (1), was isolated from the aerial parts of Symplocos racemosa along with 15 known flavonoids (2-16). Their structures were characterized by Q-TOF mass, optical rotation, UV, 1D and 2D-NMR spectroscopic data. Compounds 3, 9, 16 showed moder...
The light petroleum extract from the roots of Lonchocarpus muehlbergianus Hassl contained nine flavonoids, including six new ones. These are 2,4-cis-2,4,5,8-tetramethoxy-(2'',3'':6,7)-furanoflavan; 2,4-cis-4-hydroxy-2,5,8-trimethoxy-(2'',3'':6,7)-furanoflavan; 2,4-cis-2-prenyloxy-4,5,8-trimethoxy-(2'',3'':6,7)-furanoflavan; 2,4-cis-2-prenyloxy-4-hydroxy-5,8-dimethoxy-(2'',3'':6,7)-furanoflavan;...
dietary flavonoids show beneficial effects in the prevention of chronic diseases. however, flavonoid bioavailability is poor, probably due to their interaction with serum albumins. in the current work, the binding interactions of eight related flavonoids, sharing a similar core structure, with bovine serum albumin (bsa) were investigated by fluorescence spectroscopy. the binding affinities of t...
