چکیده
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 moderate inhibitory activities against NO production with IC50 value of 88.2, 42.1 and 74.3 μM, respectively.
