A novel isoflavone glycoside, peseudobatigenin 7-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
). Their structures were characterized by Q-TOF mass, optical rotation, UV, 1D and 2D-NMR spectroscopic data. Compounds 3
showed moderate inhibitory activities against NO production with IC50
value of 88.2, 42.1 and 74.3 μM, respectively.
