Article abstract of DOI:10.1016/S0031-9422(00)83821-2

A new flavanol glycoside, symplocoside, was isolated from the MeOH extract of the stem bark of Symplocos uniflora and its constitution and conformation were elucidated by means of MS, ¹H and ¹³C NMR spectroscopy as (2R:3R)-7-O-β-D-glucopyranosyl-3′-O-methyl-(-)-epicatechin.
