Fruits of Rhus parviflora were extracted with 80% aqueous methanol (MeOH), and the concentrated extract was partitioned using ethyl acetate (EtOAc), n-butanol (n-BuOH), and $H_2O$, successively. Purification of EtOAc fraction led to isolation of fifteen polyphenols of which structures were identified by spectroscopic methods including 2D-NMR. Most compounds apart from compound 10 inhibited low density lipoproteinoxidation within $IC_{50}$ value of $10{\mu}M$. Among compounds, taxifolin (2), quercetin 3-O-${\alpha}$-L-rhamnopyranoside (13), agathisflavone (5) sulfuretin (4), and aureusidin (3) showed $IC_{50}$ values 0.9, 0.8, 5.8, 2.9, and $2.4{\mu}M$ which were of highly significant in comparison positive control butylated hydroxytoluene with $IC_{50}$ value of $2.1{\mu}M$. The results indicate fruits of R. parviflora as a source of antihypercholesterolemic compounds.
