The acetone extract of the roots of Rhodiola sachalinensis has furnished six phenolic compounds which exhibited significant scavenging effects against DPPH free radical. The structures of these compounds were identified and determined as gallic acid (1), (-)-epigallocatechin 3-O-gallate (2), kaempferol (3), kaempferol 7-O-$\alpha$ -L-rham nopyranoside (4), herbacetin 7-O-$\alpha$ -L-rhamnopyranoside, (5) and rhodiolinin (6) by physico-chemical and spectral evidences.
