Abstract Isolation of compounds from the root of Rhodiola sachalinensis RRS yielded tyrosol 1, salidroside 2, multiflorin B 3, kaempferol-3,4′-di-O-β-D-glucopyranoside 4, afzelin 5, kaempferol 6, rhodionin 7, and rhodiosin 8. Quantification of these compounds was performed by high-performance liquid chromatography HPLC. To investigate the antioxidant and anti-inflammatory effects of the compounds, DPPH radical scavenging, NBT superoxide scavenging and nitric oxide production inhibitory activities were examined in LPS-stimulated Raw 264.7 cells. We suggest that the major active components of RRS are herbacetin glycosides, exhibiting antioxidant activity, and kaempferol, exhibiting anti-inflammatory activity.
