From the 70% ethanol extract of the stems of Rhodiola bupleuroldes, five compounds were isolated by repeated silica gel column chromatography. Their structures were determined by spectroscopic (UV, IR, ESI-MS, 1H NMR, 13C NMR and 2D NMR) and chemical methods as rhobupcyanoside A (1), p-coumaric acid (2), 4, 5-dihydroxy-3-methoxybenzoic acid (3), schizandriside (4) and kaempferol (5). Among them, 1 was a new compound, and 2-5 were isolated from R. bupleuroldes for the first time.
