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.
从柴胡红景天茎的70%乙醇提取物中，通过反复硅胶柱色谱法分离得到了5种化合物。通过光谱法（紫外、红外、电喷雾质谱、核磁共振氢谱、核磁共振碳谱和二维核磁共振）和化学方法确定它们的结构分别为柴胡红景天氰苷A（1）、对香豆酸（2）、4,5-二羟基-3-甲氧基苯甲酸（3）、五味子苷（4）和山奈酚（5）。其中，1为新化合物，2-5首次从柴胡红景天中分离得到。
