From the aerial parts of Phlomis spinidens, two new flavonol bisglycosides, phlomisflavosides A (1) and B (2), were isolated together with the known compounds, astragalin, isoquercitrin, lamiridoside, phlomoside A, shanzhiside methyl ester, 8-O-acetylshanzhiside methyl ester, phlorigidoside C, rodioloside (=salidroside), forsythoside B, citroside A and lariciresinol-4'-O-β-D-glucoside. The structures of the new compounds were elucidated based on spectral and chemical evidence.
从Phlomis spinidens的地上部分,分离出两种新的黄酮醇双糖苷,Phlomisflavosides A (1)和B (2),以及已知化合物黄芪甲苷、异槲皮甙、lamiridoside、Phlomoside A、山栀苷甲酯、8-O-乙酰山栀苷甲酯、根茎苷 C、红景天苷 (=红景天苷)、连翘苷 B、柠檬苷 A 和落叶松树脂醇-4'-O-β-D-葡萄糖苷。根据光谱和化学证据阐明了新化合物的结构。
