  Triglyceride accumulation inhibitory effects of phenylpropanoid glycosides from Boschniakia rossica Fedtsch et Flerov

  摘要：

  Bioassay-guided fractionation led to isolation of five new phenylpropanol glycosides, rossicasides G (1), H (2), I (3), J (4), and K (5), together with seven known compounds (6-12) from Boschniakia rossica. Their structures were elucidated by chemical and spectroscopic methods (UV, IR, HRESI-TOF-MS, 1D and 2D NMR). Activity screening results showed that some isolates had TG accumulation inhibitory effects in HepG2 cells. Furthermore, the structure-activity relationship was partly clarified.
