Hepatoprotective triterpenoids and lignans from the stems of Schisandra pubescens

One new triterpenoid (1) and 13 known compounds (2-14) were isolated from Schisandra pubescens stems. The structure of the new compound was established on the basis of 1D/2D NMR and HRESIMS spectroscopic analyses. The isolated compounds were evaluated for their hepatoprotective activities against D-GalN-induced cell injury in QSG7701 cells. Compounds 1, 13 and 14 at 10 μM showed hepatoprotective activities, with survival rates of 60.5, 50.4 and...
