Three new steroids named as shuilongguine I ( 1 ), shuilongguine II ( 2 ) and shuilongguine III ( 3 ), together with eleven known compounds were isolated from Polypodium niponicum (Chinese name “Shuilonggu”, Berberidaceae). Their structures were deduced by spectroscopic methods and 2D NMR experiments.
