摘要：

Phytochemical studies on Skimmia wallichii resulted in the isolation of skimmiwallichin, skimmiwallin and a new cycloartanol type compound skimmiwallinin. The structure of skimmiwallinin is elucidated as 3 beta-methoxy-24-methyl-24-ethyl-9,19-cyclolanost-25(26)-ene on the basis of spectral studies. The structures of skimmiwallichin and another tetracyclic triterpene, now named skimmiwallin, were revised and established to be 3 beta-methoxy-24,24-diethyl-9,19-cyclolanost-25(26)-ene and 3 beta-methoxy-25-ethyl-9,19-cyclolanost-24(24')-ene, respectively.
