Sesquiterpenoids of Torilis japonica fruit.
From the methanolic extract of Torilis japonica D. C. fruit (Umbelliferae), two eudesmane-type sesquiterpenoids were isolated together with five previously described sesquiterpenoids. From the results of spectral analyses, they were characterized as 4(15)-eudesmene-1beta,5alpha-diol and 4alpha,15-epoxyeudesmane-1beta,6alpha-diol, respectively. The absolute stereostructures of these sesquiterpenoids were elucidated by the modified Mosher's method.
