Abstract: In order to exploit the resource of Osmunda japonica Thunb, the composition of nutrients in wild and cultivated Osmunda japonica Thunb were comparatively analyzed by routine analytical analysis, ICP semi-quantitative analysis and automatic amino acid analyzer. A significant difference in the contents of chlorophyll and polysaccharides between both species was observed (P =0.006 and 0.002, respectively). The content of crude protein had a little difference between both species. In addition, the content of amino acids revealed irregular variations between both species. Moreover, a variety of mineral elements such as Fe, Zn, Mn and Cu in Osmunda japonica Thunb were detected. The contents of K and P elements in wild Osmunda japonica Thunb were higher than those in cultivated species, while the content of S was the opposite.
