Abstract:This study was conceived to analyze the nutritional value and prospect of the Botrychium ternatum （Thunb.）Sw.The nutritional value and edible risk of wild vegetable were evaluated based on the contents of main nutritional components in Botrychium ternatum （Thunb.） Sw.，the contents of heavy metal elements，and the contents of nitrate and nitrite was calculated， and its comparison with other 4 species of wild vegetables and Chinese herbal medicines was also conducted. The result showed that 1）the contents of crude protein， crude fat， total sugar， cellulose， and ash content of Botrychium ternatum（Thunb.）Sw. were 3.70 % and 3.17 %，8.15 % and 5.40 %，8.50 % and 1.40 %，8.43 % and 1.48 %，7.0 % and 3.80 % respectively and were higher than 4 dai－ ly eating vegetables， and the difference was significant .In addition， the stem leaf and root of Botrychium terna－ tum （Thunb.） Sw.were also rich in VB1 and VB2、VB6 and mineral elements K， Na， Ca， Mg， Fe， Mn，Zn； 2）the content of Hg was zero，but the contents of Cd and Pb were lower vegetables limited standard and Chinese herbal medicines limited standard. Moreover， the stem leaf and root of Botrychium ternatum （Thunb.） Sw. were con－ taining nitrite and nitrate， but the content was very low.
