Research Abstract	In the present study, comprehensive analysis system was used to identify improvement effects in mental functions by dietary constituents. As a result, depression and anxiety were more declined in certain peptide-fed mice than in protain-fed mice. Then, brain weight was more increased and neurogenesis was more prompted in the former. In addition, certain peptide added to culture medium of PC12 cells induced neurite elongation. Furthermore, H. herinaceum intake has the possibility to reduce depression and anxiety. These results suggest that comprehensive analysis system is useful to evaluate the improvement effect of dietary constituents in mental functions.
