         4 . The heat shock protein expression-inducing agent according to  claim 1 , which is in the form of a pharmaceutical composition, quasi-drug composition or food and beverage composition. 
     
     
         5 . A sleep improving agent comprising a compound represented by formula (I): 
       
         
           
           
               
               
           
         
         wherein R is a lower alkyl, phenyl, or hydroxyphenyl, 
         or a salt thereof. 
       
     
     
         6 . The sleep improving agent according to  claim 5 , wherein R is isopropyl, phenyl, or hydroxyphenyl. 
     
     
         7 . The sleep improving agent according to  claim 5 , wherein R is isopropyl. 
     
     
         8 . The sleep improving agent according to  claim 5 , which is in the form of a pharmaceutical composition, quasi-drug composition or food and beverage composition. 
     
     
         9 . An autonomic nerve-adjusting agent comprising a compound represented by formula (I): 
       
         
           
           
               
               
           
         
         wherein R is a lower alkyl, phenyl, or hydroxyphenyl, 
         or a salt thereof. 
       
     
     
         10 . The autonomic nerve-adjusting agent according to  claim 9 , wherein R is isopropyl, phenyl, or hydroxyphenyl. 
     
     
         11 . The autonomic nerve-adjusting agent according to  claim 9 , wherein R is isopropyl. 
     
     
         12 . The autonomic nerve-adjusting agent according to  claim 9 , which is in the form of a pharmaceutical composition, quasi-drug composition or food and beverage composition. 
     
     
         13 . An anti-stress agent comprising a compound represented by formula (I): 
       
         
           
           
               
               
           
         
         wherein R is a lower alkyl, phenyl, or hydroxyphenyl, 
         or a salt thereof. 
       
     
     
         14 . The anti-stress agent according to  claim 13 , wherein R is isopropyl, phenyl, or hydroxyphenyl. 
     
     
         15 . The anti-stress agent according to  claim 13 , wherein R is isopropyl. 
     
     
         16 . The anti-stress agent according to  claim 13 , which is in the form of a pharmaceutical composition, quasi-drug composition or food and beverage composition.
