Wrinkle reduction agent, lipolysis accelerator, composition for external use on skin, and food or beverage composition

Abstract

An antiwrinkle agent, lipolysis promoter, external composition for skin, and food and beverage composition having for an active ingredient thereof a compound represented by general formula (1): (wherein R represents a hydrogen atom or an acyl group having 2 to 20 carbon atoms) or an extract obtained from guinea ginger and/or an acylation treatment product of said extract.

1 . A method for alleviating wrinkles occurring in photo-aging on skin, comprising applying to skin a composition comprising an effective amount of an active ingredient chosen from compounds of formula (1): 
     
       
         
         
             
             
         
       
     
     wherein R represents a hydrogen atom or an acyl group having from 2 to 20 carbon atoms. 
   
   
       2 . The method according to  claim 1 , wherein R is a hydrogen atom. 
   
   
       3 . The method according to  claim 1 , wherein the active ingredient is an extract obtained from guinea ginger and/or an acylation treatment product of said extract. 
   
   
       4 . A method for promoting lipolysis, comprising applying to skin a composition comprising an effective amount of an active ingredient chosen from compounds of formula (1): 
     
       
         
         
             
             
         
       
     
     wherein R represents a hydrogen atom or an acyl group having from 2 to 20 carbon atoms. 
   
   
       5 . The method according to  claim 4 , wherein R is a hydrogen atom. 
   
   
       6 . The method according to  claim 4 , wherein the active ingredient is an extract obtained from guinea ginger and/or an acylation treatment product of said extract. 
   
   
       7 . A method for promoting lipolysis, comprising eating or drinking a food or beverage composition comprising an effective amount of an active ingredient chosen from compounds of formula (1): 
     
       
         
         
             
             
         
       
     
     wherein R represents a hydrogen atom or an acyl group having from 2 to 20 carbon atoms. 
   
   
       8 . The method according to  claim 7 , wherein R is a hydrogen atom. 
   
   
       9 . The method according to  claim 7 , wherein the active ingredient is an extract obtained from guinea ginger and/or an acylation treatment products of said extract.
