The invention provides novel compounds with a chemical structure similar to that of gingerol useful as a component for foods, pharmaceutical products, cosmetics and the like. After intensive investigations, the inventors found the gingerol analogues represented by the following general formulae (1) and (2). Additionally, the inventors found that these compounds had excellent properties as an inhibitor of tyrosinase activity and an antioxidant. By using the following compounds of the invention as a component for cosmetics, for example, cosmetics suppressing the generation of speckles and spots can be produced. By using the compounds as a component for foods, quality deterioration due to the oxidation of foods can be prevented. Gingerol analogues represented by the following general formula (1). (In the formula (1), R1 represents an alkyl group with one to 18 carbon atoms; R2 is hydrogen atom or methyl group; R3 is methyl group or ethyl group; and A represents an alkylene group with one to 4 carbon atoms.) Gingerol analogues represented by the following general formula (2). (In the formula (2), R1 represents an alkyl group with one to 18 carbon atoms; R2 is hydrogen atom or methyl group; R3 is methyl group or ethyl group; and A represents an alkylene group with one to 4 carbon atoms.)
