PROBLEM TO BE SOLVED: To provide an anti-aging agent.SOLUTION: According to the present invention, an anti-aging agent comprising D-pinitol represented by the general formula (1) as an active ingredient.EFFECT: D-pinitol acts on skin cells to promote IL-1RA synthesis, elastin synthesis, and collagen synthesis to improve the elasticity and flexibility of the skin and promote the synthesis of glycosylated protein-bound receptor 1 involved in the degradation and elimination of aging proteins. Thus, senescent protein does not accumulate in the cells, and the excretion thereof is promoted. As a result, the progression of cell aging is suppressed, and anti-aging effect is therefore exhibited.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2017,JPO&INPIT【課題】抗老化剤の提供。【解決手段】一般式(1)で表されるD-ピニトールを有効成分とする抗老化剤。【効果】D-ピニトールは、皮膚細胞に作用しIL-1RA合成、エラスチン合成、コラーゲン合成を促進し、皮膚の弾力性や柔軟性を改善し、また老化タンパク質の分解や排出に関わる糖化タンパク質結合レセプター1の合成を促進するため、老化タンパク質が細胞内に蓄積されずに排出が促進され、その結果細胞の老化の進行を抑制するため、抗老化作用を示す。【選択図】図5
