PROBLEM TO BE SOLVED: To provide a new sirtuin activity promoter targeted at mammals.SOLUTION: A sirtuin activity promoter contains an alkylresorcinol represented by formula (I) and an alkylresorcinol represented by general formula (2). (In the formula (I), R1 represents a C25 saturated or unsaturated alkyl group, and R2 represents a hydrogen atom or methyl group.) (In the formula (II), R3 represents a C15-24 saturated or unsaturated alkyl group, and R4 represents a hydrogen atom or methyl group.)SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】哺乳類を対象とした新たなサーチュイン活性促進剤の提供。【解決手段】式(I)で表されるアルキルレゾルシノールと一般式(2)で表されるアルキルレゾルシノールとを含有する。(式中、R1は炭素原子数25の飽和又は不飽和のアルキル基を示し、R2は水素原子又はメチル基を示す。)(式中、R3は炭素原子数15~24の飽和又は不飽和のアルキル基を示し、R4は水素原子又はメチル基を示す。)【選択図】図1
