METHOD OF REGULATING CIRCADIAN RHYTHM, AND METHOD OF PREPARING CIRCADIAN RHYTHM REGULATORY AGENT

摘要

Disclosed are a method of preparation and method of application of a circadian rhythm regulatory agent having as an active ingredient an alkylresorcinol represented by general formula (I) below and a circadian rhythm regulatory agent containing as an active ingredient an alkylresorcinol-containing extract from a cereal or a nut containing an alkylresorcinol of the following general formula (I). In the following general formula (I), R₁ is a saturated or unsaturated alkyl group; and R₂ is hydrogen or methyl. In general formula (I), R₁ is preferably at the para-position with respect to R₂, and R₁ is preferably a saturated or unsaturated alkyl group having 15 to 27 carbon atoms. [Chem. 1];
