SOLUTION: General formula (I) (In the formula, R 1 is an alkyl group or an alkenyl group, and R 2 is a hydrogen atom, an alkyl group, an alkyl group having a hydroxyl group, an alkenyl group, an acyl group, or a glycosyl group.) Or a therapeutic agent for heart disease containing a physiologically acceptable salt thereof as an active ingredient, and a compound of the general formula (II): (However, in the formula, R 1 is an alkyl group having 1 to 10 carbon atoms or an alkenyl group having 2 to 10 carbon atoms, and R 2 is an alkyl group having 2 to 4 carbon atoms and having a hydroxyl group.) A benzopyran derivative or a physiologically acceptable salt thereof. |
