| Research Abstract |
In the study of suppressive effect to stress by intake of sour citrus juice, the characteristic of functional compounds in sour citrus fruits, indigenous products, was examined basally. Ferulic acid derivative, a new antioxidant, was isolated from nihime (indigenous product at Kumano in Mie prefecture). 4-Hydroxy cinnamic acid derivative, a new antioxidant, was identified from meyer lemon. Eureka lemon, sudachi, and niihime exhibited high antioxidative activity of sour citrus fruits. It was suggested that the intake of the lemon fruit water, prepared by the addition of eureka lemon fruit powder to water, during exercise using an exercise bike has a tendency to increase the parasympathetic nerve activity after exercise rest and has suppressive effect of stress. Flavonoids and aroma constituents in lemon fruit were suggested to influence to the effect.
