Study of suppressive effect to stress of sour citrus juice

在研究酸柑橘汁对应激的抑制作用时，对土特产酸柑橘果实中功能性成分的特性进行了初步研究。 从三重县熊野土特产nihime中分离得到一种新的抗氧化剂阿魏酸衍生物。 4-从meyer lemon中鉴定出一种新的抗氧化剂羟基肉桂酸衍生物。 尤里卡柠檬、甜橙和新姬表现出较高的抗氧化活性。 有人建议，在使用健身自行车进行运动期间，通过将尤里卡柠檬果粉添加到水中而制备的柠檬果水的摄入具有增加运动休息后的副交感神经活动的趋势，并且具有抑制应激的效果。 柠檬果实中的风味物质和香气成分对柠檬的保鲜效果有一定的影响。

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.
