Antioxidative properties of Jaffa sweeties and grapefruit and their influence on lipid metabolism and plasma antioxidative potential in rats.
Biosci Biotechnol Biochem 2003; 67(4):907-10BB

Abstract

The effective substances (polyphenols, phenolic and ascorbic acids, flavonoids and dietary fibers) and antioxidative activities, using different radical-scavenging tests, were determined for Jaffa sweeties and grapefruit. The antioxidative activities comprised the contributions from polyphenols, phenolic acids, flavonoids and ascorbate components, and were well-correlated with polyphenols and flavonoids. The correlation coefficient between the polyphenols and antioxidative activity varied from 0.73 to 0.99. All applied methods showed that sweeties had higher antioxidative activity than grapefruit. Experiments on laboratory animals show that diets supplemented with sweeties, and to a lesser extent with grapefruit, increased the plasma antioxidative potential and improved the lipid metabolism, especially in the rats fed with added cholesterol. These findings provide additional characterization of the nutritional value of citrus fruits and their influence on the lipid metabolism in rats.
