In vitro and in vivo antioxidant properties of chlorogenic acid and caffeic acid.

Dietary polyphenols are thought to be beneficial for human health as antioxidants. Coffee beans contain a common polyphenol, chlorogenic acid. Chlorogenic acid is the ester of caffeic acid and quinic acid.

Improvement in intestinal coenzyme q10 absorption by food intake.

Coenzyme Q10 (CoQ10) is widely consumed as a food supplement because of its recognition as an important nutrient in supporting human health. Absorption of compounds from the gastrointestinal tract is one of the important determinants of oral bioavailability. However, the absorption of dietary CoQ10 is slow and limited due to its hydrophobicity and large molecular weight.

Antioxidant activity of a novel extract from bamboo grass (AHSS) against ischemia-reperfusion injury in rat small intestine.

Production of free radical species in cells and body tissues is known to cause many pathological disorders. Therefore, free radical scavengers play an important role in the prevention of various human diseases. Bamboo grass, Sasa senanensis, is a native Japanese plant.

Protective effect of lutein on ischemia-reperfusion injury in rat small intestine.

Lutein is a carotenoid and it has antioxidant effects. Lutein may have a protective effect on ischemia reperfusion (I/R) injury induced by free radical species. However, little is known about the protective effect of lutein on I/R injury in vivo.
