Elevation of Serum Carotenoids after Continual Ingestion of Tomato Juice.

Determination of carotenoids in tomato juice by liquid chromatography.

A high-performance liquid chromatography method was developed to determine the various carotenoids in tomato juice. A C30 column and a mobile phase of acetonitrile-1-butanol (7:3, v/v) (A) and methylene chloride (B) with the following gradient elution were used: 99% A and 1% B intitally, increased to 4% B in 20 min, 10% B in 50 min and returned to 1% B in 55 min. Sixteen carotenoids, including ...

Tomato juice intake suppressed serum concentration of 8-oxodG after extensive physical activity

BACKGROUND DNA is constantly exposed to reactive oxygen species (ROS), spontaneously arising during the normal oxygen metabolism. ROS may result in temporary as well as permanent modifications in various cellular components such as lipids, proteins and DNA, which may have deleterious consequences. Demonstrating that a dietary supplementation of antioxidants can reduce oxidative DNA damage may p...

Carotenoids in human buccal mucosa cells after 4 wk of supplementation with tomato juice or lycopene supplements.

BACKGROUND Lycopene has been identified as a phytochemical with potentially protective health benefits. OBJECTIVE Our objective was to monitor lycopene changes in buccal mucosa cells (BMCs) in response to 3 vehicles for oral delivery of lycopene. DESIGN Fifteen healthy subjects ingested lycopene-rich tomato juice, tomato oleoresin, lycopene beadlets (each containing 70-75 mg lycopene) and a...

Urinary excretion of anthocyanins in humans after cranberry juice ingestion.

Cranberry, which is rich in polyphenols, including anthocyanins and proanthocyanidins, has been found to have various effects beneficial to human health, including prevention of urinary tract infections. These effects have been associated with polyphenols in the fruit. We investigated the excretion of anthocyanins in human urine after ingestion of cranberry juice. Eleven healthy volunteers cons...
