Two species of native wild blueberries from the tropical regions of Central America and South America contain two to four times more antioxidants than those sold in U.S. markets. The discovery is the result of an analysis of the compounds contained in neotropical blueberries grown in The New York Botanical Garden.

The study was conducted by Professor Edward Kennelly, a biologist at Lehman College in the Bronx, an expert on medicinal plants and Paola Pedraza, Botany of The New York Botanical Garden, whose specialties include blueberry South America

"No one had turned to it, but the results are very promising," said Pedraza. In the study, published in the Agricultural and Food Chemistry, researchers examined five species of neotropical blueberries. The two species showing the greatest amount of antioxidants were the Cavendish and Anthopterus Wardii grandifolia.

Antioxidants found in fruits and vegetables have been associated with the decrease of some chronic diseases and may even protect against cardiovascular disease, inflammation and even cancer. Of the five species of neotropical blueberries used in the study, four came from the Nolen Greenhouses at the New York Botanical Garden and the Atlanta Botanical Garden.

This wild species are not commercially available, for now. Scientists believe that the fruit has potential to become a popular food item or a nutritional supplement to its high content of antioxidants become known.

"I think it's just a matter of time before starting to make them more accessible," says Pedraza. More than 600 variations neotropical are related to the species of the fruit called "highbush blueberry, very common in American markets. Several of them, including the two species in question are native to high-elevation forests of the Andes, one of the most threatened ecosystems in the world.
