(ST. LOUIS): Researchers at the Missouri Botanical Garden’s William L. Brown Center have discovered extraordinarily high levels of omega fatty acids in a species which they encountered in Northern Peru. Omega fatty acids are essential for human health and must be obtained through food sources. Omega-3 fatty acids are also widely used in cosmetics.

Rainer Bussmann and Ashley Glenn along with Peruvian colleague Caroline Tellez first described Plukenetia huayllabambana in 2009 after collecting it in the Mendoza forest region of the Peruvian Amazon. However, the high levels of omega fatty acids were only discovered in recent weeks.

Plukentia species are known as “Sacha Inchi” or forest peanuts and the seeds of the Plukenetia huayllabambana contain omega-3, omega-6 and omega-9 fatty acids in large quantities. Plukenetia huayllabambana is also rich in proteins and vitamin E and the seeds have a 96 percent digestibility factor. The plant has high potential as a food source, not only for the local population, but also on a global scale if sustainable harvest methods can be developed. Given the potential for both consumption and cosmetic uses, it also provides economic potential for the area and is an alternative to illegal crops.

“This species illustrates the importance of taxonomy,” said Bussmann. “Science takes time and previously unknown species often have great potential once they are fully studied.”

The William L. Brown Center of the Missouri Botanical Garden is dedicated to the study of useful plants and the relationships between humans, plants and the environment. Scientists strive to conserve plant species for the benefit of future generations. WLBC scientists work in 12 countries across four continents.

The Missouri Botanical Garden is one of the three largest plant science programs in the world.

The Missouri Botanical Garden focuses its work on areas that are rich in biodiversity yet threatened by habitat destruction, and operates the world’s most active research and training programs in tropical botany. Garden scientists collaborate with local institutions, schools and indigenous peoples to understand plants, create awareness, offer alternatives and craft conservation strategies. The Missouri Botanical Garden is striving for a world that can sustain us without sacrificing prosperity for future generations, a world where people share a commitment to managing biological diversity for the common benefit.
