Portuguese wild blackberries trump commercial varieties

March 13, 2012  By Marg Land

March 6, 2012 – Wild blackberries native to the Portuguese flora have a stronger neuro-protective effect than commercially available varieties.

This is the major finding of a work conducted by researchers from ITQB’s Disease & Stress Biology Laboratory in collaboration with the Animal Cell Technology Unit, the CEDOC and the James Hutton Institute (Dundee, UK). The work is published in the European Journal of Nutrition.

Researchers tested the effect of digested extracts of two wild species of blackberries (Rubus brigantinus and R. vagabundus) on in vitro cultured neurons. Further molecular analysis revealed that the observed neuro-protective action results from cellular adaptative responses that go beyond simple antioxidant effects. Since tests were carried out with digested extracts within the concentration range found in human plasma in real live conditions, researchers expect these wild fruits to have a potential benefit for age-related neurodegenerative diseases.


According to the researchers, these findings also open a window for the protection of Portuguese blackberries. Moreover, this may trigger the introduction of new “superfruits” or food ingredients, with higher nutritional and health benefits, in the market.
