| The nannyberry plant (Viburnum lentago) is native to the eastern part of North America. The objective of this research is to measure the antioxidant activity, quantities of compounds responsible for this activity and quantities of nutrients in nannyberries. High levels of antioxidant activity (>9mg quercetin equivalents/g dry weight) were found in all five samples. Their antioxidant activity levels were close to that of blueberries (10.3 mg quercetin equivalents/g dry weight), which were used for comparison. The quantities of soluble phenolics and total polyphenols were determined by a colorimetric method using the Folin-Ciocalteu's phenol reagent. Nannyberries had moderate quantities of soluble phenolics (>40 umol of catechin equivalents/g dry weight) and high quantities of total polyphenols (>140 umol catechin equivalents/g dry weight).
