Buffaloberry fruit a new source of lycopenes.

Buffaloberry (Shepherdia argentea (Pursh) Nutt.) has historically been an important food source used by the North American indigenous peoples. It is widely gathered from the wilds, but its commercial production has been limited. The fruits are rich in carotenoids and phenolics, which potentially have health benefits in the human diet.  We examined the fruit of seven buffaloberry selections from North and South Dakota.  The primary carotenoids, determined by liquid chromatography-mass spectral analysis (LCMS-MS) and nuclear magnetic resonance (NMR), were lycopene (0.27±0.02 g/kg FW) and methyl apo-6’-lycopenoate (0.32±0.03/kg FW).  Methyl apo-6’-lycopenoate (MA6L) comprised the greatest proportion (55%) of the carotenoids.  The fruit also contained high total phenolics (TP) concentrations (9.06±0.71 g gallic acid equivalents/Kg FW). Hydrophilic antioxidant capacity among the seven selections averaged 49.0±6.6 mmol trolox equivalents/kg FW, respectively as measured by Ferric Reducing Ability of Plasma (FRAP) assay.  The soluble solids (SS) and titratable acids (TA) concentrations were 21%, and 2.2%, respectively.  This species is adapted to poor soils, can tolerate drier climates and flourishes on the American Indian Tribal Reservations in the Dakotas. Its nutritional value and the interest by the region’s nascent wine industry provide potential for its establishment as a valuable new crop for marginal lands.
