Polyphenols have been extensively profiled and quantified in commercially grown berries, but similar information is sparsely available for wild berries. Because polyphenolic contents are inherently associated with berries health benefits, determining phenolic profiles is an important step for strategizing potential uses by the industry and for health and nutrition outcomes. Here, we profiled phenolic compounds in wild berries commonly encountered and harvested in the Pacific Northwest region of North America. Huckleberries () of varying phenotypes were found to be comparable to related blueberries in terms of general phenolic classes composition. However, all huckleberries exhibited markedly high levels of cyanidins, and delphinidins or peonidins were also higher in specific phenotypes. Wild black elderberries ( spp. ) were found to have remarkably high phenolic, especially anthocyanins, in line with reports from cultivated elderberries. Saskatoon serviceberries () were found to exhibit high polyphenol content, but with a less diverse profile dominated by quercetin. The most intriguing berry may be the Oregon grape () being the only one exhibiting more than one g of polyphenols per 100 g; as well as a remarkably even distribution of the different anthocyanin classes. All colored wild berries were found to have at minimum comparable total phenolic contents when compared to cultivated and other wild berries, suggesting they should exhibit comparable human health benefits such as antioxidant and metabolic syndrome preventative potential described for these other berries. Overall, our data represents a valuable resource to explore the potential to valorize wild berry species for their specific phenolic profiles and predicted nutritional and health properties. With repeated phenolic profiling to better understand the impact of the environment, the wild berries described here hold promises both as food ingredient applications as well as valuable complement for healthy dietary patterns.
多酚类物质已在商业种植的浆果中得到广泛分析和定量，但关于野生浆果的类似信息却很少。由于多酚含量与浆果的健康益处有着内在联系，确定酚类物质概况是行业制定潜在用途策略以及实现健康和营养目标的重要一步。在此，我们分析了在北美太平洋西北地区常见且可收获的野生浆果中的酚类化合物。结果发现，不同表型的越橘在一般酚类类别组成方面与相关蓝莓相当。然而，所有越橘的矢车菊素含量都显著较高，并且在特定表型中，飞燕草素或芍药色素的含量也较高。野生黑接骨木莓（接骨木属物种）被发现含有非常高的酚类物质，尤其是花青素，这与栽培接骨木莓的报道一致。萨斯卡通花楸莓（花楸属）被发现具有较高的多酚含量，但成分多样性较低，以槲皮素为主。最引人注目的浆果可能是俄勒冈葡萄（十大功劳属），它是每100克中多酚含量超过1克的唯一一种浆果；并且不同花青素类别的分布也非常均匀。与栽培浆果和其他野生浆果相比，所有有色野生浆果的总酚含量至少相当，这表明它们应具有类似的对人类健康的益处，如这些其他浆果所具有的抗氧化和预防代谢综合征的潜力。总体而言，我们的数据是探索野生浆果物种因其特定酚类概况以及预测的营养和健康特性而实现增值潜力的宝贵资源。通过反复进行酚类物质分析以更好地了解环境的影响，这里描述的野生浆果有望作为食品成分应用，以及健康饮食模式的有价值补充。
