Phenolics and nutrient profiles of bog bilberry (Vaccinium uliginosum L.) collected from high mountain pastures in northeast Anatolia (Turkey) were examined for the first time in this study. The major soluble sugar identified in the berry was fructose, following by glucose, and the main organic acid identified was citric acid, followed by malic acid. Eleven phenolic acids and 17 anthocyanin 3-glycosides were identified and quantified. Caffeic acid in the free and glycoside forms and syringic acid in the ester form were the major phenolic acids, and the major individual anthocyanin present in the berry was malvidin 3-glucoside (24%). The highest total phenolics and anthocyanin contents were obtained from the anthocyanin fraction in conjunction with the highest antioxidant capacity, followed by the polyphenolic and aqueous fractions, FRAP, ORAC and DPPH, in that order. Our findings can be used to compare bog bilberry with other Vaccinium berries and to help clarify the relative potential health benefits of different berries.
本研究首次对从土耳其安纳托利亚东北部高山牧场采集的笃斯越橘（Vaccinium uliginosum L.）的酚类物质和营养成分进行了检测。浆果中鉴定出的主要可溶性糖是果糖，其次是葡萄糖，鉴定出的主要有机酸是柠檬酸，其次是苹果酸。鉴定并定量了11种酚酸和17种花色苷3-糖苷。游离和糖苷形式的咖啡酸以及酯形式的丁香酸是主要的酚酸，浆果中存在的主要单体花色苷是矢车菊素3-葡萄糖苷（24%）。花色苷组分的总酚和花色苷含量最高，抗氧化能力也最强，其次是多酚组分和水相组分，抗氧化能力依次为铁离子还原抗氧化能力（FRAP）、氧自由基吸收能力（ORAC）和1,1-二苯基-2-三硝基苯肼（DPPH）。我们的研究结果可用于将笃斯越橘与其他越橘属浆果进行比较，并有助于阐明不同浆果相对潜在的健康益处。
