The blueberry, a deciduous shrub in the Ericaceae family, is celebrated for its delightful flavor, sweetness, and abundance of anthocyanins and antioxidants, qualities that have garnered significant attention for their potential health benefits. Blueberries grown in diverse environments and exhibit varied anthocyanin profiles, often influenced by factors such as altitude and climate. Varietal groups worldwide have been bred and categorized based on their growth habits and specific cold requirements, particularly with southern highbush cultivars thriving in temperate climates, demonstrating tolerance to higher altitudes or cooler climates-a result of hybridizations involving various species. In the Colombian Andes, southern highbush blueberries thrive in unique high-altitude conditions, leading to exceptional quality due to the region's cool climate and specific soil characteristics. In this context, this study aimed to chemically characterize and differentiate three southern highbush blueberry cultivars (i.e., 'Biloxi,' 'Legacy' and 'Sharpblue') cultivated in a Colombian Andean plateau and compare them to three commercially available highbush blueberries. This comprehensive evaluation involved examining total phenols, flavonoids, anthocyanin content, and DPPH· free-radical scavenging capacity, as well as conducting anthocyanin-targeted profiling via HPLC-DAD-HRMS. Through supervised multivariate analyses such as sPLS-DA, this study delved into the pattern recognition of those anthocyanins that could potentially serve as markers for quality and cultivar-related chemical trait determination. These findings locate blueberry-derived anthocyanins in a metabolic context and afford some insights into southern highbush blueberry cultivar differentiation to be used for further purposes.
蓝莓是杜鹃花科的落叶灌木，以其美味、甜味和丰富的花青素和抗氧化剂而闻名，这些特性因其潜在的健康益处而引起了广泛关注。在不同环境中种植的蓝莓表现出不同的花青素特征，通常受海拔和气候等因素的影响。世界各地的品种组根据其生长习性和特定的冷需求进行了培育和分类，特别是南方高丛品种在温带气候中茁壮成长，表现出对高海拔或凉爽气候的耐受性——这是各种物种杂交的结果。在哥伦比亚安第斯山脉，南方高丛蓝莓在独特的高海拔条件下茁壮成长，由于该地区凉爽的气候和特定的土壤特征，导致其品质卓越。在这种情况下，本研究旨在对在哥伦比亚安第斯高原种植的三个南方高丛蓝莓品种（即“Biloxi”、“Legacy”和“Sharpblue”）进行化学表征和区分，并将它们与三种市售高丛蓝莓进行比较。这种综合评估包括检查总酚、类黄酮、花青素含量和 DPPH·自由基清除能力，并通过 HPLC-DAD-HRMS 进行花青素靶向分析。通过 sPLS-DA 等有监督的多元分析，本研究深入探讨了那些可能作为质量和品种相关化学特征决定因素的花青素的模式识别。这些发现将蓝莓衍生的花青素置于代谢背景下，并为进一步了解南方高丛蓝莓品种分化提供了一些见解。
