The purpose of this study was to investigate composition and content of phenolic compounds in seeds of common buckwheat (Fagopyrum esculentum Moench) cultivars from Western, Central and Southeastern Europe grown in the Balkan area, and to compare them with cultivars from the Balkan. Mostly detected hydroxycinnamic acids in seeds of the investigated cultivars were caffeic and chlorogenic acid derivatives. More than ten different flavanols were detected in the investigated seeds, based on which all tested buckwheat cultivars were divided into two groups: those with high propelargonidins (epiafzelechin-epicatechin) and those with high procyanidins contents. 'Novosadska' had the highest level of phenolic acids, proanthocyanidins, flavones and most of the flavonols. However, 'Bosna 1' and 'Bosna 2' were highlighted with the greatest rutin content (up to 46 times higher than in other cultivars). All buckwheat cultivars had quite high antioxidant capacity (more than 80% of neutralized radicals), yet, 'Novosadska', 'Godijevo', 'Spacinska 1' and 'Bamby' excelled.
本研究旨在调查生长在巴尔干地区的来自西欧、中欧和东南欧的普通荞麦（Fagopyrum esculentum Moench）品种种子中酚类化合物的组成和含量，并将其与来自巴尔干地区的品种进行比较。在研究的品种种子中主要检测到的羟基肉桂酸衍生物是咖啡酸和绿原酸。在所研究的种子中检测到了十多种不同的黄烷醇，根据这些黄烷醇，所有测试的荞麦品种被分为两组：具有高原儿茶素（表儿茶素-表没食子儿茶素）和高原花青素含量的组。“诺瓦萨德卡”（Novosadska）具有最高水平的酚酸、原花青素、黄酮类化合物和大多数类黄酮。然而，“波斯尼亚 1 号”（Bosna 1）和“波斯尼亚 2 号”（Bosna 2）以最高的芦丁含量（比其他品种高 46 倍）而突出。所有荞麦品种都具有相当高的抗氧化能力（超过 80%的自由基被中和），然而，“诺瓦萨德卡”（Novosadska）、“戈迪耶沃”（Godijevo）、“斯帕钦斯卡 1 号”（Spacinska 1）和“班比”（Bamby）表现出色。
