Chenopodium quinoa Willd. is an ancient food crop that has provided nutrition to Andean populations for thousands of years. BRS Piabiru is a quinoa genotype developed and adapted to tropical climate by the Brazilian Agricultural Research Corporation. In this work, BRS Piabiru quinoa was evaluated concerning its nutritional, physicochemical and phenolic composition and also its bioactive properties. This variety showed high carbohydrate and protein contents and a low-fat level, composed of 86% of unsaturated fatty acids, 60% of which are polyunsaturated fatty acids. Four organic acids were detected, with quinic acid as the most abundant, while α- and γ-tocopherols were the vitamin E isoforms found. Quercetin and kaempferol glycosides were the main phenolic compounds in the quinoa extract, which also revealed relevant antioxidant and antimicrobial activities, with no toxic effect. These results support the potential of BRS Piabiru quinoa as a nutritious food crop and a source of bioactive compounds.
藜麦是一种古老的粮食作物，几千年来一直为安第斯地区的人们提供营养。BRS Piabiru 是巴西农业研究公司开发和适应热带气候的藜麦基因型。在这项工作中，评估了 BRS Piabiru 藜麦的营养、物理化学和酚类成分以及生物活性特性。该品种碳水化合物和蛋白质含量高，脂肪含量低，其中 86%为不饱和脂肪酸，60%为多不饱和脂肪酸。检测到四种有机酸，其中以奎宁酸含量最高，而 α-和 γ-生育酚则是发现的维生素 E 异构体。藜麦提取物中的主要酚类化合物为槲皮素和山奈酚糖苷，其还具有相关的抗氧化和抗菌活性，无毒性作用。这些结果支持 BRS Piabiru 藜麦作为一种有营养的粮食作物和生物活性化合物的来源的潜力。
