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.

巴西藜麦BRS Piabiru的营养价值，理化特性和生物活性。
藜藜藜。是一种古老的粮食作物，数千年来一直为安第斯人口提供营养。BRS Piabiru是巴西农业研究公司开发并适应热带气候的藜麦基因型。在这项工作中，对BRS Piabiru quinoa的营养，理化和酚类成分以及其生物活性进行了评估。该品种显示出较高的碳水化合物和蛋白质含量，并且脂肪含量低，由86％的不饱和脂肪酸组成，其中60％是多不饱和脂肪酸。检测到四种有机酸，其中奎尼酸含量最高，而α-和γ-生育酚是发现的维生素E亚型。藜芦提取物中主要的酚类化合物是槲皮素和山emp酚糖苷，还显示了相关的抗氧化剂和抗菌活性，没有毒性作用。这些结果支持了BRS Piabiru quinoa作为营养食品和生物活性化合物来源的潜力。
