The objective of this study was to characterize the nutritional compounds of interest present in vegetables known as non-conventional, in Brazil. The following evaluations were carried out: antioxidant activity, phenolic compounds, vitamin C, calories, carbohydrates, humidity, lipids, proteins, fiber, acidity and quantification of minerals (P, K, Ca, Mg, S, Cu, Fe, Mn, Zn and B). The species studied were Amaranthus hybridus L., Amaranthus viridis L., Basella alba L., Eryngium campestre L., Hibiscus sabdariffa L., Lactuca canadensis L., Rumex acetosa L., Stachys byzantina K. Koch, Tropaeolum majus L. and Xanthosoma sagittifolium L. Representative samples of plant structures of interest were harvested from each species suitable for human consumption such as leaves, flowers and flower buds. The results were submitted to multivariate analysis - principal components analysis (PCA). All the species present nutritional compounds of interest in different levels among the evaluated structures.
本研究的目的是对巴西被称为非常规蔬菜中的营养成分进行表征。进行了以下评估：抗氧化活性、酚类化合物、维生素C、卡路里、碳水化合物、湿度、脂质、蛋白质、纤维、酸度以及矿物质（磷、钾、钙、镁、硫、铜、铁、锰、锌和硼）的定量分析。所研究的物种有杂交苋、绿穗苋、落葵、田野刺芹、玫瑰茄、加拿大莴苣、酸模、绵毛水苏、旱金莲和箭叶黄体芋。从每个物种适合人类食用的植物结构（如叶子、花朵和花蕾）中采集了具有代表性的样本。将结果进行多变量分析——主成分分析（PCA）。在所有评估的结构中，所有物种均含有不同水平的目标营养成分。
