Plant-based pigments are widely present in nature, they are classified depending on their chemical structure as tetrapyrroles, carotenoids, polyphenolic compounds, and alkaloids and are extensively used in medicine, food industry, clothes, and others. Recently they have been investigated due to their role in the areas of food processing, food safety and quality, packaging, and nutrition. Many studies indicate a relationship between bioactive pigments and Non-Communicable Diseases derived from oxidative stress. Their biological applications can help in preventing oxidative injuries in the cell caused by oxygen and nitrogen reactive species. Those pigments are easily degraded by light, oxygen, temperature, pH conditions, among others. Nanotechnology offers the possibility to protect bioactive ingredients and increase its bioavailability after oral administration. Safety to humans (mainly evaluated from toxicity data) is the first concern for these products. In the present work, we present a comprehensive outlook of the most important plant-based pigments used as food colorants, the principal nanotechnology systems prepared with them, and the relationship of these compounds with the oxidative stress and related Non-Communicable Disease.

植物性颜料广泛存在于自然界中，根据其化学结构可分为四吡咯，类胡萝卜素，多酚化合物和生物碱，广泛用于医药，食品工业，服装等。最近，由于它们在食品加工，食品安全和质量，包装和营养领域中的作用而受到研究。许多研究表明，生物活性色素与氧化应激引起的非传染性疾病之间存在关联。它们的生物学应用可以帮助防止由氧和氮反应性物质引起的细胞氧化损伤。这些颜料容易在光，氧气，温度，pH条件等条件下降解。纳米技术提供了在口服后保护生物活性成分并提高其生物利用度的可能性。这些产品首先要考虑对人体的安全性（主要从毒性数据进行评估）。在当前的工作中，我们对用作食品着色剂的最重要的植物基颜料，使用它们制备的主要纳米技术系统以及这些化合物与氧化应激和相关的非传染性疾病之间的关系进行了全面展望。
