Betalains are a group of plant originated pigments with chemopreventive potential. The aim of this study was to relate the composition of betalains and chosen biological activities (antioxidant, cytotoxic, anti-genotoxic and influence on enzymatic activities) for extracts from differently pigmented varieties of prickly pear (yellow, orange and red) and beetroot (white and red). The assumption was that phytocomplexes of tested varieties of the same plant species would exhibit generally similar chemical composition differing mostly in betalain content, which will be reflected by their biological activity. Betalain composition analysis and antioxidant profiles confirmed that the content and composition of these pigments is strongly correlated with the antioxidant activity of tested plant extracts measured by spectrophotometric methods and CAA test. However, the results of determinations of other biological activities showed that in the case of actual plant foods, there was no simple relationship between betalain content or composition and chemopreventive potential.
甜菜红素是一类具有化学预防潜力的植物源性色素。本研究的目的是将甜菜红素的组成与所选的生物活性（抗氧化、细胞毒性、抗遗传毒性以及对酶活性的影响）相关联，这些生物活性来自不同色素含量的仙人掌（黄色、橙色和红色）和甜菜根（白色和红色）提取物。我们的假设是，同一植物物种的不同品种的植物复合体会表现出一般相似的化学成分，主要区别在于甜菜红素的含量，这将反映在它们的生物活性上。甜菜红素组成分析和抗氧化特性证实，这些色素的含量和组成与通过分光光度法和 CAA 测试测量的测试植物提取物的抗氧化活性密切相关。然而，其他生物活性测定的结果表明，在实际植物性食物的情况下，甜菜红素含量或组成与化学预防潜力之间没有简单的关系。
