Abstract

ABSTRACT. Pumpkins are increasingly regarded as functional foods since they contain valuable nutrients and bioactive substances that have positive health effects. The number of bioactive components depends on the origins and parts of the pumpkin, which define its antioxidant capacity. This study evaluated the total phenolic, total flavonoid, and ascorbic acid content and antioxidant activities of three parts of pumpkin from four different sample origins and investigated the correlation between them. The content of bioactive components in pumpkin from Dukem, Ethiopia, was highest in the flesh, peel, and seeds compared to the other sample areas. The Pearson correlation result indicated a strong relationship between the total phenolic, flavonoid, and ascorbic acid contents of pumpkin and their respective antioxidant activities. This study found that the total phenolic, total flavonoid, and ascorbic acid contents and antioxidant activity varied across the pumpkin sample sources and pumpkin parts.

南瓜果肉、果皮和种子中总酚、总黄酮、抗坏血酸含量及抗氧化活性的测定

摘要。南瓜越来越被视为功能性食品，因为它们含有宝贵的营养素和生物活性物质，对健康有积极影响。生物活性成分的数量取决于南瓜的来源和部位，这决定了南瓜的抗氧化能力。本研究评估了四种不同产地南瓜三个部分的总酚、总黄酮、抗坏血酸含量和抗氧化活性，并探讨了它们之间的相关性。与其他样品区相比，埃塞俄比亚杜克姆南瓜的果肉、果皮和种子中的生物活性成分含量最高。Pearson相关结果表明，南瓜的总酚、黄酮和抗坏血酸含量与其各自的抗氧化活性之间存在很强的关系。本研究发现，南瓜样品来源和南瓜部位的总酚、总黄酮、抗坏血酸含量和抗氧化活性各不相同。关键词：南瓜，类黄酮，酚，抗坏血酸，抗氧化活性，埃塞俄比亚牛。化学。Soc.Ethiop。2023,37（5），1093-1108.DOI:https://dx.doi.org/10.4314/bcse.v37i5.3
