ABSTRACT

Pumpkin is a genus of plants belonging to the Cucurbitaceae family comprising several species, the most common of which are Cucurbita maxima, Cucurbita pepo, Cucurbita moschata. Pumpkins are characterized by a high content of carotenoids, polyphenolic compounds, mineral components, and vitamin C. The level of bioactive compounds is affected by the pumpkin cultivar, which determines its antioxidant properties. In this study, the antioxidant potential of 19 pumpkin cultivars of Cucurbita pepo and Cucurbita moschata species was determined and compared using ABTS, DPPH, FRAP, chelating activity and ORAC assay. Results of the study confirmed the high diversity of pumpkin cultivars in terms of their antioxidant activity. It was also shown that the antioxidant activity is more affected by the type of cultivar than by the pumpkin species. The obtained results indicate that cultivars such as ‘Delicata’, ‘Baby Boo’, ‘Cream of the Crop’ were characterized by particularly high antioxidant activity.

摘要

南瓜是属于葫芦科（Cucurbitaceae）科的植物的属，包括几种物种，其中最常见的是最大南瓜属（Cucurbita maxima），西葫芦（Cucurbita pepo），西葫芦（Cucurbita moschata）。南瓜的特点是类胡萝卜素，多酚化合物，矿物质和维生素C含量高。生物活性化合物的水平受南瓜品种的影响，这决定了南瓜的抗氧化特性。在这项研究中，19个品种南瓜的抗氧化能力西葫芦和南瓜使用ABTS，DPPH，FRAP，螯合活性和ORAC测定来确定和比较这些物种。研究结果证实了南瓜品种在抗氧化活性方面的高度多样性。还表明，抗氧化剂活性受品种类型的影响比受南瓜种类的影响更大。获得的结果表明，诸如“ Delicata”，“ Baby Boo”，“ Cream of the Crop”的栽培种具有特别高的抗氧化活性。
