Abstract
The main objective of this study was to determine total oil, total phenol, antioxidant activity and mineral contents of hull-less pumpkin seeds and also fatty acid composition of seed oils. The results indicated that total oil, total phenol content and antioxidant activity values were found between 33.04 and 46.97 %, 56.94 and 87.15 mg GAE/100 g and 0.19 and 11.75 %, respectively (p < 0.05). Linoleic, oleic, palmitic and stearic acids were the most prominent fatty acids in all genotypes. The most abundant mineral in the studied seeds, which belong to different genotypes, was potassium (2704.75-1033.63 ppm) followed by phosphorus (3569.690-9108.835 ppm) and magnesium (1275.15-3938.16 ppm) (p < 0.05). Particularly genotype-1 was the richest seed in essential fatty acids and minerals.
