AB  - The objective of this study was to investigate the nutritional value of seven samples of cold pressed pumpkin oil of different origins and influence of seed origin on the content of the most important bioactive components. Four samples of a pumpkin oil is obtained by cold pressing of the seeds of domestic and Austrian varieties, and three samples of cold pressed oils were obtained from the seeds of unknown origin, taken by free choice in the market. As indicators of the nutritional values are determined by the composition and content of fatty acids, tocopherols and sterols. In the composition of the fatty acid were oleic dominant (34.2 +/- 0.09-43.9 +/- 0.04%) and linolenic fatty acid (30.8 +/- 0.09-46.9 +/- 0.015%). This study confirmed that the oil pumpkin dominant beta+gamma-tocopherol, whose contents ranged from 34.65 +/- 0.03 to 44.59 +/- 0.69 mg/100 g. We determine the composition and content of Delta(7)-phytosterols, especially for specific oil pumpkins. It was detected five Delta(7)-sterols: spinasterol, Delta(7,22,25)-stigmastatrienol, Delta(7,25)-stigmastadienol, Delta(7)-stigmasterol and Delta(7)-avenasterol. Dominant content was Delta(7,22)-stigmastadienol or spinasterol with 39.98 to 50.31% of the total content of sterols.

AB  - The composition and content of certain bioactive components of the cold pressed oil obtained from six samples of pumpkin seeds (Cucurbita pepo L.) cultivated in Serbia were analyzed by GC and GC/MS. The composition and content of fatty acids, tocopherols and phytosterols, and the total content of squalene were determined. The results indicate oil's excellent quality, with high contents of monounsaturated fatty acids (37.1 +/- 0.70-43.6 +/- 0.69 g/100 g of total fatty acids), total tocopherols (38.03 +/- 0.25-64.11 +/- 0.07 mg/100 g of oil), sterols (718.1 +/- 6.1-897.8 +/- 6.8 mg/100 g of oil) and especially squalene (583.2 +/- 23.6-747 +/- 16 mg/100 g of oil). High content of squalene, phytosterols and monounsaturated fatty acids recommend the use of this type of the oil in the nutritional and medical purposes.

AB  - Antioxidant (AO) activity of cold pressed pumpkin (Cucurbita pepo L.) seed oil, produced from three naked and one hulled variety, was assessed using a DC polarographic assay based on a hydrogen peroxide scavenge (HPS). Results are expressed as the decrease of the anodic oxidation current of hydrogen peroxide obtained upon addition of methanolic extract of the investigated oils. Strict correlations of HPS and (1) radical scavenging capacity against the stable free radical 1,1-diphenyl-2-picrylhydrazyl (DPPH) (0.99), (2) the induction period estimated by a Rancimat test (0.99) and (3) total phenolic content estimated by Folin-Ciocalteu (FC) assay (0.99) were obtained. In addition, a significant correlation of HPS and the content of delta-tocopherol (0.87), squalene (0.67) and color CIE a* (-0.89) was found. Based on the results reported, the polarographic assay was found to be suitable for determination of AO activity as an indicator of the quality and oxidative stability of oil.
