<p><em>Pumpking seed oil (Cucurbita pepo L.) popular as healthy oil and became natural antioxidant as consist of various unsaturated fatty acid, carotenoid, flavonoid and polyphenolic. The purpose of this research is to study the compounds on pumpkin seed oil that has antioxidant activity by determining fatty acids composition of the oil using gas chromatography-mass spectrometry (GC-MS) and antioxidant activity by inhibiting free-radical DPPH and determination of total polypheolic content as gallic acid using UV-Vis spectrophotometry. Pumpkin seed oil was produced by solvent extraction with Soxhlet apparatus used as sample. Oil samples was reacted to form fatty acid methyl ester for component analysis by GC-MS determination. Antifree-redical activity was determined using UV-Vis spectrophotometry to count the IC<sub>50</sub> value of concentration series of mixed samples and free-radical DPPH compared to vitamin C as standard antioxidant. Total poliphenolic content as gallic acid was determined using UV-Vis Spectrophotometry by reacting samples with Folin-Ciocalteau reagent. Pumpkin seed oil content at least 10 moderate chain fatty acid, saturated and unsaturated, volatile oil and carotenoid. Antixidant activity of pumpkin seed oil with IC<sub>50</sub> value of </em><em>16,90(±0,28)mg/L</em><em> in inhibiting free-radical DPPH and has total polyphenolic content as gallic acid of 0,212%.</em><em></em></p><p><strong><em>Keywords:</em></strong><strong><em> </em></strong><em>pumpkin seed oil, antioxydant, DPPH free radical, polyphenolic, UV sepctrophotometry, GC-MS</em><em>.</em></p>

The Mathematical Model

This paper deals with the supercritical carbon dioxide extraction of pumpkin seed oil (Cucurbita pepo L). Supercritical fluid extraction (SFE) has been used to obtain total lipid extracts from other oilseeds, and it has also proved successful in the isolation and enrichment of sterols from oilseeds. The SFE of pumpkin seed oil on a laboratory scale was investigated in thus paper, with special interest in the influence of the extraction pressure on the overall yield of pumpkin seed oil. Extractions were carried out at the pressures of 15, 25 and 30 MPa and at 313 K, and at a pressure of 30 MPa and the temperatures 313, 323, and 333 K. The yield of the extractions conducted at 15 MPa was rather low, 0.1814 g oil per 1g of seed feed (18.4%) for an extraction time of 14 h. However, extractions at higher pressures yielded greater quantities of the oil; at 22.5 MPa for 9 h, 36.3% of the oil and at 30 MPa for 6 h, 41.0% of the oil. For comparison, hexane extraction of the seed material yielded less than 40% of the oil. Temperature did not influence the extraction yield. At a pressure of 30 MPa, the color of the fractions yielded during successive extraction time intervals varied greatly, from pail yellow (the first 2 h), through orange-yellow (from 2-4 h) to red (after 4 h). The experimental results of the oil yields were compared with the data obtained by the mathematical model of Hong et al., presented in the literature.

Pumpkin Seed Oil

Fatty acid and phytosterol vegetable oils were extracted from seeds of Cucurbita pepo (or pumpkin) into (v/v) hexane. The extract obtained was characterized by the contents of sterols, unsaturated and saturated fatty acids. The content of the bioactive compounds was determined by gas-chromatography FID method. Pumpkin seed oil extracts showed higher content of poly-unsaturated fatty acids (49.10%) than that from saturated fatty acids (28%). Sterols exhibited different molecules dominated by β-sistostérol (47%), Stigmastérol (23.6%) and campesterol (21.5%). Several peaks were present on the FID GC chromatogram of two extracts (fatty acids and sterols respectively). GC spectra confirmed the presence of the predominant bioactive compounds (PUFA, β-sistostérol , Stigmastérol and campesterol). The composition of pumpkin seed oil extract was characterized by FID-GC spectra with maximum at 280 nm.
