AB  - Pomegranate seeds are an excellent source of compounds with biological activity. In the present study, the pomegranate seed oil (PSO) was tested for antioxidant and cytotoxic potential. PSO was extracted by super-critical fluid extraction with previous treatment of seeds by microwaves and analysed for its fatty acid profile, carotenoid and tocopherol contents. PSO demonstrated to be a good source of polyunsaturated fatty acids (PUFAs) (83.5%), followed by monounsaturated fatty acid (MUFA) and saturated fatty acid (SFA) (9.5% and 7.0%, respectively). Concerning fatty acid profile, punicic (C18:3), oleic (C18:1) and linoleic (C18:2) acids were the predominant ones. Carotenoids and tocopherols were identified and quantified by HPLC. Results showed that the PSO was a good source of gamma-tocopherol as dominant among investigated compounds (128.6 mg/100 g). The extract was screened for its antioxidant activity using alpha-TEAC assay. Cytotoxic effect was determined by MTT test against malignant HeLa, LS174 and A549 cells (IC50 = 49.51-91.54 mu g/mL), and against normal MRC-5 and EA.hy926 cells (IC50  gt  200 mu g/mL). The best effect was exhibited on cervix adenocarcinoma cell line while no cytotoxicity was found for normal cells pointing out PSO safety.

AB  - Microwave radiation was suggested as a pretreatment technique to increase the yield of pomegranate seed oil. Seeds were pretreated at 100, 250 and 600 W during 2 and 6 min and then extracted by supercritical carbon dioxide (scCO(2)) in high pressure unit as well as by n-hexane in Soxhlet apparatus. Even at the lowest microwave pretreatment parameters applied (100 W for 2 min) increased the yield of seed oil obtained by both extraction techniques compared with untreated seeds (from 27.7 to 34.0% and from 21.6 to 25.5% for Soxhlet and scCO(2) extractions, respectively). Maximal oil yield in Soxhlet extraction (36.3%) was obtained with microwave radiation of 600 W for 6 min while for scCO(2) extraction maximal oil yield (27.2%) was with 250 W for 6 min microwave radiation pretreatment. The qualitative and quantitative composition of fatty acids of the obtained oils was determined by gas chromatography/flame ionization detection and gas chromatography/mass spectrometry. Punicic acid was the most abundant fatty acid in pomegranate seed oil ( gt  60%). Microwave pretreatment of seeds showed negligible influence on profile and the amount of fatty acids in obtained extracts, compared with its significant influence on extraction yield. Our results recognize microwave pretreatment as a promising technique for intensification of oil extraction from pomegranate seeds.
