Since sunflower, flaxseed and olive oils are among the oils commonly used in nutrition in Egypt, the study was conducted to compare the components of these oils and their nutritional value to evaluate them. The fatty acid components of these oils were estimated, and the sterols present in each oil were estimated using the Gas Chromatograph (GC). The physical and chemical properties of each oil were also estimated (specific gravity, refractive index, color, oxidative stability index, saponification value, iodine value, acid value, ester value, peroxide value and % unsaponifiable matter). Linoleic acid was the largest component in sunflower oil (53.33%); oleic acid was the largest one in olive oil (66.65%), while alpha-linolenic acid was the largest component in flaxseed oil (55.34%). For sterols, β-sitosterol (44.86%), stigmasterol (20.33%), campesterol (11.68%), isofucosterol (9.54%) components were the largest in sunflower oil. Squalene (64.14%) and β-sitosterol (16.78%) were the largest sterols in olive oil. While β-sitosterol (28.24%), campesterol (16.37%) and cycloartenyl acetate (12.42%) were the largest sterols in flaxseed oil. The results clearly show a high content of sunflower oil of omega-6 fatty acids, while flaxseed oil was distinguished by its high content of omega-3 fatty acids, and olive oil was the highest in its content of omega-9 fatty acids. Therefore, these oils are well suited for use in nutrition, and more studies are needed to reach the best ratios of the mixture of these oils in biological experiments.","PeriodicalId":280782,"journal":{"name":"Menoufia Journal of Agricultural Biotechnology","volume":"27 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140521238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to evaluate the antioxidant effect of essential oils of basil, thyme and lemongrass by two different methods (FRAP and DPPH) as well as to identify the active ingredients of each oil by GCMS. The results of the fractionation on the GCMS showed that the main components of the essential oils were as follows: basil (L-linalool 59.02% and 1,8-cineole 9.52%), thyme (Thymol 48.06%and p-cymene 38.57%), and lemongrass (Geranial 47.59% and neral 36.27%). In the FRAP method, essential oil of basil was the strongest as an antioxidant (2.35± 0.61 mMol Fe +2 /g), followed by essential oil of thyme (1.96± 0.42 mMol Fe +2 /g), followed by essential oil of lemongrass by a large margin (0.93± 0.21 mMol Fe +2 /g). Whereas, when studying the antioxidant activity by the DPPH method, the results showed through comparison with IC 50 values that, basil essential oil was the strongest antioxidant (IC 50 =144.78 ± 7.19 μg/ml), followed by lemongrass essential oil (IC 50 =170.05 ± 6.97 μg/ml) and finally thyme essential oil (IC 50 =183.45 ± 7.19 μg/ml), w ith a slight difference. The results clearly indicated that the essential oil of basil was the best as an antioxidant compared to the essential oils of lemongrass and thyme in both methods used for the determination of antioxidant activity in vitro (FRAP and DPPH); this makes it a promising source of natural antioxidants that can be used in diets.","PeriodicalId":280782,"journal":{"name":"Menoufia Journal of Agricultural Biotechnology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126126518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
