| The fatty acid compositions, polyphenol contents and antioxidant properties of eight kinds of vegetable oils, including perilla oil, sesame oil, flaxseed oil, broccoli oil, soybean oil, peanut oil, maize oil, and sunflower seed oil, were compared and discussed. The results indicated that the eight vegetable oils had different fatty acid composition ratios. Among them, peanut oil had the highest oleic acid content of 4398%, sunflower seed oil had the highest linoleic acid content of 65.00%, and perilla oil had the highest linolenic acid content of 63.89%.The DPPH free radical scavenging ability of eight vegetable oils decreased in the following order: sesame oil>soybean oil>maize oil>broccoli oil>flaxseed oil>peanut oil>perilla oil>sunflower seed oil, which was consistent with the polyphenol contents. While the Fe3+ reducing ability decreased in the following order: sesame oil>soybean oil>broccoli oil>peanut oil>flaxseed oil>maize oil>perilla oil>sunflower seed oil. |
