Study on Antioxidant Activities of Pinus armandi franch Seed Oil

Pinus armandi franch is a unique specialty plant in China and its seed oil contains high levels of essential fatty acids (EFA), particularly linoleic acid (LA), which has several pharmaceutical properties. Pinus armandi franch seed oil is a nice resource of linoleic acid With a content of 63% of the total fatty acids. Linoleic acid is an essential fatty acid, whose absence in a normal diet is responsible for the development of various abnormal disorders. This work reported purified LA from Pinus armandi franch seed oil could lower MDA content of lipid peroxidation on rats with hyperlipidemia significantly. TAC activity of liver, heart and serum was enhanced significantly, as well as SOD activity was increased. It demonstrated purified LA from Pinus armandi franch seed oil could improve antioxidant levels of hyperlipidemia rats effectively, enhance the activity of antioxidant enzyme and reduce the content of lipid peroxide, thereby improving lipid metabolism.
